When a novice owner discovered that the exhaust pipe was emitting smoke, he knew that the car had failed, but he was still busy with confusion and was at a loss. In fact, in such a situation, as long as you can determine the car breakdown from the exhaust color, then you no longer have to panic. First, blue smoke Performance: The explosive power of the vehicle is reduced, the feeling of acceleration is weak, the noise is increased, the exhaust pipe emits blue smoke, and the burnt smell produced by the combustion of organic oil increases the consumption of engine oil. Cause: The blue smoke is mostly caused by internal engine failure, which causes the oil to enter the combustion chamber. Solution: Always check the tightness of the cylinder block, piston and other components; Add appropriate amount of oil, regularly check the use of oil, such as abnormal fuel consumption, timely repairs to the repair shop. Second, black smoke Performance: The car's engine is cranky and the exhaust pipe emits abnormal sound. At the same time, it emits black smoke and feels powerless when accelerating. Reasons: Most of these cases occur on carburetor vehicles. Excess fuel enters the cylinder and is then discharged outside the vehicle, causing the car to emit black smoke. Solution: Regularly check the degree of aging of carburetor and other parts, and always perform maintenance and adjustment; EFIs should inspect cylinder lines every 30,000 kilometers, check spark plugs every 10,000 kilometers, and promptly replace any problems. Third, white smoke Performance: The engine is running unsteadily, the engine warms up to normal working water temperature, there is still a lot of water vapor, and a large amount of white water vapor emerges. Cause: The cylinder pad of the engine cylinder is worn, creating a certain gap, which causes a large amount of water in the cooling system to enter the combustion chamber. Water cannot be burned, generates steam when heated, and is discharged directly from the exhaust pipe. Solution: Check the engine block and cylinder pad for any damage. Check whether there is water in the fuel tank. Check the manual of the car and add the correct number of gasoline according to the manufacturer's regulations.
