ERIKC DLLA 157 P855 denso fuel engine nozzle DLLA 157P 855 denso diesel pump nozzle 093400-8550

FAQ: Failure Analysis?

ERIKC Answer: Symptoms: The starter and the engine both have a normal starting speed, but they do not catch fire; or sometimes they can catch fire after many long starts.

Cause of failure: There is air in the fuel line.

Fault nature: mechanical failure. Treatment method: The fuel pipeline exhausts air.

Failure Analysis: The State III vehicle adopts a common rail system, and the air discharged by the oil circuit is relatively difficult. Often, the operator feels that the air is excluded from the air cleanliness. Actually, it has not been thoroughly cleaned. According to the actual use situation, the oil pump return bolt should be released to discharge the air. If necessary, the high pressure fuel pipe can be loosened, and the starter can be used to drive the engine idle to discharge the air; if only the deflated screw of the fuel filter is released Exhaust air may not be easy to completely remove the air in the fuel pipeline, which is more laborious.

FAQ: Failure Analysis?

ERIKC Answer: Symptoms: The starter and engine both have a normal starting speed but do not catch fire.

Cause of failure: The timing of the pump installation is incorrect or the flywheel does not match.

Fault nature: mechanical failure.

Treatment method: Reinstall the oil pump or replace the matching flywheel.

Fault analysis: This situation usually occurs on engines that have replaced oil pumps or flywheels. For engines that have timing requirements (such as the 6DL1 State III machine), the pump installation must be correct. In addition, if the flywheel is replaced, the surrounding belt must be used. The original flywheel with signal sensing holes.
