Then it is sucked into the cab by the fan, which means that the carbon canister needs to be changed.
Many people have unplugged the engine snorkel because it always discharges oil and water and smells like gasoline.
If there is an odor in the external circulation, it may be the odor inhaled from the outside or the exhaust pipe. If the internal circulation is on, it may be that the external circulation is not closed tightly. If only the internal circulation is turned on, you should not smell gasoline, otherwise you should go to the repair shop for inspection. Generally speaking, the external circulation, if you drive, should not smell gasoline. If so, check it carefully. This is not a small problem.
There is a strong smell of gasoline in the car, so it is necessary to check the fuel pipe joint, injector sealing ring and carbon tube solenoid valve. First, check whether the fuel distribution pipe joint is marked with oil. If oil stains are found in the connector, it is recommended that you replace the clamp. It may be that the clamp has lost its function, resulting in oil stains on the joint. Secondly, there is a sealing ring on each injector. For vehicles with a long service life, the sealing ring of the injector may be poorly sealed. Then there is the failure of carbon tube electromagnetic valve or carbon tube, the electromagnetic valve is not easy to use or the service life of carbon canister is too long, which will cause the smell of gasoline in the car. Focus on these three aspects. The price of these accessories is very cheap in Auto Parts City, the sealing ring of fuel injector is tens of yuan, and the carbon canister of solenoid valve will not exceed that of 200 yuan.
Precautions:
Let the water temperature rise, then turn on the warm air.
When you are ready to turn on warm air, don't wait until the water temperature rises, otherwise it will just blow cold air. If a compressor is used, it is not cost-effective.
When using warm air for the first time, open the window to ventilate.
If it is the first time to use warm air in different seasons, don't close the window after turning on the warm air, but open a little window to let the dust and other smells blown out by the warm air run out of the car, otherwise it will be harmful to human health.
Turn on the warm air and try to use external circulation.
When using warm air, many people think that the internal circulation car is warmer. Actually, this is not good. During internal circulation, the air in the car is not circulated, and once the automobile exhaust enters the car, it will do harm to the human body.
Turn off the compressor before turning on the warm air.
In order to avoid using air conditioners with warm air, turn off the compressor to ensure that there is hot air in the water tank. This will basically not burn oil.
