4.check the regulator

Abnormal knocking in the motor

Possible cause

1.the oil is not suitable

2.injection at the wrong time

3.errors of the injection valve

Disposal route

1.check the number of the oil or fix more reliable diesel oil and then start

2.check the injection timing

3.check whether the injection valve is in normal

Abnormal knocking when strike the motor

Possible cause

1.abrasion of the crank shaft bearing or damage to the piston

2.the wrong spark wheel

Disposal route

1.shut the motor and contact with the Division of Customer Service in ZHONGCE

Underpowered of the motor

Possible cause

1.something wrong with the oil circuit

2.abnormal operating of high pressure oil pump

3.abnormal operating of the oil valve

4.errors of the induction system

Disposal route

1.check the oil circuit

2.adjust the high pressure oil pump

3.check and replace the injection valve

4.check,clean or replace the air cleaner element and supercharger

The oil pressure

Possible cause

1.the viscosity is too low or high

2.something wrong with the pressure gauge

3.plugging of the diesel filter

Disposal route

1.check the number of the diesel oil

2.replace the pressure gauge and retry

3.check or replace the filter
