The engine is smoking. What happened?

1, causes and solutions of black smoke

Black smoke is caused by insufficient fuel combustion, unclean air filter and poor spark plug, which may basically affect the black smoke of automobile engines.

When a car emits black smoke, we should immediately observe its failure. If the black smoke is caused by oil leakage, it should be handled according to the specific location of oil leakage. If the steering power oil leaks, check the power oil tank and oil pipe before fastening.

2. Causes and solutions of white smoke

It is normal for the engine to emit a little white smoke when the climate temperature is low in winter. However, if a large amount of white smoke is emitted, it may be because the engine cylinder and waterway are flooded, which affects the cooling water entering the engine and evaporates into steam at its high temperature. This situation should be dealt with immediately, which will affect the serious damage of the engine.

Solution: Go to a professional repair shop or 4S shop for maintenance inspection.

3. Causes and solutions of blue smoke

There are many reasons for blue smoke, such as not maintaining or using unqualified engine oil immediately and not changing the engine oil for a long time, which will basically affect the blue smoke of the engine. It is also possible that the conduit in the engine compartment and its throttle valve are worn, which will affect the combustion of excessive engine oil and the generation of blue smoke.

Solution: If the maintenance is not timely and the oil quality is not up to standard, just maintain and replace the oil. However, the conduit and throttle in the engine compartment are worn, so it is necessary to go to the repair shop to remove the piston and piston ring.
