Why does the engine make abnormal noises?

Engine abnormal noise is caused by engine knocking. The following is extended information about knocking: 1. Detonation causes engine knocking. 2. Detonation is an abnormal combustion phenomenon in the engine. 3. Detonation occurs during the compression stroke. 4. When the engine is in the compression stroke, both the intake and exhaust valves close, and the piston moves upward. 5. The upward movement of the piston compresses the air-fuel mixture. 6. The pressure and temperature of the compressed air-fuel mixture increase. If the air-fuel mixture ignites prematurely, it causes detonation. 7. The combustion of the air-fuel mixture pushes the piston downward while it is moving upward. 8. This affects the engine's power output and fuel economy. 9. Severe detonation can lead to connecting rod deformation or piston cracking. 10. Engine detonation is caused by using inappropriate gasoline or carbon deposits in the combustion chamber.

How to Solve the Problem of Black Smoke from Diesel Vehicles?

Detailed solutions for black smoke from diesel vehicles are as follows: 1. Replace the air filter: Excessive dust and particles in the air cause the filter element to accumulate a large amount of dirt and debris, increasing intake resistance and leading to insufficient air supply. 2. Replace the solenoid valve: Poor diesel quality can cause fuel injector clogging or wear, resulting in inaccurate fuel supply. Replacing the solenoid valve can resolve this issue. 3. Replace the fuel filter: Impurities and moisture in diesel must be filtered before entering the cylinder. If the fuel filter fails to meet standards, is used beyond its recommended lifespan, or is damaged due to quality issues, particles and moisture can enter the engine along with the diesel, causing combustion issues and damaging the fuel system. 4. Clean the fuel line: Carbon deposits can obstruct the fuel line and lead to poor fuel supply. 5. Replace damaged components: Prolonged driving can cause component wear, affecting fuel and air supply.
