What is the reason for the smelly tail gas?

The automobile mixture is too rich and the combustion is incomplete, which leads to excessive exhaust emissions. It is necessary to check the air filter element, oxygen sensor and throttle sensor.

When the vehicle is running, the external circulation mode is turned on, so that the exhaust gas generated when the engine is running will enter the cab, and the internal and external circulation needs to be turned on and off when the vehicle is running. Check and repair the engine exhaust system pipeline in time, and then check whether the automobile intake system pipeline and exhaust pipe are damaged. Conduct pipeline inspection and maintenance in time.

Automobile exhaust pollution source

The pollution sources of automobile exhaust include carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide, soot particles and odor. Automobile exhaust, that is, exhaust gas from exhaust pipe, is the main factor of air pollution. Automobile exhaust contains carbon monoxide, nitrogen oxides and other solid particles that have adverse effects on human body, especially leaded gasoline, which is very harmful to human body.

The main hazard of automobile exhaust is the formation of photochemical smog. Hydrocarbons and nitrogen oxides react chemically under the action of sunlight to generate ozone, which combines with other components in the atmosphere to form photochemical smog. Photochemical smog can also kill trees, reduce crop yield, reduce atmospheric visibility and hinder traffic.
