Product FAQ
FAQ: What are the reasons for black smoke?
ERIKC Answer: exhaust butterfly valve stuck
Exhaust pipe is blocked, it is easy to cause black smoke, especially when the heavy load is taken, usually with high exhaust temperature, red exhaust pipe, as shown below:
If you suspect that the exhaust is not smooth, you can disconnect the pressurized pipe after the exhaust pipe to test. If it is normal, it means that the pipeline after the exhaust pressure is blocked; if not, check the other.
FAQ: What are the reasons for black smoke?
ERIKC Answer: Injector wear, oil dripping, improper adjustment, slightly stuck fuel injector, etc.
The ECU calculates the actual fuel injection amount based on the rail pressure and power-on time. However, this actual fuel injection amount is not emitted from the injector but is a theoretical fuel injection amount. If the injector is worn, it will cause a large amount of fuel injection. Under the same rail pressure and power-on time, the fuel injected by the injector will be greater than the theoretical calculation value; if the injector fuel volume is improperly adjusted, the actual injection amount
