Engine works abnormally

2.1 Black smoke emission

Possible reason:

1) The air filters are seriously jammed.

2) Wrong fuel oil.

3) Exhaust pressure higher than standard.

4) Oil spurting pump failed.

5) Oil nozzles are jammed.

6) The engine jars compression ability inadequate.

Disposal method:

1) Check up whether or not the air filter lost efficacy

2) Check up the oil quality.

3) Check up oil supply capacity of spurting pump and adjust the supply.

4) Checking up oil nozzle condition (fuel pulverization)

5) Check up whether or not the air cylinder compresses power is still normal.

2.2 White or blue smoke emission

Possible cause:

1) Lubricating oil is chosen unsuitably or lubricating oil overtops normal level.

2) The engine temperature is lower than rated working condition.

3) The piston rings wear out or the supercharge ware lost efficacy.

Disposal method

1) To check up engine lubricating oil is right and control lubricating oil in regulation scope.

2) Check up engine is under low temperature.

3) Check up the clearance between the piston rings and jars, as well as the clearance between piston rings and ring slots, check up the supercharge is working normally.

2.3 Engine runs unsteadily

Possible cause:

1) Fuel oil transfer fail or air invade into fuel.

2) Spurting pump or spurting nozzle problems.

3) Air filters are partly blocked.

Disposal method:

1) Check up fuel oil leakage or possible joint loose and whether or not the oil filter is jammed.

2) Keep the oil pump works properly and the pump rack moves nimble.

3) Check the fuel pulverization situation.

4) Keep the air filter clean.

2.4 Abnormal noise inside the engine.

Probably cause:

1) The fuel oil selection is unsuitable.

2) Fuel oil spurt time is wrong.

3) Fuel oil nozzle malfunctions.

Disposal method:

1) Checking oil name or recharging suitable fuel oil and reset the engine.

2) Keep fuel oil spurting in right time

3) Check the nozzle malfunctions.

2.5 The engine power is inadequate.

Possible cause:

1) Fuel oil transfer fails.

2) Pump work abnormally.

3) Nozzle fails

4) Air filters are blocked.

Disposal method:

1) Keep the oil transfer smoothly

2) Adjust pump and clean air filters

2.6 Engine oil pressure is crossed hanging down and overtops

Probably cause:

1) The engine lubricating oil viscosity is crossed low or overtopped

2) The pressure meter is not accurate.

3) The engine lubricating oil filter is stopped up.

Disposal method:

1) Using right engine oil.

2) Changing pressure meter and try again.

3) Changing jammed engine oil filter.

2.7 Water temperature overtop normal standard.

Probably cause:

1) Air cooling systems are out of work.

2) Wrong spurting time.

3) Overload for long time.

Disposal method:

1) Check up water pump works state and the possible block problem in water tank.

2) Adjust spurting time

3) Check out the overload state.
