Does engine backfire affect the engine?

Engine tempering has an effect on the engine: 1. If there is air leakage in the intake system of the engine, it will lead to more intake air, but the ECU of the engine can't supply oil according to the actual intake air, which will lead to tempering. Technicians can use a vacuum gauge to measure the pressure of the air intake system to judge the fault point; 2. If the oil pressure of the oil pump is low or the gasoline filter element is blocked, the actual fuel injection quantity of the automobile will be reduced. The mixture is still too thin, and the throttle will still backfire. You can measure the pressure of the oil pump with an oil pressure gauge. If the pressure is normal, the gasoline filter should also be replaced. Of course, before testing the oil pump, replace the gasoline filter element. 3. Maintain normal oil level: when the oil quantity is insufficient, it will not only accelerate the deterioration of engine oil, but also cause the burning of parts due to lack of oil; On the contrary, excessive engine oil will run into the combustion chamber along the gap between the cylinder wall and the piston ring, causing the engine to burn oil. In addition, the oil level is too high, which increases the stirring resistance of oil, fuel consumption and wear.
