9 The smoking limiter diaphragm of injector damaged Replace or repair
10 The air pipe of smoking limiter damaged Replace
11 Poor atomization of injector nozzle
Inspect the injection pressure, carbon deposits
on the nozzle ; adjust and repair it;
12 Poor timing for air distribution and fuel supply Inspect and adjust it
13 Insufficient high speed adjusted by the governor Examine the speed adjuster and adjust it
14 High level of oil pan Inspect the dipstick and release surplus oil
15 Cylinder gasket leaks; valve leaks
Examine the cylinder compression pressure when
the engine is warm and replace the damaged parts
16 Piston ring broken or too large gap of bearing shell Replace the damaged parts or overhaul the engine
17
Cylinder liner or piston ring are worn or
scratch the cylinder
Repair the engine
4. Great fuel consumption
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 Poor quality fuel Clean the oil tank, filter parts and oil pipe; replace the fuel
4 Leakage with fuel pipe Inspect and repair it
5
Poor atomization of injector nozzle
Inspect the injection pressure, carbon deposits on
the nozzle ; adjust and repair it;
6 Poor timing for air distribution and fuel supply Inspect and adjust it
7 Cylinder gasket leakage and poor sealing of valve
Inspect the compression pressure when the cylinde
is warm; replace the damaged parts
8 Large gap of bearing shell Inspect and repair
9 The piston is stuck in the cylinder Change the liner, piston and piston rings
10 Insufficient pressure of supercharging system Inspect and remove leakage with pipes and joints
11 Abnormal working of supercharger Inspect or change the assembly
12 Intercooler damaged, blocked or leaks Change or repair
5. Exhaust dark smoke
Reason How to remove
1 Air intake blocked or high exhaust back pressure Cleaning
2 Poor quality fuel
Clean the fuel tank, filter parts and fuel pipes; replace the
fuel;
3 Wrong timing for air distribution and fuel supply Inspect and adjust it
4 Poor atomization of injector nozzle Adjust and repair it
5 Too much fuel injected by the injector Inspect and adjust (by special workshop)
6 Insufficient pressure of supercharging system Inspect and remove leakage with pipes and joints
7 Abnormal working of supercharger Inspect or change the assembly
8 Intercooler damaged, blocked or leaks Change or repair
6. Exhaust gray or blue smoke
