1. The air filter is not clean
An unclean air filter will cause increased resistance, reduced air flow, and reduced charging efficiency, resulting in insufficient engine power. The diesel air filter element should be cleaned or the dust on the paper filter element should be cleaned as required, and the filter element should be replaced if necessary.
2. Exhaust pipe blocked
A blocked exhaust pipe will cause the exhaust to not flow smoothly and reduce fuel efficiency. Motivation drops. Check whether the exhaust conductivity is increased due to excessive carbon deposits in the exhaust pipe. Generally, the exhaust back pressure should not exceed 3.3Kpa, and the carbon deposits in the exhaust pipe should be removed regularly.
3. The fuel supply advance angle is too large or too small
If the fuel supply advance angle is too large or too small, the fuel pump injection time will be too early or too late (if the fuel injection time is too early, the fuel will not burn fully, if the injection time is too late, white smoke will emit, and the fuel will not burn fully), causing the combustion The process is not at its best. At this time, check whether the fuel injection drive shaft adapter screw is loose. If it is loose, re-adjust the oil supply advance angle as required and tighten the screw.
4. Piston and cylinder liner are strained
Due to severe strain or wear of the piston and cylinder liner, as well as increased friction loss due to gumming of the piston ring, the mechanical loss of the engine itself increases, the compression ratio decreases, ignition is difficult or combustion is insufficient, the lower air charge increases, and leakage occurs. Severe anger. At this time, the cylinder liner, piston and piston rings should be replaced.
5. The fuel system is faulty
(1) Air enters or blocks the fuel filter or pipeline, causing the oil pipeline to be blocked, insufficient power, and even difficult to catch fire. The air entering the pipeline should be removed, the diesel filter element should be cleaned, and replaced if necessary.
(2) Damage to the fuel injection coupling causes oil leakage, seizure or poor atomization, which can easily lead to cylinder shortage and insufficient engine power. It should be cleaned, ground or replaced in time.
(3) Insufficient fuel supply from the fuel injection pump will also cause insufficient power. Parts should be checked, repaired or replaced in time, and the fuel supply volume of the fuel injection pump should be readjusted.
