Why is the exhaust fume coming out of the car very choking?

The exhaust pipe is rusty, resulting in damage, and a large number of harmful gases are discharged from the exhaust gas.

The exhaust gas contains hundreds of different compounds, including solid suspended particles, carbon monoxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides.

The combustion is not good, maybe the three-way blower is a little blocked.

1. The problem of fuel, the fuel filled does not meet the standard, gasoline contains a large amount of sulfur, lead and other mineral elements, which will produce a large amount of sulfur dioxide and other relatively choking taste.

2. Serious burning of engine oil, poor sealing of the vehicle engine, will lead to serious burning of engine oil, and the exhaust pipe will produce a large amount of smoke, resulting in a relatively choking odor. This kind of vehicle needs to overhaul the engine and replace the four sets to ensure the sealing performance in the cylinder.

3. There is a loophole in the position of the connection between the muffler and the body, which causes a large amount of smoke to enter the cab from the damaged position, resulting in a choking smell. The vehicle needs to be lifted to find the damaged location for repair or replacement.

What causes car exhaust choking? The reasons for choking automobile exhaust: 1. When the three-way catalytic converter fails or is blocked, it cannot effectively filter the exhaust gas; 2. When the cold engine is started, in order to reach the working temperature in a short time, the engine will generally spray a thick combustible mixture, so the exhaust smell will be relatively large when the cold engine is started, which is a normal phenomenon; 3. When the concentration of combustible mixture in the engine is too high, the engine cannot fully burn gasoline, which will lead to carbon deposition in the engine, resulting in a strong exhaust odor; 4. Add to poor quality fuel, when the fuel contains more impurities, it is not conducive to automobile emissions, so you should try to choose a regular state-run gas station when refueling.

If the car exhaust emissions exceed the standard, it is easy to emit a choking odor, under normal circumstances, it is rare for people in the cab to smell this kind of smell, if the cab can smell the smell of exhaust choking, it should be dealt with in time, let's learn about the specific method.

1. The exhaust gas of the car cab chokes people, it is likely to be because of the serious burning of engine oil, the sealing of the vehicle engine is not good, and the large amount of smoke generated by the exhaust pipe will have a very choking taste.

2. It may also be because the fuel filled does not meet the standard, gasoline contains a large amount of mineral elements such as lead or sulfur, resulting in a large amount of sulfur dioxide and other relatively choking taste.

3. If there is a loophole in the position of the muffler connected with the body, a large amount of smoke will come out of the damaged position into the cab, and there will be a choking smell.

It's time to clean the throttle and injectors. Replace an air filter, and a gasoline filter. And that's it.

Refers to cold or hot starts! If it is a cold start is normal, the cold car start temperature in the combustion room is low, and the best combustion effect cannot be achieved, so it will be good after the idle speed is stable! If it's a hot car, check the gasoline and three-way catalysis that you want to add!

There is also a first floor is pure, what does the exhaust pipe choke have to do with the throttle, and the gasoline filter is changed, thanks to what you said!

If you have a diesel car or a gasoline car, if it's a gasoline car, you have to fix it.

It may be the phenomenon of burning engine oil, and the oil enters the combustion chamber from between the cylinder wall and the piston, and the exhaust gas becomes odorous.

Wear a mask.

Basic information on automobile exhaust:

Now we talk about exhaust gas, which refers to car exhaust, that is, the exhaust gas that the car exhausts from the exhaust pipe. Vehicle exhaust is another major contributor to air pollution, and vehicle exhaust contains carbon monoxide, nitric oxide and other solid particles that have adverse effects on the human body, especially leaded gasoline, which is more harmful to the human body.

Chinese name: automobile exhaust.

Foreign name: automobile exhaust Hazardous substances: solid suspended particles, carbon monoxide, lead, etc.

Emission standard: At present, it is the national IV standard in China.

Purification measures: Wash with catalyst or water.

Normal exhaust gas: colorless, no strange smell.

Exhaust gas type: black smoke, white smoke, blue smoke, etc.

What is exhaust gas, it is discharged in the first place, can it smell good If it is very pungent 1 The ternary Cui of your car is broken 2 The gasoline you add is not pure 3 The engine is not fully burned 4 The engine is burned oil.

Thank you for the trouble to adopt!

Answer: The exhaust odor treatment method is to use gasoline cleaning agent to clean the entire fuel system, including the intake duct, intake valve, and combustion chamber, carbon deposits and impurities deposits. The reasons for the pungent exhaust of automobiles are as follows: 1. The fuel quality is too poor

Gasoline contains too many impurities, heavy metals, moisture, etc., which are easy to cause exhaust emissions to be very smelly. 2. Insufficient combustion of mixed gas: the main reason for insufficient combustion of mixed gas is that the mixed gas is too thick, on the one hand, it will produce a large amount of carbon monoxide and free carbon particles in the cylinder, which is easy to affect the purification ability of the three-way catalytic converter, and on the other hand, part of the mixed gas that is not involved in combustion is also discharged with the exhaust gas, which aggravates the taste of the exhaust gas.

Add a little better oil.

You can buy some gasoline cleaner.

Question Okay, thank you.

When the car starts, the exhaust pipe is very choking, well, you should observe this situation again, is there any appearance of Lan Ye? If there is blue smoke and it is particularly choking, then your car should burn engine oil and should go to a professional car repair shop to repair it.
