The white cells containing: ‘Cyl.#1’ or ‘Cyl.#2’ or … show the engine firing order(DL06/DL08 : 1-5-3-6-2-4, DV11 : 1-4-2-5-3-6)

The first column shows the ‘Elapsed time’ resulting from the operation of cylinders 2 to 6. ‘Cylinder 1’ is turned off. The second column shows similar results but with ‘cylinder 5’ turned off if engine DL08 is checked (‘cylinder 4’ is turned off if engine DV11 is checked).

The height of the six columns is the elapsed time expressed in percent of the longest of the six times recorded.

Should the deviation of any cylinder exceed 20%, a major problem is detected. Any deviation could indicate a minor problem. Typical problems could be: defective fuel spray pattern, no spray at all, scratch of the liner

This result is just for reference value

2. Main menu

▣ Case study of run up test: one an engine with an injector fault (i.e Cyl. No 2 injector).Press the ‘run up’ test button. The ECU turns No1 injector off and starts investigating engine’s speed (the engine is running with 5 cylinders only). The ECU gives signals to 5 injectors to maintain the engine running speed .The engine speed will be reduced because No 2 injector cannot generate a normal output according to our assumption. The elapsed time will be quite long.

The ECU shall turn No2 injector off afterwards. The engine speed will not be degraded because the damaged injector/cylinder is turned off. The elapsed time will be short.

The ECU shall turn No3 injector off. The engine speed shall be degraded because No 2 injector/cylinder is turned on and contributes to the time calculation again.

This test will be repeated 6 times all together. The shortest elapsed time is assigned to the column where the cylinder is damaged.

2. Main menu

Start icon- Make sure that the engine is not running, but the starter Key is in the “On” position.- The test will start after you click the ‘Start’ icon and then start cranking the engine.

Stop icon- Clicking the icon makes the test stop.

Status message - It enable you to trace the test progress.- Always follow the instructions written in the ‘message’ cell

Cranking message - Start cranking when prompted to start. - Stop cranking when prompted to stop.

Understand the graphs: ‘Compression stroke’ & ‘Expansion stroke’- It shows the elapsed time as a percentage the longest measurement time.- The software selects a time base for the compression phase & different one for the expansion phase- Assuming that the compression ratio of a cylinder is lower than the other cylinders the time needed for the compression phase is shorter, and the expansion phase longer.

How to detect Fault Injector Using Cut Off Test

if it is fault cylinder

RPM decreases No change in RPM

ECU increase fuel inj. quantity No change in fuel inj. quantity

RPM is compensated

Cut off #1 Cylinder

Normal Fault

You can decide faultiness by observing these value

60

Be aware before Cut-Off Test

During Injector Cut off test, be sure to maintain low idle rpm

After cut off test, be sure to turn off the start key switch, then wait 2~3 sec more, and start it again.(Unless restarting, you can not change RPM with accelerator pedal or throttle.)

After cut off test, Injectors which have no changes in Low Idle Control Quantity should be replacedaccording to procedures for changing injectors.

61

Injector Cut-Off Test Using E-Doctor (1/14)

• Try to check injector condition with cut off test1. Connect your e-Doctor (using gateway) to your machine.

2. Key on and start engine

3. Idling engine at low idle RPM.

4. Run e-Doctor program, and click [Connect ] icon at the left top.

Connect icon is changed to Disconnect icon while showing a message saying ‘E/G MODEL(DL08) STEP3 Communication..’ on the left bottom status bar, which means you successfully have a connection to your machine.

• Try to check injector condition with cut off test13. <Deciding Faultiness by comparing values>

Compare Low idle control quantity 1 value with the value before cut off (procedure 9).

‘Output’ value of ‘Low idle Control quantity 1’ in Output Table :

1) Increases when normal injector was cut off. (more than 5mg)

2) Has no change when fault injector was cut off. (less than 2mg)

(Refer to below example of changes of normal injectors.)

* Changes of Low idle Control Quantity value at 750 rpm

DL06 18 ±2 mg/str 22 ±2 mg/str

DL08 23 ±2 mg/str 27 ±2 mg/str

DV11 27 ±2 mg/str 33 ±2 mg/str

Above table is a example of change amounts at 750 rpm.

The value can be different depending on machine specs and conditions.

Let’s go to case study….

71



▣ Case study of cut off test : one an engine with an injector fault (i.e Cyl. No 2 injector is open condition).

Try to cut cylinder #1 off. The ECU turns No1 injector off and starts investigating engine’s speed (the engine is running with 5 cylinders only). Then, the engine speed will be decreased in a moment and recovered immediately because, the ECU gives signals to 5 injectors to maintain set engine running speed by increased fuel injection with 5 cylinders working.

The ECU shall turn No2 injector off afterwards. The engine speed will not be decreased, because the damaged (open) injector/cylinder still generate engine power (Injector open condition : Still generate power)Then, the ECU will not be increased fuel amount with 5 injector.

The ECU shall turn No3 injector off. The engine speed will be decrease by No 3 injector/cylinder is turned off and the ECU will increase fuel amount to maintain set engine running speed with 5 cylinders working

This test will be repeated 6 times all together, then you can catch up the problem injector.
