The engine is not working properly and Solutions

The engine is not working properly
2.1, black smoke
Possible causes:
1) clogged air filter serious
2) Fuel grade does not
3) exhaust back pressure too
4) fuel pump failure
5) oil Tsui killed
6) lack of engine cylinder compression force
Treatment:
1) Check whether the air filter failure
2) Inspect the fuel quality
3) Check the fuel injection pump fuel supply readjust
4) Check the fuel injector nozzle atomization condition
5) Check the cylinder compression force is normal
2.2, take the blue smoke or white smoke
Possible causes:
Improper 1) oil grades to choose from, the oil level is too high
2) Engine temperature is too low
3) piston ring wear, turbocharger failure
Treatment:
1) Check the oil is too thin, check whether the oil level is within the prescribed range
2) Check whether the engine is running at a low temperature for a long time
3) Check the piston ring and cylinder gap and piston ring groove clearance turbocharger is working properly
2.3, running instability
Possible causes:
1) or poor air passage
2) fuel pump or fuel injector nozzle malfunction
3) partially clogged air filter
Treatment:
1) Check the oil, joints are loose, filter clogging
2) Check the oil pump injection timing, the pump rack is active and flexible, oil nozzle atomization case
Clean condition 3) Check air filter core
2.4, the engine abnormal sound
Possible causes:
1) improper fuel or fuel poor choice
2) incorrect when injection
3) injectors failure
Treatment:
1) Check the fuel or heavy grades of diesel fuel plus reliable restart
2) Check the injection timing
3) Check the injectors are working correctly
2.5, lack of engine power
Possible causes:
1) oil line poor
2) high-pressure pump is not working properly
3) oil nozzle is not working properly
4) air system blockage
Treatment:
1) Check the oil supply is smooth, leak
2) Check and adjust the high-pressure pump
3) Check and replace injectors
4) Check, clean or replace the air filter
2.6, the oil pressure is too low, too high
Possible causes:
1) the oil viscosity is too low or too high
2) Pressure Gauge allowed
3) The oil filter blockage
Treatment:
1) Check whether the correct grade of oil
2) Replace the pressure gauge Retry
3) Check or replace the oil filter
2.7, the water temperature is too high
Possible causes:
1) exhaust cooling system disorders
2) injection time allowed
3) prolonged overload
Treatment:
1) Check the pump is working properly, whether the thermostat opens
2) Check the external tank is blocked, the fan belt tightness
3) the injection timing correction
4) Check the load is reasonable
