The exact name of the car grille is the middle grille, water tank guard, etc. Its main function is to provide air intake and ventilation for water tanks, engines, air conditioners, etc., to prevent damage to internal components of the cabin by foreign objects during driving, and to enhance its appearance and personality. In automotive engineering, the mesh is used to cover the car body to allow air to enter. The front of the vehicle has a mesh structure to protect the radiator and engine. Other common grilles are located under the front bumper, in front of the wheels (to cool the brakes), in the front for cab ventilation, or on the trunk lid for primarily rear-engine vehicles. The center grille is often a unique styling element, and many brands use it as their main brand identity.
