Common Faults and Repair Methods of Engine

Number Fault Check

2 Idling

unstable

1. Pressure reducer seals did not seat well (reseal)

2. Check the tightening screw of the mixer to see whether it is loose

or not, check all of the connections between the gas inlet pipe and

mixer for leaks.

3. Check xed bolt on speed motor to see whether it is loose or not

4. Check the LPG/NG pressure to see whether it is normal or not

5. Check the screw of pressure regulating valve to see whether it is

loose or not

6. Check the LPG tank surface to see whether it has frozen over

3 Engine will not oper-

ate standby

1. The top dead center signal of cylinder one is not correct

2. Speed signal is not correct

Elimination method: check or replace the sensor

3. Temperature of pressure reducing valve is too low
