How to solve the garbage smell in the car?

1. The vehicle mixer is too thick, the combustion is incomplete, and the exhaust gas emitted exceeds the standard. Need to check the air filter element, throttle sensor and oxygen sensor;

When driving in the city, the front and rear cars are very close. If you circulate outside, the outside air will come from your car. Please observe whether there is a car ahead and whether there is the smell of tail gas. If yes, turn on the internal circulation, turn on the air conditioning fan to speed up the airflow movement, and the smell is more obvious. It is suggested to open the internal circulation, and then open the window slightly to avoid the entry of exhaust gas and exchange air.

3. Clean up the carbon deposit in the throttle and cylinder, and consider whether there is a problem with gasoline;

4. After entering the car, the exhaust gas from outside the car is mixed with the accumulated odor (such as the placed fragrance, human sweat, body odor, etc.). ) and precipitation, when the air conditioner is used to turn on the warm air, the precipitation particles of odor substances will volatilize when they meet the warm and humid air flow, and will merge with the air, thus being smelled by people's sense of smell.
