What is the reason for gas when opening the fuel tank cap?
1 Answers
The reason for gas when opening the fuel tank cap is: Due to gasoline being a highly volatile fuel, it accelerates evaporation after being agitated in the car's fuel tank, producing a large amount of fuel vapor. At this time, opening the fuel tank cap may result in a gas release phenomenon. The method to open the fuel tank cap is to press the fuel tank cap switch inside the car. The fuel tank cap refers to the container on the car used to store gasoline, made of stainless steel with good sealing performance. It has a circular opening about the size of a bottle cap for easy storage. Its functions include: 1. Displaying the fuel grade that the car can use; 2. Showing the standard tire pressure value; 3. Being equipped with an exhaust hole to drain rainwater.
