The resonator is also called the resonator, at the front end of the intake straw, generally in the front, the front down position.
The establishment of a cavity in the middle can reduce the probability of water absorption into the engine when the car tries to rush through the puddle, for example, the water body will be sucked into the intake pipe when the water body is sucked into the resonator, and the section will be larger when the water body is sucked into the resonator, so that the vacuum suction force will not be sucked into the water.
However, when the car air intake is submerged in water, the role of the resonator will lose the ability to mitigate the vacuum effect.
The resonator is also called the resonator, at the front end of the intake straw, generally in the front, the front down position. The main function is to reduce intake noise. In addition, increasing the space in the middle of the tube can act as a buffer and stability effect on the intake air
