In summer, cars are closed for two or three days. What's the matter if the door won't catch fire again?

The temperature is high these days, and the problem of ignition is back. The specific situation is that the car stops for about two hours, the sun is exposed, there is no shelter at all, the cold car starts, and the starting motor keeps turning, but it can't catch fire. Many experiments have found that this happens when exposed to high temperature. I thought about it myself. At high temperature, gasoline volatilizes seriously. Is it because too much oil and gas enters the engine compartment and causes suffocation and ignition? So what is the device to control oil and gas? Baidu searched a lot of information, and finally located on the carbon canister device, and went to 4S to replace it on Saturday.

Supplement: In addition to the carbon canister, the oil pump may also cause ignition difficulties. If it is difficult to ignite the car after it has been parked for a long time in cool weather (for example, overnight), it is recommended to go to 4S and let them directly test the oil pressure after the car cools down. If the oil pressure is not up to standard after the car is cold, it may be the problem of the oil pump. Because the oil pump leads to insufficient pressure in the oil supply pipeline, it is difficult to ignite when the car is cold! It seems that the problem of oil pump has gradually become the mainstream ignition problem of S6.
