Injector FAQ

FAQ: What are the reasons for black smoke?

ERIKC Answer:throttle failure

For engines equipped with a throttle valve, if the throttle valve is stuck or stagnated, it will not respond properly, causing poor air intake.

FAQ: What are the reasons for black smoke?

ERIKC Answer: intercooler failure

If the intercooler is broken, blocked, or lack of water (water-cooled intercooler, etc., which results in high engine temperatures, the boosted intake air cannot be cooled. As a result, the intake air temperature is too high, the density decreases, and the charging efficiency decreases. Actual entry Cylinder air will be less, resulting in lack of power and smoke.

FAQ: What are the reasons for black smoke?

ERIKC Answer: EGR-related faults

Failure of EGR or EGR valve stuck in the normally open position will result in too much exhaust gas entering the cylinder, less fresh air, and insufficient intake air.

FAQ: What are the reasons for black smoke?

ERIKC Answer: intake pressure sensor signal drift

Intake pressure sensor If the signal drifts, the ECU may receive more air than the actual air. At this time, the ECU will inject fuel according to the received signal. Actually, there is not so much air in the cylinder, which can easily cause incomplete combustion of the fuel. Black smoke. Common is the inlet pressure sensor itself failure, connector corrosion water, wiring harness connection and so on.
