What is the difference between filling up to the gun click and filling up completely?
1 Answers
The differences between filling up to the gun click and filling up completely are the remaining space, the burden level, and the process. Details are as follows: Remaining space is different: Filling up the car's fuel tank completely means there is no remaining space in the tank, while filling up to the gun click indicates that there is still some space left in the tank, and it is not completely full. Burden level is different: Clicking the gun actually protects the car's safety performance to some extent and has no impact on the car. However, filling up the tank is different. When the tank is full, it can easily cause the vent hole to become blocked. If exposed to an open flame, the car may be at risk of burning, which to some extent indicates that filling up the tank imposes a greater burden. The fueling process is different: Filling up the car's fuel tank completely is a complete process, while filling up to the gun click is not a complete process and can be divided into several stages. For example, the first gun click, the second gun click, and the third gun click. However, it is generally not recommended to proceed to the third gun click, as this situation is not conducive to the car's safety. The principle of the fuel gun clicking: Simply put, it is accomplished through a self-sealing mechanism. When the fuel level in the tank is insufficient, the air vent of the fuel gun is not blocked, and the gun dispenses fuel normally. When the fuel level in the tank is full, the air vent of the fuel gun becomes blocked, creating negative pressure inside the gun's self-control membrane. This, in turn, drives the ball and switch to disengage the gun's support plate, thereby closing the valve and causing the gun to self-seal.
