How to Deal with Excessive Exhaust Gas from a Car Engine?

[OHope]

Methods for handling abnormally excessive exhaust gas: If the exhaust gas is abnormally excessive, the solution is to take the car to a repair shop for inspection and maintenance. Car owners should promptly visit a repair shop for a check-up to prevent more serious faults. Common causes of excessive exhaust gas formation: 1. Incorrect adjustment of fuel injection timing: If the fuel injection timing is too late, the fuel cannot be completely burned, resulting in the emission of large amounts of black smoke. 2. Excessive gap between the cylinder and piston: Too much engine oil enters the cylinder, especially during splash lubrication, where a significant amount of oil seeps into the cylinder. 3. High-temperature gas from the cylinder leaks into the oil pan: This causes the engine oil to deteriorate, become contaminated, and thin, affecting lubrication efficiency and leading to excessive exhaust gas. 4. Severe wear of piston rings or cylinder liners: This results in poor sealing between the piston and cylinder liner, ultimately causing severe exhaust gas emission from the car's side breather, insufficient power in diesel engines, and possibly blue smoke emission.
