The engine intake system is sealed, especially if the air filter is sealed between the engine air tubes, there is a loose, and the draft is made of dust, ore powder and other debris inhalation of the nail, forming abrasive wear, and is the early wear of the cylinder line. Main reason, it not only shortens the engine service life, but also causes deterioration of engine economics. Severe cause major accidents such as engine pull tanks, therefore, use vehicles. Regular inspection and maintenance of intake system is very If necessary, the damage to the pipe should be repaired or replaced immediately; the clamps should be re-adjusted, and the assembled should be re-adjusted to ensure that the intake system has no air short circuit, leakage.

The intake system is often prone to the following phenomena due to improper maintenance and maintenance (Table):

Fault mode

cause of issue

Intake hobby urgently deformation (absorbent)

Air filter is blocked, the hose strength is insufficient or aging

Insufficient engine (large smoke)

Air filter clogging, intake pipeline blockage

The engine is difficult to start or cannot be started, and there is a smoke discharge.

Air filter clogging, intake pipeline blockage

Engine early abnormal wear

Cracking or sealing is not strict air short circuit

The normal operation of the exhaust system has a normal operation of the intake and exhaust system. If the engine exhaust pipe is leaked to the turbine portion of the tuber, it will generate an abnormality such as exhaust noise, which will cause the speed of the transformer to drop, increase The pressure is insufficient.
