The Standard in Information and Diagnostic Systems

For many years Sun has been associated as an industry leader in vehicle testing and in particular its expertise

with chassis dynamometers. The Sun RAM 3000 Chassis Dynamometer is available in two configurations 260 kW

or 360 kW both offering the same high specifications and detailed test procedures. Not only used as a method

of determining and enhancing engine performance, the chassis dynamometer can provide a platform to carry

out engine related fault diagnosis and fuel consumption analysis without leaving the workshop. The Sun RAM

3000 Chassis Dynamometer uses an Eddy current brake that offers more versatile operating possibilities.

The mobile PC platform is used to control and display the measurement results from the Sun RAM 3000 Chassis

Dynamometer. Detailed analysis can be carried out through the screen graphics or print outs.

Key Topic Fuel Consumption The practical use of this unit opens unimagined

possibilities in everyday life. Recent opinion polls

have shown that almost 20% of all drivers are

dissatisfied with the fuel consumption of their

vehicles. This problem can be controlled.

Emission tester combinations allow to simulate

various driving conditions and to draw exact

conclusions from the respective emission behaviour

concerning the high fuel consumption etc.

• Before initiating time-consuming measurements

or detail tracing, you can make clear statements

whether the fuel consumption actually is too

high or whether the customer must accept such

a weak point caused by constructional or

service conditions.

• Only in doing so can the number of errors,

which normally are approached by mere

guesswork, in a simple way be limited.

• As for example, it is possible to expose in this

way any too heavily dimensioned acceleration

enrichment or to recognise whether the cold-

start enrichment is too long active.

• It is also possible to determine in which way the

different driving styles affect consumption.

The comprehensive test programs include:The following programs are available:

1. Program P-max

Acceleration of the vehicle from start speed

up to maximum speed is done by swiftly

changing to the highest gear. After exceeding

the point of maximum performance, the clutch

is depressed and the vehicle coasts to standstill.

The loss in performance is determined whilst the

vehicle is coasting. Once completed the values

for performance, speed, and engine RPM are

indicated both numerically and graphically.

2. Program V-constant

It is possible to select a certain limit speed to

which the test stand limits the speed of the

vehicle being tested. The limit speed can also be

changed during the test so that the vehicle

performance at different speeds can be tested.

The measured values obtained by the preset

speed are indicated after finishing the test.

3. Program Power Curve

The program "power curve" allows the

automatic taking of power curves. For that

purpose, any speed range can be chosen by

selecting both a high and a low speed limit.

After starting the program, the test stand

automatically changes the limit speed in the

selected zone and records the sequence of the

measured values. Having ended the test, a

numerical and graphical evaluation can made.

4. Program Tacho Test

By means of program "tacho test" it is possible

to test the accuracy and linearity of the display at

the vehicle tachometer. This program allows to

select maximum 10 individual speeds for testing.

During the test, the test stand presets the testing

speed. As soon as this speed is reached on the

vehicle tachometer, the actual driven speed is

stored. After the test, the preset and measured

values as well as the respective deviations from

each other are displayed as a percentage.

5. Program F-constant

Program F-const is suited for the simulation

of load applications. For that purpose, it is possible

to preset a defined force the testing vehicle must drive

to in order to simulate uphill driving. The load intensity

can also be changed during the test. At the end of test,

the measured values resulting from the pre-set load

application are shown.
