Analysis of cummins diesel engine-lots of smoke when accelerating

Fault Analysis and Treatment of cummins diesel engine – a lot of smoke when accelerating
Reason 1: Air intake is not patency treatment: check the filter, pipeline and turbocharger. The supercharger should be clean and free of dirt. Be sure to make the supercharger impeller rotate flexibly.
Cause 2: Exhaust back pressure is too high treatment: in the case of load, check and correct exhaust back pressure
Reason 3: in hot climate or high altitude areas, air rarefied treatment: climate conditions have an impact on diesel engines, air rarefied into the load should be reduced
Reason 4: Air leakage treatment between the air filter and the diesel engine: check all pipe clamps, joints and gaskets. retighten
Reason 5: turbocharger compressor dirt treatment: clean or replace the supercharger, check whether there is dirt in the supercharger
Cause 6: Fuel drain valve blockage treatment: check whether the pipeline is blocked, dredge the pipeline
Reason 7: fuel oil discharge pipeline blockage treatment: check whether the pipeline is blocked, dredge the pipeline
Reason 8: Air fuel ratio controller (AFC) membrane box barometer fault treatment: check whether the barometer is damaged, degassing rail pressure is adjusted too high, whether the plunger is stuck, whether the return valve is faulty, whether fuel enters the intake pipe, etc., repair or replace
Cause 9: Inlet pipe or exhaust pipe gasket leakage treatment: check or replace the inlet/exhaust pipe gasket
Reason 10: injector injector hole blockage treatment: clean the injector and injector chamber, replace and readjust
Reason 11: The size of the injector injector chamber is not correct: adjust the injector after replacement
Reason 12: Injector injector chamber rupture treatment: Remove the injector and injector chamber. Replace ruptured fuel injection chamber. Adjust the fuel injector
Cause 13: Oil pump calibration is incorrect
Reason 14: Air fuel ratio controller (AFC) calibration is not correct: readjust accurately
Reason 15: Incorrect fuel injector flow: Check the O-seal ring of the fuel injector, fuel injection chamber, plunger filter and fuel injector flow, replace the damaged parts, and re-adjust
Reason 16: gasket leakage treatment: carry out pressure inspection to find the leaking cylinder. Replace and repair
Cause 17: Valve leakage or incorrect adjustment treatment: check for leakage, readjust the valve
Cause 18: camshaft convex Angle wear or damage treatment: check the wear situation, replace the camshaft
Cause 19: Valve and fuel injection timing is not correct Handling: re-adjust valve timing and fuel injection timing
Cause 20: Cylinder liner or piston wear or abrasion treatment: check measurement replacement repair
Reason 21: Injector needs to be adjusted: clean and adjust as needed. Check the injector chamber for wear and tear. There is nothing wrong with the plunger top. Replace or repair, readjust
Cause 22: Push rod or CAM follower cover broken or bent treatment: if damaged, replace the push rod and CAM follower cover
Cause 23: rail pressure switch (MVT) disconnected treatment: low deflagration pressure of diesel engine. Electromagnet malfunction, repair or replace
Cause 24: MVT electromagnet failure treatment: check the jet hole, gasket, O-ring and filter, etc. Replacement or repair
Cause 25: MVT piston and rack seal are damaged. Treatment: Check the air pressure, piston and seal, and recalibute
Reason 26: pneumatic solenoid valve screw (MVT) is not fastened: check whether the air pressure is correct and whether there is a broken line. Repair and tighten screws
Cause 27: pneumatic solenoid valve plunger stays in the lagging position (MVT) treatment: air pressure is not appropriate, broken line or electromagnet damage. repair
Reason 28: Air pressure pipeline leading to mechanical timing regulating machinery (MVT) is blocked:
