What is the reason for the large air intake of cars?

Too high idle motor setting causes too much idle compensation air.

There is poor air circulation in the car. In addition to the harmful gas pollution in the car, people's own smoking and body odor can also cause odor in the car. Many times, the car is a closed space with no ventilation. Even if the internal circulation and external circulation of the air conditioner are turned on, there are still a lot of pollutants in the air.

It takes many years for formaldehyde in automobile interior to volatilize, and sunlight will accelerate the volatilization, so even after many years, the car should be cleaned with a purifier.

Many brands are building their own family DNA, and the air intake grille is one of the more important elements in the front face design. Volkswagen, Audi and BMW are good examples. And of course Alfa Romeo and so on.

Step 2 protect

Many people think that the function of the grille is to protect the components in the water tank and engine compartment from foreign objects. Yes, but that's not the main function. Because the modeling of automobile will consider the problem of fluid mechanics, most flying insects and gravel on the road will be bounced off by airflow. In fact, the grille can prevent relatively large stones from entering the engine compartment and causing damage to its components.
