【Car owner's car knowledge】The smoke from the car can be big or small, and many novice car owners are always at a loss when faced with the smoke from the car. In fact, don't panic when there is a faulty smoke, and carefully observe the smoke situation. Different faulty smokes have different solutions, so you must first know how to identify the type of smoke.
Situation 1: Black smoke
Body performance:The engine of the car vibrates greatly, the exhaust pipe emits abnormal sounds, and at the same time, black smoke is emitted, and it feels powerless when accelerating.
cause of issue:The phenomenon of exhausting black smoke is more common on carburetor vehicles. This is because the fuel injection volume of carburetor models is not controlled by the computer, but by the pedal accelerator. In some cases, too much fuel enters the cylinder and cannot be reached. It burns out of the car, which creates the black smoke we see.
Processing method:
1.Cars with carburetors are basically old now, so it is necessary to check the aging degree of carburetors and other parts frequently. Unlike EFI cars, carburetor cars need to be maintained and adjusted frequently to develop good performanc

2.For EFI vehicles, the cylinder line should be checked every 30,000 kilometers, and the spark plug should be checked every 10,000 kilometers. If there is any problem, it should be replaced in time.
Situation 2: White smoke
Body performance:It can be seen that a large amount of white water vapor comes out and the engine is not running smoothly. Even if the engine is warmed up to the normal working water temperature, there is still a large amount of water vapor coming out.
cause of issue:The white smoke may be caused by the wear of the head gasket of the engine cylinder, resulting in a certain gap, resulting in a large amount of water from the cooling system entering the combustion chamber. Water cannot be burned, and when heated, water vapor is formed, which is directly discharged from the exhaust pipe.
Processing method:
1.Check whether the engine block and cylinder head gasket are damaged, and check whether there is water in the fuel tank.
2.Check the car manual and add gasoline with the correct label in strict accordance with the manufacturer's regulations.
Situation 3: Blue Smoke
Body performance:The explosive power of the vehicle decreases, the acceleration is weak, the noise becomes louder, and the exhaust pipe emits blue smoke, accompanied by the burnt smell produced by the burning of organic oil. By checking the oil dipstick, it is also found that the consumption of oil is too large. Under normal circumstances, after each maintenance is completed, the consumption of oil should be within the normal range after driving for 7500 kilometers, and there is no need to add halfway.
cause of issue:Blue smoke is mostly caused by the internal failure of the engine, which causes the oil to enter the combustion chamber and burn. There are two common situations: the inner wall of the cylinder is scratched, the piston seal is bad, or the valve is severely worn, which will cause a gap, and the original responsible At this time, the lubricated oil will enter the combustion chamber through these gaps to participate in the combustion, and the unburnable oil will produce blue smoke when it is discharged out of the car.
Processing method:
1.For older vehicles, check the tightness of the cylinder block, piston and other components frequently. When blue smoke is found, go to the maintenance station for repair in time to prevent greater losses.
2.The oil should be added in the right amount, too much or too little is not advisable. Regularly check the oil usage. Once abnormal oil consumption is found, immediately go to a professional maintenance station for inspection.
