INTRODUCTIONINTRODUCTIONNote: If you cant wait to start using Dynomation-5, feel free to jump ahead to INSTAL-LATION on page 16 or program OVERVIEW on page 22, but dont forget to read the rest of this manual when you have time. Also, please complete the Registration Form that appears when you first start your software. It entitles you to receive tech support, obtain free automatic releases and more. Also, if you change your mailing address or email anytime in the future, please update your registration information by re-selecting Registration from the HELP menu in Dynomation-5. Thank you.

Thank you for purchasing Dynomation-5 for Windows-compatible computers from Motion Software, Inc. This software is the result of years of simulation development and programming effort, nearly twenty years of practical testing and optimization, not to mention several million of dollars of development and programming expense. Dynomation-5 was built, from the ground up, to be easy-to-use, yet it is fully capable of advanced engine-simulation analysis that will reveal how the IC (Internal Com-bustion) engine works unlike any other method of testing or analysis. You can view

Dynomation-5 is the most comprehensive yet easy-to-use engine simulation software

package ever offered to performance engine builders and enthusiasts. Dynomation-5 offers

high speed, accuracy and a robust modeling toolset.

pressure waves and mass flow that takes place inside the intake and exhaust pas-sages; you can easily change components and measure their affect on power, you can learn more about how engines work than you ever thought possible. Not only that, we are confident that you will find Dynomation-5 an intuitive, easy-to-use program that makes engine testing and analysis fun! Simply put, by eliminating the frustration that is com-mon with many other engineering-oriented simulations, you are free to play, using


your imagination to uncover power secrets for single or multiple-cylinder engines for automotive, racing, or a myriad of other applications.

WhAT IS DyNOMATION-5?

The Dynomation-5 incorporates two distinct engine-simulation models: 1) A Fill-ing-And-Emptying (FE) simulation that provides extremely fast mathematical solu-tions to engine physics, including flow analysis through commonly-used intake- and exhaust-manifold configurations, making this technique a uniquely powerful and rapid way to ballpark engine design with very good accuracy, and 2) A full Wave-Action (WA) simulation that accurately predicts the complex pressure-wave dynamics and particle flow in intake and exhaust ducting. The Wave-Action model picks up where the Filling-And-Emptying method leaves off and homes in on the best port sizes, shapes, runner lengths, header configuration and tubing sizes, cam timing and valve motion, and other engine parameters, providing unprecedented accuracy for the seri-ous engine designer and builder. By integrating these simulation technologies using a carefully-crafted Direct-Click user interface with RollUp menus, engine data is seamlessly shared by both simulation models. Power, torque, engine pressures and several other engine variables can be displayed independently, in comparison views, or in a HybridSim, where simulation results from both methods are combined, building on the strengths of each modeling technology. Youll also find hundreds of other features in Dynomation-5 that have become Motion Softwares trademarks, including: 1) rapid Iterative testing, 2) comprehensive camshaft, cylinder-head-flow, and engine-file import, 3) several built-in calculators for compression ratio, airflow conversion, rocker-arm and cam-timing math, 4) multiple-

hOW DyNOMATION-5 WORKS

Dynomation-5 is a Windows98/Me/2000/XP/Vista, 32-bit engine-power simula-tion that utilizes both Filling-And-Emptying and Wave-Action modeling technology. Dynomation-5 is a full-cycle simulation, meaning that it calculates the complete fluid-dynamic, thermodynamic, wave-dynamic, and frictional conditions that exist inside each cylinder throughout the entire 720 degrees of the four-cycle process. There are several other simulation programs currently on the market that do not incorporate this sophisticated modeling technology. Rather, they calculate the volu-metric efficiency (VE) and then derive an estimate of torque and horsepower. There are many shortcomings to this and similar techniques. The two greatest drawbacks are: 1) since cylinder pressure is not precisely determined, it is impossible to predict the pressure on the exhaust valve and the subsequent mass flow through the port when the exhaust valve opens, and 2) the inability to accurately determine the pump-ing horsepower (energy needed to move gasses into and out of the engine) from the predicted horsepower. Since Dynomation-5 incorporates full-cycle models in both the FE and WA models that include frictional and pumping-loss calculations, extensive computation is required for each power point. In fact, the program performs several HUNDRED MILLION calculations at each rpm test point throughout the power curve. This level of mathematical analysis has only been possible since the advent of the modern personal computer and its built-in high-speed, math-computation processors.

Dynomation-5 Quick Iterator TestingIterative Testing is a powerful feature of both

the Filling-And-Emptying and Wave-Action mod-

els in Dynomation-5. This screen illustrates a test that

is evaluating a series of components (over 200 dyno tests have been performed). Using this powerful tool it is

possible to automatically run thousands or even hundreds

of thousands of tests to find the best combinations.

Dynomation-5 keeps track of all the results and displays

the best matches to your test criterion.


Introduction To Dynomation-5Please Note: The Wave-Action model is much more computationally intensive than the Filling-And-Emptying model. As a result, you may notice delays of several seconds for each Wave-Action analysis to be completed (depends on the speed of your computer system).

The in-depth analysis provided by Dynomation-5 offers unprecedented accuracy over a vast range of engine designs. Dynomation-5 has been successfully used to model single-cylinder lawn mower engines, light aircraft engines, automotive engines, 2-, 3-, 4-, and 5-valve high-performance racing engines, ProStock drag-racing pow-erplants, multi-thousand horsepower supercharged, nitrous-oxide injected mountain motors, and many other engine designs.

WhAT'S NEW IN Dynomation-5

If you have used the earlier, DOS version of Dynomation (originally developed by Curtis Leaverton at V.P. Engineering) you will find Motion Software Dynomation-5 to be a substantial upgrade. Many aspects of the program have been enhanced, including the user interface, results displays, Forced-Induction modeling, multi-valve-per-port engine modeling, exhaust-system modeling, and the incorporation of a super-fast Filling-And-Emptying simulation that can rapidly ball-park engine designs. You will also be pleased to find an enormous speed increase in the Wave-Action analysis (over 100 times faster than original Dynomation versions). Simulations that would take up to 15 minutes in the past can now be done in less than 5 seconds! The display and analysis of pressure waves in the intake and exhaust ports also have been greatly improved. Click on the power/torque graph to select any rpm point; you will instantly see the status of pressure waves and mass flow at that engine speed. Drag the reticule line on the power/torque graph; the pressures and flow waves will be dynamically updated as you scan through the rpm range. This capability provides an unprecedented view of pressure and particle flow within a running engine. Another new addition is easy-to-use Iterative Testing. An exclusive feature of Motion Software simulations, Iterative Testing allows you to automatically perform thousands of dyno tests, keep track of all the results, and locate the best component combination that matches your search criterion. This is a great way to search through thousands of cams to reduce your testing in the Wave-Action model to just a handful of choices. Dynomation-5 also offers many additional improvements. You will find new com-bustion-chamber analysis, improved ignition-timing prediction, improved multiple-valve-per-port engine modeling, more stable operation especially with forced induction and very high-speed engines and several other enhancements. You will also find a new Rocker-Math feature that reveals the actual changes that occur when lash or rocker-ratio are modified, improved Roll-Up menus that let you focus on the components you are testing, better integration between the FE and WA models, improved cam-profile modeling and more. But most important is enhanced support. Motion Software, Inc., development staff

Dynomation-5 Requirements

Here are the basic hardware and software requirements for Dynomation-5: An Windows-compatible PC with a CD-ROM drive. A USB Port for the Security Key (see page 14) that is required to run Dynomation-

5. A minimum of 256MB of RAM (random access memory) for Windows98/Me;

512MB for Windows2000/XP and 1GB for Vista. More memory than this will improve program performance

Windows98/Me or Windows2000/XP/Vista (32-bit). Note: Windows95 is not sup-ported.

A video system capable of at least 800 x 600 resolution. Recommend 1280 x 1024 or higher to optimize screen display of engine components and graphics.

A fast system processor (2GHz or faster) will improve processing speeds; espe-cially helpful for Wave-Action and Iterative testing. However, Dynomation-5 will operate on any Windows98/Me/2000/XP/Vista system, regardless of processor speed.

A mouse/mousepad/trackball is required for cursor movement and component selection.

Any Windows compatible printer (to obtain dyno-test printouts).

SySTEM REqUIREMENT DETAILS AND OThER CONSIDERATIONS

Windows98/Me/2000/XP/Vista: Dynomation-5 is designed for Windows98 through WindowsXP (all 32-bit versions) and Vista (32-bit version). Make sure to install all the latest service packs and updates for both Windows and for Internet Explorer (use the Microsoft Windows Update feature available in the Start Menu or visit www.microsoft.com to locate updates and service packs for your operating system). We recommend that you run Dynomation-5 on a Windows2000/XP/Vista machine. These operating-system versions are the most sophisticated and reliable.

Video Graphics Card And Monitor: An 800 x 600 resolution monitor/video card are required to use Dynomation-5. Systems with 1024 x 768 resolution (the typical resolution for 17-inch or larger Monitor/LCD displays) provide more screen real estate, and this additional display space is very helpful in component selection and power/pressure-curve analysis. Screens of 19-inches or larger with 1280 x 1024 resolution are optimum for Dynomation-5.

Note: See FAQ on page 266 for help in changing the screen resolution of your system and monitor.

System Processor: Dynomation-5 is extremely calculation-intensive. Over 100 million


mathematical operations are performed for each complete power-curve simulation. While the program has been written to optimize speed, a faster processor will improve data analysis capabilities. Furthermore, Dynomation-5 incorporates powerful Iterative Testing that can perform an analysis of hundreds or thousands of simulation runs. To reduce calculation times and extend the modeling capabilities of the program, use the fastest processor possible.

Mouse: A mouse (trackball, or other cursor control device) is required to use Dynomation-5. While most component selections can be performed with the keyboard, several operations within Dynomation-5 require the use of a mouse.

Printer: Dynomation-5 can print a comprehensive ProPrint Dyno-Test Report of the simulated dyno engine on any Windows-compatible printer. If you use a color printer, the data curves and component information will print in color (see page 214 for more information about Dynomation-5 printing capabilities).

screen prompts presented by the program installer. If you have any diffi-culty during installation, please review the following important points and installation steps:

Make sure all other applications are closed before you begin this installation. The best way to do that is to restart your system, then begin this installation before you start any other programs. If other programs are using system resources during Dynomation-5 installation, your computer may appear to lock-up when in fact, another application (hiding in the background) has taken focus away from the Dynomation-5 program installer.

Make sure that you have sufficient memory to install/run Dynomation-5: For Windows98/Me have at least 256MB of memory, for Windows2000/XP at least 512MB of memory, and for Vista at least 1MB of memory is required (see page 12 for more information about system requirements). Note: You must have Administrator Rights to properly install Dynomation-

5 under Windows2000/XP/Vista. Administrator Rights are also required to receive automatic updates over the Internet.

During installation, allow the installer to place program files within the sug-gested directory (C:/Dynomation5). This will ensure trouble-free operation now and during the installation of future upgrades and enhancements.

b) Another dialog box will ask for permission to install a Camtasia Codec on your system (needed to display tutorial and video help files). Choose Install to begin the codec installation.


Installing & Starting Dynomation-5b) A final dialog box will guide you through the installation of the HASP driver

for the Dynomation-5 USB security key (discussed in the next section).After the USB key driver has been installed, the basic Dynomation-5 program installation is complete.

Installing The USB Security Device

9) Install the USB Security Key (the small USB plug supplied with Dynomation-5) into an available USB port on your computer. This key is licensed to you, the purchaser of this software, and will allow you to run Dynomation-5 on any of your computer systems.

You are licensed to install Dynomation-5 on as many computers as you wish, however, Dynomation-5 will only run on one system at a time; the computer that has the Security Key installed in a USB port.

Note: If you do not have an available USB port (your computer must have at least one USB port to use Dynomation-5), you can install a USB Card or Hub to extend the number of available USB ports. The Dynomation-5 Security Key will function properly in USB ports directly attached to the computer or on a USB Hub.

Solving USB Security Key Issues: If Dynomation-5 displays an error message

that the Security Key is missing, here are some quick steps you can follow to isolate and correct this issue (more detailed information is provided in the FAQs on page 266 and on our website www.MotionSoftware.com):a) Make sure the Security Key is, in fact, properly connected to a functioning USB

port on your computer or has been plugged in a USB hub that is connected to your computer. If you plugged the Key to a hub (rather than into a USB port on the computer), try connecting it directly to a port on your computer system. Note: The Security Key contains a small LED that lights up when it is properly connected and it has located the correct software drivers (these drivers are normally installed during Dynomation-5 installation, see step c below).

b) Make sure your USB port is functioning correctly by disconnecting all other USB devices from your system. Then connect the Security Key (try a port you haven't used). If that works, try a different USB device in the port that did not work to determine if that port is defective.

c) Try reinstalling the Security Key drivers. Open the Windows Start menu, select All Programs, then choose Motion Software Simulations, Dynomation-5 Engine Sim, and finally click on the HASPUsersSetup icon in that folder. If Dynomation-5 still does not startup properly, try restarting your computer sys-tem to ensure a complete HASP installation.

d) If your computer experiencing technical difficulties, such as non-functional devices, spontaneous rebooting, numerous error messages, etc., the device drivers for our Security Key may not properly install on your system. You must have a stable computer system and a clean, virus-free Windows installa-


Installing & Starting Dynomation-5tion to properly use Dynomation-5.

e) Try installing Dynomation-5 and the Security Key on another computer system to determine if your computer is at fault.

f) Refer to additional information on Security Key issues located in the FAQs on page 266 and on www.MotionSoftware.com.

Installing CamDisk7

10) CamDisk7, an additional library of 6000+ camfiles (these are 10-point, not profile, camfiles), is included with Dynomation-5. If you wish to install the additional camfiles to expand the Dynomation-5 cam library, click on the CamDisk7 icon on the program installer screen (see page 14). CamDisk7 camfiles can only be installed after Dynomation-5 has been successfully installed on your system.

Starting Dynomation-5

11) To start Dynomation-5, open the Windows Start menu, select All Programs, then choose Motion Software Simulations, Dynomation-5 Engine Sim, and finally click on the Dynomation-5 icon displayed in that folder (alternatively, you can double-click the Dynomation-5 program icon that was installed on your Desktop).

USB Security Key Issues: If Dynomation-5 displays an error message indicating that the Security Key is missing or cannot be found, refer to the previous section for help.

12) When you first start the program, a Registration dialog will be displayed. Please fill in the requested information, including the serial number found on the back of the QuickStart Guide provided with Dynomation-5. Then press the Proceed button. If you have an Internet connection, your registration will be submitted to Motion Software, Inc., automatically. If you do not have an Internet connection, you will be presented with other registration options. If you do not register this simulation, you may not qualify for tech support or free updates.

Update your Registration Info: If you move or change your email address, you can update your Dynomation-5 registration information at any time by simply selecting Registration from the hELP menu in Dynomation-5, then resubmitting your updated info. Keep up to date with the latest Dynomation advances by keeping your registration information current.

Uninstalling Dynomation-5

You can uninstall Dynomation-5 by either: 1) Use the program removal feature in Windows (Start menu, select Control Panel, then Add or Remove Programs), or 2) Use the Uninstaller placed in the Dynomation-5 folder (Start menu, select All Programs, then choose Motion Software Simulations, Dynomation-5 Engine


Installing & Starting Dynomation-5Sim, and finally click on the UNInstall Dynomation-5).

Solving Installation And Operational Problems

Important Note: You can obtain technical support and program updates by visiting (www.MotionSoftware.com) or by opening the Start menu, select Programs, Motion Software Simulations, Dynomation-5 Engine Sim, then click on the Tech Support Website.

If you experience problems installing or using Dynomation-5, please review the information presented in this Users Manual, including the information earlier in this chapter, the FAQs on page 266, and check online for program updates (www.MotionSoftware.com). Dynomation-5 is a complex program; if you are not care-ful during engine-data input, these errors will generate invalid simulation results. Here are a few things you can consider before you contact Technical Support:a) If you are not getting good correlation between the Wave-Action and Filling-

And-Emptying simulation models, make sure you are using similar induction and exhaust systems. Remember, the Wave-Action model does not simulate mufflers, so if you are using other than open headers in the Filling-And-Empty-ing model, power values will not match.

b) If the cam-lobe profile that you are testing or reviewing in one of the graphs appears to reflect incorrect valve timing, make sure you are not looking at the other (high-speed or low-speed) lobe of a Variable-Valve-Timing cam setup.

c) If power values are substantially higher for the Filling-And-Emptying model, try tuning the induction and exhaust systems in the Wave-Action model. The Filling-And-Emptying simulation always assumes optimum runner and header lengths, so it often predicts near optimum power.

d) If a turbocharging system is not developing the boost or power you expect, remember that the Boost Limit in Dynomation-5 is an upper limit. It does not force a too-large turbo to spin up more quickly and generate the desired boost. Selecting the correct size turbo, turbine, and A/R ratio to obtain the desired boost curve is essential to obtain appropriate simulation results. To observe induction pressure throughout the rpm range, set either the Y1 or Y2 axis on the upper-right (rpm-based) graph to manifold pressure.

e) Remember that only the Wave-Action model uses imported cam-profile data intact. The Filling-And-Emptying model always derives valve motion from cal-culated 10-Point timing. In addition, if you are using cam-profile data in the Wave-Action model, when you change any cam specification (other than ad-vance or retard and centerlines), profile data will be discarded and the Wave-Action simulation will derive 10-Point cam timing matching the valve events you have entered. The assumption here is that since you cannot alter profile cam files (they describe a specific lobe), you can't change IVO, IVC, etc., with-out invalidating that profile. As a result, Dynomation-5 discards profile data


Installing & Starting Dynomation-5and derives 10-point timing as close as possible to the now-modified profile.

f) Carefully review all your component selections. You may find that reviewing your engine component selections helps you find to the source of the problem. Its easy to look at a component specifications numerous times and see the correct number, only to look again and find an error that was in plain sight.

g) If you are certain that you have found an outright bug in Dynomation-5, we are anxious to hear from you. It is our firm intention to make sure this engine simulation stays one of the most sophisticated, stable, and useful develop-ment tools available to the engine builder and enthusiast.

Drag the reticule across the Port Velocity graph to view port flow data at various engine speeds. Click on the Port Velocity graph to display a reticule line; the exact data values at the reticule intersection will be displayed in the SimData Window (see 12, above).

14) The Port Pressures (pressure is the default display) middle graph displays the port pressures (calculated at a location just under the valves) at various rpm and crank-angle values. Click on the top horsepower/torque graph to display a reticule line and establish the rpm for viewing pressure data. Drag the reticule across the Port Pressure graph to view port flow data at various engine speeds. Click on the Port Pressures graph to display a reticule line; the exact data values at the reticule intersection will be displayed in the SimData Window (see 12, above).

15) The various graphs display horsepower, torque, port pressures, flow rates, valve lift, and more for the currently-selected engine. These graphic displays can be customized to display additional data in many formats using the Graph Options Box. To display the Options Box, right-click on any graph; reassign the X, y1 and y2 curves to any of the data sets provided in the submenu. Optimize func-tions quickly setup curves for best visual resolution. quickCompare (see page 171) will quickly setup sim "baselines" to help evaluate changes or establish comparisons with other engine files. Finally, use the Properties choice at the bottom of the menu to assign custom axis values and setup multiple engine-to-engine comparisons.

SimData Window

The Crank-Angle SimData Window displays the exact values of port pres-sures, flow rates and other simulation

data at various rpm and crank-angle values. Click on the rpm graph or any

crank-angle graph to display a reticule line (see 17, below). As you drag the reticule across the graph, exact data

values at the reticule intersection point will be displayed in the SimData Win-

dow (open the SimData Window from the Tools drop-down menu).


Program Overview

1) The horsepower And Torque (displayed by default) top graph displays engine output throughout the simulation rpm range. Click on the graph to display a reticule line (this also fixes the rpm for viewing pressure/velocity data on either of the crank-angle graphs when using the Wave-Action or HybridSim models). The underlying engine power data at the reticule intersection can be viewed in the SimData Window (see 12, above and photo on previous page). In addition, exact horsepower and torque values are displayed in the data tables available by clicking the Table Tab or the ProData Tab at the bottom of the graph window.

17) Each of the four graphs (the fourth is located under the Component Categories; to view this graph, click on the Graph Tab at the bottom of the left window) incorporate a Reticule Line that appears when you click on the graph. You can drag the Reticule Line left and right, across the graph between the lowest and the highest test rpm (for the horsepower and torque graphs), or between 0- and 720-degrees of crankshaft movement (for the middle and lower port pressure/ve-locity graphs). The exact values of the underlying data at the reticule intersection are displayed in the SimData Window (see 12, above).

18) The Main Program Screen incorporates Windows Size Buttons. These buttons provide standard maximizing, minimizing, and closing functions common to all Windows applications. Refer to Windows documentation for more information on the use of these buttons.

19) The Pop-Up DirectClick Component Menus allow the selection of compo-nents and specifications within each of the Component Categories. Click on any component specification to open its menu. The menu will close when a selection is complete. If you wish to close the menu before making a new selection, click

Direct-Input vs. Menu-Input Component Categories

Component menus fall into two categories: 1) Those that accept direct user input (custom values) and, 2) those that only accept a selection from their attached drop-down menu. For example, the Number Of Cylinders menu in the Short-Block category will accept direct input (any value from 1 to 12), but you can also select common cylinder combinations from the drop-down menu. When a menu supports direct-data entry, the component-entry bounding box will have a white interior (see photos). On the other hand, the Pressure Drop menu associated with the Total Induction Flow Rate, will only accept one of the two selections

Program OverviewDirectClick Component Menus

The DirectClick Component Menus contain components and specifications

for each Component Category item (Combustion-Chamber types are shown here). Click on any component specifi-cation to open its menu. The menu will close when a selection is complete (or

accept the current selection by clicking on the green ). If you wish to close the

menu before making a new selection, click the red X next to the drop-down

box, click anywhere outside the menu, or press the Escape key until the menu

closes.

Fields Accepting Direct Input

Fields Not Accepting Direct Input

Component fields that support direct nu-meric entry have white bounding boxes (left). When the only selection possible is a choice from the drop-down menu, the bounding box will have a gray interior (below).

Program Overviewfrom its attached menu (1.5- or 3.0-inHg). The data entry box within Component Categories that only accept menu inputs have a light-gray interior (as opposed to white).

Note1: Almost all custom-input categories include an attached menu from which common data inputs are also provided.

Note2: Data entry into any component field is limited to values over which Dynomation-5 can accurately predict power. The range limits are displayed in the Range Limit Line within the Status Bar at the bottom-left of the Main Program Screen (see page 26). If you enter an invalid number, Dynomation-5 will sound the Windows error tone and wait for new input.

Keyboard Selections And Shortcuts The following keyboard speed tips will help you make the process of data entry and what-if testing more efficient. None of these operatio ns are essential, and if you are more comfortable using only a mouse, you can skip this section.

Cursor Arrow Keys Move Reticule LinesYou can move the reticule lines on any of the graphs in small increments by using the Cursor Arrow keys. First, click on a graph to "select" it, then use the Right-Arrow key to the move the reticule line to the right; use the Left-Arrow key to move it to the left. If you hold the ShIFT key, the increment of movement on the crank-angle graphs increases to 10-degrees.

Opening Menu-Bar MenusPress and hold the Alt key, then press the F key to highlight and open the File menu (in the Menu-Bar at the top of the program screen). Use the cursor-arrow keys to move through menu selec-tions; press the Right-Arrow key to open submenus and the Left-Arrow key to close submenus. With any menu open, you can also use the right-and-left arrow keys to activate other menu-bar menuse.g., Edit, View, Simulation, etc. When you have highlighted the menu selection you wish, press Enter to accept the selection. Press ESC (the escape key) repeatedly to close the menus without making a selection. Note: You can also use the Alt key combination with the E, V, S, U, T, W, and h keys to directly open the other program drop-down menus.

Moving Through Component FieldsAfter you have selected any field within a component category, you can press the TAB key to move the highlight from field to field. Tab key-presses will not open fields for data entry, but rather will move the highlight focus from field to field. Tabbing always keeps field highlight-ing within the current category.

Note: The Shift Tab key combination will move the highlight box backwards to the previous component field.


Program Overview Entering Data In Component FieldsWhen the highlight box resides on a

field in which you wish to enter data, press the Enter key once to convert the highlight to a data-entry bounding box. Then key in your data (or open the drop-down menu and make a selection), finally press the Enter key again to close the bounding box and accept the data. To move to the next field, you can press the Tab key, or you can again press Enter. Using Enter instead of the Tab key not only moves the highlight to the next field, but also opens the data-entry bounding box in one step. So by pressing keys in the Enter, Enter, (data entry), Enter Enter fashion, you can quickly enter data in all component fields within a selected category.

ThE MEANING OF SCREEN COLORS

The colors used on the component-selection screen provide information about various engine components and specifications. Here is a quick reference to screen color functionality (these descriptions apply to the Basic Blue color scheme; the default selection in the View menu, however, while the colors are different in other color schemes, the way colors are used to differentiate component fields is the same):

White: Most engine component names and field labels are displayed in white. This indicates that these fields contain data that is required in order for a simulation to be performed (both Wave-Action and Filling-And-Emptying).

Orange: Data in component fields that is displayed in orange indicates that these values are automatically calculated by program and cannot be directly altered. For example, the Plenum Configuration in the INDUCTION category

Screen ColorsThe colors used on the component-

selection screen provide information

about what fields are currently being used and whether

you can modify these components.

This is the Basic Blue (default) color scheme; Cyan indi-cates components that can be modi-fied, while Orange

are display-only fields.


Program Overviewis determined based on the current manifold selection.

Light Blue (Cyan): All engine component category fields that are displayed in light blue are components/specs that can be changed. For example, the Bore field in the ShORTBLOCK category can be modified and is displayed in Light Blue.

Note: Both the Wave-Action and Filling-And-Emptying simulations are performed when HybridSim is selected, as the power/torque displays are a combination of the results from both simulation methods (see page 42 for more information).

Building An Engine Using The Filling-And-EmptyingAnd Wave-Action Models In Dynomation-5

The most common method of starting an engine-design project in Dynomation-5 is to assemble a test engine from component parts. In this tutorial, do a quick engine build using the Filling-and-Emptying (FE) simulation model. Then, after we have obtain initial power predictions, we'll switch to the powerful Wave-Action (WA) simulation and fine tuning component selections. Follow along with these steps for a quick look at how to make component selec-tions and build an engine from scratch:

1) If necessary, start Dynomation-5; if it is already running, select New from the File menu. All component categories begin empty, as indicated by a string of asterisks ( **** ) next to each incomplete component field.

2) Move the mouse cursor into the Simulation category and click the Filling-And-Emptying Model radio button, activating the FE simulation method.

Note: For the time being, well skip the Wave-Action and Environmental compo-nent groups inside the Simulation category.

Simulation: Simulation Model Radio Button: Filling-And-Emptying Model

3) Next, move the mouse cursor into the Shortblock component category and click the left mouse button on the asterisks in the highlighted Short Block field.

4) When the component-menu bounding box appears (see photo, next page), click on the symbol to open the Short Block
