The air enters the engine compartment of the car from the front grille, and the engine compartment is mostly composed of components with complex structures, and the air cannot pass through it well, thus increasing the air resistance.
Whether it is a fuel vehicle or an electric vehicle, heat dissipation is required. Taking a fuel vehicle as an example, the combustion of the engine (electric vehicle discharges the battery) generates a lot of heat, which needs to be released to the outside of the vehicle through the cooling system. Therefore, the opening of the front end of the car is necessary. The active air intake grille came into being in this situation.
The active air intake grille, installed between the radiator and the grille, can close the vents of the front grille as required. When the engine temperature is too high, the active air intake grille is opened, and the wind blowing from the front end can cool the intercooler. When the engine temperature is low, the active air intake grille is closed, and the air cannot enter the engine compartment and flow through the outer surface of the car, which brings good aerodynamics to the car.
According to statistics, a car with an active air intake grille reduces the air resistance by an average of 19 counts (saving 3% of fuel consumption) compared to ordinary cars. Of course, in addition to reducing air resistance, the active air intake grille can also achieve the purpose of fast warming up and reducing wind noise, as well as improving the working efficiency of the engine.
At the beginning of the engine startup, the temperature is low, and the active air intake grille is closed at this time, which can quickly increase the engine temperature to the working state. In addition, the active air intake grille can optimize the air flow when the car moves forward, reducing wind noise during driving.
