The main role of the automobile mesh is to air intake and ventilation of the water tank, engine, air conditioning, etc., to prevent damage to the internal parts of the cabin by foreign objects while driving, and to show the personality of the car in an aesthetic way. In automotive engineering, the mesh is used to cover the body of the car to allow air to enter. Most vehicles have a center mesh in the front of the car to protect the radiator and engine. Other common center grilles are located under the front bumper, in front of the wheels (to cool the brakes), up front for cabin ventilation, or on the trunk lid (primarily for rear-engine vehicles). The center grille is often a distinctive styling element, and many brands use it as their primary brand identity.
