In this case, you can first check the low pressure oil line. Inspection revealed that the low pressure oil line was normal. If the oil-water separator was replaced, the situation still did not improve. Later I figured that if there was a problem with the low pressure oil line, an error would definitely be reported. Next, we need to think about how to properly use the inlet pipe of the 200 kilowatt diesel generator set. After disconnecting the air flow meter, the idle speed will not drop, and the starting speed can also be increased (the speed increase is a little). slow);
Check it Check if the air filter is too dirty. Clean the air filter and take a test drive after installation. Black smoke will be emitted when you release the accelerator. After a test drive without an air filter, black smoke will still come out whenrelease the accelerator. There are still issues with other components of the intake system; I checked the compressor and EGR valve and they are all normal. When checking the air intake system, it was found that the pipe from the intercooler to the air intake pipe had completely fallen off. The problem was solved after tightening the collar.
Possible reasons include: the air filter is too dirty, resulting in insufficient air intake, the air intake flow measured by the air flow meter is low, and the ECU limits the amount of oil. After disconnecting the air flow meter, the ECU uses the air flow replacement value for fuel injection, which can increase the speed. Due to the low actual air intake, the speed increase is slow.
When the check engine light comes on and the car suddenly stalls, a certain sensor may have been shakenwas while driving and suddenly made a bad contact, causing the error light to illuminate briefly before going out.
Why does the car engine light stay on?
This is usually caused by the fuel emission system. You can start and stop the vehicle. Start and stop the vehicle three times before starting the vehicle, then check if the error light is still on. , You need to quickly go to the store to check the error code.
