Common Faults & Causes of the Engine

Common Faults & Causes of the Engine

1, The Engine Smokes White Smoke
The white smoke of the engine may be caused by the following reasons:
① The first cylinder of the engine and the injection pump timing (advance angle) are not properly adjusted.
② The worm gear is stuck at the maximum or minimum opening value.
③The pre-stroke sensor is short-circuited or open circuit (such as poor contact of the terminal).
④The throttle sensor is shorted or open.
⑤ The pre-stroke sensor is connected to the other sensor lines on the engine.
⑥MAP burned MAP does not match this model.

2, The Engine Smokes Blue Smoke
①The advance angle is too large.
②Worm gears are issued.
③The sensor is shorted or broken.
④The sensor harness is incorrect.
⑤The MAP burned by the ECU does not match the model.

3, The Engine Smokes Black Smoke
The smoke limiter is not properly adjusted.
The nozzle is poorly atomized.
Timing advance angle is incorrect (coupling slips).

4, Engine Start Failure
The worm gear is stuck in the maximum position.
Due to the problem of the sensor harness, the worm is straight to the maximum due to the stroke.
The pump is faulty or the filter is faulty.
The advance angle is wrong.
The smoke limiter has no air and the amount of oil is too small.

5, Lack of Power
The advance angle is incorrect.
The deformation of the intake pipe of the smoke limiter causes the near air to be poor.
The worm gear issuance or control program calibration error, which causes the worm gear to not reach the working opening value set by MAP.
The ECU burned out and the motor could not be controlled.

6, High Fuel Consumption
①The advance angle is not adjusted properly.
② The air intake is blocked or not nearly smooth.
③ The nozzle is poorly atomized.
④ The hand pump is not tightened after the oil is pressed, resulting in leakage of diesel.
⑤ End oil seal or “O” seal damages diesel fuel.
⑥ The axial or radial clearance of the worm leads to the reaction time lag step.

Remove the transition sleeve on the control lever assembly (1), apply even oil to the small outer circumference of the two ends of the control rod, and then insert it from the transmission end.The control rod penetrates into the end disc of the governor end, and the adjusting arm on the control rod should all penetrate into the sliding sleeve on the plunger pair, and the rotating control rod is flexible.Install the bearing end plate part (2), pull the lever out a little, and install the original transition sleeve with the original taper screw (transition sleeve, screw, control)The rods should be paired and not interchangeable.) Use the aid FD-ZH-0021 to tighten the taper screws, then rotate the lever, the lever should be flexible.Use two hexagon socket screws (3) and spring washers (4) to lock the end plate.
