The net in front of the car is called the car net or car grille, water tank guard, etc. Grille, also known as car front face, ghost face, grille and water tank guard, etc. Its main function is the air intake and ventilation of water tanks, engines, air switches, etc. , to prevent foreign objects from damaging the internal components of the car during driving, and to show beauty and individuality.
As a window that delivers air to the engine, the air intake grille is usually placed at the rear of the car grille and the front of the engine compartment. Its main function is to dissipate heat and bring air into the engine. Under normal circumstances, the front door of the car is always open, all passengers are here, and the outside air can enter at will.
This means that during cold driving, the water tank with a lower temperature has to be cooled again with external air, so the water temperature rises slowly and the engine takes longer to enter the optimal operating condition. This makes the heating effect of many models slow down and greatly reduced in winter.
In CTCC competitions, the left side of the center grid of many racing cars is blocked, precisely to allow the racing engines to reach the best working temperature and working condition in the shortest time, thereby performing better . A long time ago, some old models also used the method of hanging cloth curtains to achieve this effect.
