What is the Function of the Grille?
1 Answers
The function of the grille is to close when the engine temperature is relatively low, which accelerates the engine's warming speed and reduces exhaust emissions. Closing the grille when the engine temperature is low can also reduce wind resistance and improve fuel economy. Active grilles are automatically controlled and do not require manual operation by the driver. The active grille is located at the front of the car and consists of adjustable louvers that can control the opening angle. It maximizes the car's air intake efficiency and cooling efficiency through computer-controlled adjustments. In most vehicle models, the grille remains permanently open, which ensures that the engine receives maximum cooling power as soon as the car is started.
