Gasoline is a volatile substance, the oil tank is often filled with gasoline vapor at normal temperature, and the fuel evaporation emission control system has the function of introducing the gasoline vapor into combustion and preventing the gasoline vapor from volatilizing into the atmosphere. The core component of the fuel evaporative emission control system is a carbon canister assembly. When the temperature in the fuel tank is higher, gasoline volatilizes, gasoline vapor in the fuel tank enters the carbon canister assembly through the adsorption pipeline, and the activated carbon has the function of adsorbing fuel vapor and discharges filtered air through the vent of the carbon canister. When the temperature in the oil tank is low, the oil tank is in a negative pressure state, and air is supplied to the oil tank through the carbon tank air opening. Therefore, the carbon canister vent is the only path for communicating the fuel evaporative emission control system with the outside, and the smoothness of the carbon canister vent is very important for the normal work of the fuel evaporative emission control system.
Traditional charcoal jar blow vent leads to atmosphere directly, and the charcoal jar arranges in more positions of dust such as automobile floor below, wheel casing again, just so can make impurity such as pebble, dust gather at the charcoal jar blow vent because of abominable driving environment easily, causes to ventilate smoothly even to block to lead to the charcoal jar inefficacy.
