Troubleshooting

 

1. The engine fails in start

 

 

 

Reason

 

How to remove

 

 

1

 

Oil channels like inlet screen of delivery pump or hose 

blocked

Check and remove the blockage

 

2

 

Air comes into fuel system

 

Release air, inspect the joint sealing and repair

 

 

3

 

 

Injection pump error

 

Examine   the   plug,   oil   outlet   valve,   repair   or   replace
the damaged parts

 

4

 

Injector error

 

Examine the atomization and repair

 

5

 

Wrong initial angle of air distribution or fuel supply

Inspect and adjust

6

 

High pressure fuel pipe damaged or leaks

 

Repair and replace

 

7

 

 

Cylinder insufficient pressure

 

Inspect the valve sealing, gasket and the piston ring, repair or

replace;

8

 

Low ambient temperature

 

Add low temperature start equipment

 

 

2. Stops soon after start

 

 

 

Reason

 

How to remove

 

 

1

 

 

Fuel filter blocked

 

Disassemble    the    filter     and    clean    filter,    or   
replace    the element if necessary

 

 

2

 

 

Air comes into the fuel system

 

Examine the joint and sealing of the fuel pipe, if the screw 
is tightened and release the air

3

 

Fuel pump does not work

 

Examine the piston and valve of feul delivery pump, clean

 

 

or repair them

4

 

Poor quality fuel contains too much water

Clean the filter or change fuel

5

 

Low idle adjusting

 

Re-adjust

 

3. Insufficient power

 

 

 

Reason

 

How to remove

 

1

 

Air intake blocked (air filter blocked)

 

Inspect the air filter, intake pipe; clean or change the filter

 

2

 

 

High exhaust back pressure

 

Inspect    the    valve    timing,    if   the    exhaust    pipe    is   

blocked;

3

 

Insufficient pressure of supercharging system

Inspect and remove leakage with pipes and joints

 

4

 

Abnormal working of supercharger

 

Inspect or change the assembly

4.1

 

Compressor and turbine channel are blocked

Clean or replace

4.2

 

Floating bearing fails

 

Replace

 

4.3

 

Carbon,    dust    or    oil    are    accumulated    at    the   

back    of turbine and compressor

 

Wash

 

5

 

Intercooler damaged, blocked or leaks

 

Replace or repair

 

6

 

 

Fuel pipe leaks or blocked

 

Examine the pipe and joint sealing, filter, repair or remove th
blockage, replace the element

 

 

7

 

 

Poor fuel quality

 

Wash   the   fuel   tank,   filter   assembly   and   pipe,   
change   the fuel

 

8

 

Injection pump or speed governor seriously worn

Repair or replace
