What effect does air leakage have on the engine during intercooling?

1, power decreases, fuel consumption increases, and black smoke is emitted.

2. If the supercharger doesn't work, it will cause oil leakage at the compressor end of the supercharger. In fact, the supercharger is not damaged.

3. If the intercooler leaks seriously, sand particles may be inhaled to accelerate cylinder wear.

4. The exhaust temperature rises slightly.

5, resulting in incomplete combustion, long time will make the valve and cylinder head produce a lot of carbon deposition.

Extended data

1) sensor is used to measure the temperature of coolant, and its resistance values at different temperatures should meet the standards. If the resistance is too large, the computer will mistakenly think that the engine is in a low temperature state, thus controlling the enrichment of cold cars and increasing fuel consumption. It can also be detected by a computer decoder, and the coolant temperature value sent to the computer by the coolant temperature sensor displayed by the detector is compared with the actual coolant temperature of the engine. If there is a difference, the coolant temperature sensor is faulty and should be replaced.

2) Check the air flow meter or intake pressure sensor, and its value should meet the standard. The error of air flow meter or intake pressure sensor will directly affect the fuel injection quantity. If the test result is abnormal, replace the air flow meter or intake pressure sensor.

3) Check the throttle position sensor. When the throttle valve is at medium or small opening, turn off the full load switch. If the full load switch is always turned off or turned off too early, the computer will always focus on full load or prematurely, thus increasing fuel consumption.
