The car smells like the back of the car. What is the reason?

Cars will inevitably encounter many problems in use, and many car owners will encounter the situation that engine exhaust enters the car in normal use. Engine exhaust will not only harm the lungs, but also affect human poisoning and even cause cancer. Of course, when the exhaust gas from the car engine enters the car, we should immediately find out the cause of the problem and find a solution. Next, let's discuss the causes and solutions of engine exhaust entering the car.

Causes and solutions of automobile exhaust

1. The car mixture is too thick. Incomplete combustion leads to excessive exhaust emission, so it is necessary to detect air filter element, oxygen sensor and throttle sensor.

2. When the vehicle is started during driving, the external circulation mode is enabled. In this case, 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. The engine exhaust system pipeline should be overhauled and inspected immediately.

3. Check whether the pipeline and exhaust pipe of the automobile air intake system are damaged. Implement pipeline inspection and maintenance immediately.

4. There is too much carbon in the throttle and the gasoline quality is poor. Regularly clean the carbon deposits in the throttle and cylinder, and use high-quality gasoline.

Encourage individuals not to idle on poorly ventilated roads when using cars at ordinary times. Such as garages and tunnels, which may block the exhaust pipes. These environments will basically affect the entry of engine exhaust into the cab. When the automobile exhaust enters the car abnormally during driving, close the window, check the cause, and repair the engine as soon as possible to prevent the engine from running in a closed environment.
