What does the underbar grille do？
The main role of the front bar under the grille is to ensure the ventilation of the water tank, engine and air conditioning and other components, while preventing the damage of external objects to the internal structure of the vehicle during the driving process, and visually adding the beauty and personality of the vehicle.
The under front bar grille, often referred to as the car median or tank guard, is an important part of the front of the car. Its design mainly takes into account the following functions:
Intake ventilation and protection: The grille allows air to enter the engine compartment, providing the necessary intake ventilation to components such as the water tank, engine and air conditioning to ensure the proper functioning of these critical components. At the same time, it also prevents the damage of foreign objects to the internal parts of the carriage during driving.
Beauty and personalization: The grille, as a unique modeling element, not only has practical functions, but also increases the beauty of the car and highlights the personality. Many automotive brands use the grille as their primary brand identity, making it a personalized expression.
Reduced air resistance: Although the presence of the grille may increase some air resistance, design optimization, such as actively closing the grille, can effectively reduce the resistance in the engine compartment, thereby improving the vehicle's fuel economy and performance.
Cooling effect: The grille acts as a channel between the outside world and the engine compartment, allowing air to enter the engine compartment through it, taking away the heat of the radiator, cooling, and protecting the engine from overheating damage.
To sum up, the under front bar grille plays multiple roles in automotive design and performance, both ensuring the normal operation of key components of the vehicle, and enhancing the overall beauty and personalized expression of the vehicle.
Is the front grille cracked badly
Cracked front grille is serious.
As an important part of the exterior of the vehicle, the under front bar grille may affect the safety and aesthetics of the vehicle. If the front grille is cracked and not treated, the crack may become larger in daily driving, ultimately affecting the safety of the vehicle. Therefore, for the crack problem of the front bar under the grille, it is recommended to take corresponding repair or replacement measures.
Repair suggestions: For the cracked bumper, if the crack is not very serious, you can consider a large repair shop for thermoplastic welding, and then spray paint for repair. This method is suitable for minor damage to the bumper.
Replacement suggestion: If the intake grille (lower grille) is damaged, it is usually recommended to replace it. Because the damage of the intake grille may affect the heat dissipation and intake efficiency of the vehicle, and then affect the normal operation of the engine.
Preventive measures: In order to avoid damage to the bumper caused by small bumps, owners can choose to install auxiliary equipment such as front and rear radar, reverse image or 360° panoramic image to help better control the vehicle and reduce the possibility of collision.
To sum up, the front bar under the grille crack is a problem that needs attention, according to the severity of the crack, you can choose to repair or replace the way to deal with, to ensure the safety of the vehicle and good appearance.
How to remove the lower grille
Open the cover of the machine and remove the two screws above the grille (fastening the bumper and grille). The grille is stuck to the bumper by several plastic hooks on the half circle. Use the screwdriver to pry open the hooks and push the grille inward to take it off.
The main function of the intake grille is heat dissipation and intake. If the temperature of the engine radiator is too high, the fan will automatically start auxiliary heat dissipation when the natural air intake alone cannot fully heat dissipation. When the car runs, the air flows backward, and the direction of the fan air flow is also backward, and the air flow of the temperature rises after the heat dissipation from the position behind the engine cover near the windshield, and under the car (which is open) flows backward, and the heat is discharged.
The intake system includes an air filter, an intake manifold and an intake valve mechanism. After the air is filtered out by the air filter, it flows through the air flow meter, enters the intake manifold through the intake port, mixes with the gasoline emitted by the injection nozzle to form the appropriate proportion of oil and gas, and is sent into the cylinder by the intake valve to ignite combustion and generate power.
