What is the reason for the sudden large amount of white smoke in the engine

There is a problem with the air filter. When the air filter of the car is stained and the air intake is insufficient, the exhaust pipe will have white smoke.The carburetor is out of order. There is a problem with the oxygen sensor in the exhaust pipe, causing the sensor to be unable to provide correct information. There is too much moisture in gasoline.

The engine temperature is too low, the engine fuel injection time is not timely, the oil supply system is flooded, and the fuel injection nozzle is incompletely atomized. These reasons will cause the engine to emit white smoke. White smoke indicates that the car has certain safety hazards. If left unatted for a long time, it will lead to rapid loss of vehicle parts.

The reason why the car engine has white smoke: If the car starts, white smoke comes out, which is a normal phenomenon, because gasoline contains water, and the engine is too cold, resulting in water vapor pre-cooling and liquefaction, resulting in white smoke.

The white smoke from the car engine is caused by the low temperature. In the process of the engine working, the exhaust gas discharged will condense instantly after encountering the low temperature of the outside world, and the water vapor produced will produce a large amount of misty white smoke.

The reasons for the white smoke in the gasoline engine are as follows: the moisture in the fuel is high, and there are two main factors that cause this situation. One is that the quality of the purchased fuel is very low and the water content in the fuel is high; the other is that the oil-water separator fails and the moisture in the fuel cannot be separated.

What's wrong with the smoke from the car engine

1. The blue smoke from the engine is basically caused by burning engine oil. There are many reasons for this situation, and there are roughly the following situations: I. The pressure of the oil return of the supercharger lubricant is too high. , check whether the supercharger is leaking oil and whether the return oil pipe is blocked. II. The exhaust valve is damaged, and the oil and gas cannot be separated, and it re-enters the combustion chamber for combustion.

2. The causes and treatment methods of engine smoke are as follows: Generally, white smoke will still appear when the engine of a car is hot.There may be two situations: the injection angle is small and the combustion is incomplete; the cylinder liner leaks slightly and the fuel contains water; but white smoke will appear when the cold car starts, especially when the engine is started at low temperature.

3. The main reason is the water vapor formed by cooling water rushing into the cylinder or gasoline containing moisture. Solution: When the engine is running, the exhaust pipe discharges a large amount of water vapor and white smoke. You should check whether there is water in the fuel tank, whether the cylinder pad is damaged, whether the cylinder block is cracked, whether the cylinder liner seal is good, etc.

4. There are the following situations when the car engine smokes: the air-fuel ratio is out of order, the cylinder pressure drops, the fuel injection time is too early (the fuel injection advance angle is too large), and the smoke limiter on the fuel injection pump fails, which will cause the engine to smoke.

Excuse me, what's the matter with the smoke from the car engine?

1. There are several situations in which the car engine smokes: air-fuel ratio is out of tune, cylinder pressure drop, fuel injection time is too early (fuel injection advance angle is too large), and the smoke limiter on the fuel injection pump fails, which will cause the engine to smoke.

2. The blue smoke of the engine is basically caused by burning oil. There are many reasons for this situation, roughly as follows: First, the pressure of the return oil back of the supercharger lubricant is too high. Check whether the supercharger is leaking oil and whether the return oil pipe is blocked. II. The exhaust valve is damaged, and the oil and gas cannot be separated, and it re-enters the combustion chamber for combustion.

3. The reasons for the smoke in the car are as follows: Reason 1 The combustible mixture is too thick. There is too much oil in the engine fuel. The piston ring or crankshaft oil seal is poorly sealed.There is moisture in the fuel. The spark plug is bad and the air filter is too dirty.

4. rnrn (2) There are several cases of black smoke from the automobile engine: the air-fuel ratio is out of tune; the cylinder pressure drops; the fuel injection time is too early (the injection angle is too large) will cause black smoke; the smoke limiter on the fuel injection pump fails, and black smoke will also be made when the engine accelerates sharply; exhaust brake system The work is abnormal.

5. The reason for black smoke is caused by insufficient fuel combustion or dirty air filters, poor spark plugs and other conditions, which are basically likely to affect the black smoke from the car engine.

What is the reason for the smoke from the engine

The blue smoke from the engine is basically caused by burning oil. There are many reasons for this situation, and there are roughly the following situations: First, the pressure of the return oil back of the supercharger lubricant is too high. Check whether the supercharger is leaking oil and whether the return oil pipe is blocked. II. The exhaust valve is damaged, and the oil and gas cannot be separated, and it re-enters the combustion chamber for combustion.

There are several situations in which the car engine smokes: air-fuel ratio misalignation, cylinder pressureThe decrease in force, the too early injection time (the injection advance angle is too large), and the failure of the smoke limiter on the injection pump will all cause the engine to smoke.

The main reason is the water vapor formed by cooling water rushing into the cylinder or containing moisture in gasoline. Solution: When the engine is running, the exhaust pipe discharges a large amount of water vapor and white smoke. You should check whether there is water in the fuel tank, whether the cylinder pad is damaged, whether the cylinder block is cracked, whether the cylinder liner seal is good, etc.

The reasons for the abnormal sound and smoke of the engine are as follows: if the gap between the piston skirt and the cylinder liner is too large, when the diesel engine is idle, it will make a clear and rhythmic knocking sound in the upper part of the cylinder block; excessive friction will cause damage to the parts and slight leakage of the cylinder liner.

The reason why the engine smokes: white smoke: if the temperature is lowMoreover, it is normal for the engine to have a little white smoke. If there is a large amount of white smoke, it may be because the engine cylinder and waterway burst water. The cooling water enters the engine and evaporates into steam at high temperatures. You can go to a professional repair shop or 4S store for repair and inspection.

In general, there may be two situations where there is still white smoke in the car engine in the hot state: the injection angle is small, which is caused by incomplete combustion; the cylinder liner leaks slightly and the fuel contains water; and the cold car starts with white smoke, especially when the engine starts at low temperature, but as the engine temperature rises It is normal for white smoke to disappear.
