Air intake system structure
Figure 1 is a schematic diagram of an intake system. A complete air intake system can be divided into two parts: the engine intake manifold system and the air intake system. Air intake system - The system includes intake control valve, idle speed intake passage, bellows hose, clean air pipe, 1/4 wavelength pipe, air filter, filter element, resonant cavity, intake pipe, etc.
Intake system function
The main function of the air intake system is to deliver clean, dry, sufficient and stable air to the engine to meet the needs of the engine, and to prevent impurities and large particles of dust in the air from entering the engine combustion chamber and causing abnormal engine wear. Another important function of the air intake system is to reduce noise. The air intake noise not only affects the passing noise of the whole vehicle, but also affects the noise inside the car, which has a great impact on the ride comfort. The quality of the air intake system design directly affects the power and noise quality of the engine, and is related to the ride comfort of the vehicle. Reasonable design of muffler components can reduce the noise of subsystems, thereby improving the NVH performance of the whole vehicle.
