The role of car vents

Generally speaking, as the exhaust device of a car, the function of the exhaust hole is to allow the engine to discharge exhaust gas in time during operation, and to achieve the effect of purification and noise reduction. Originally, some large-displacement cars are indeed different from ordinary cars. The design of car vents is different. Adding a few car vents makes the visual impact stronger, making people feel "so much." The exhaust holes are definitely used for exhaust, indicating that the displacement is large."

In fact, the reason why such a statement is one-sided is because it is partial and complete. Some large-displacement cars do need multiple exhaust holes to achieve the effect of eliminating exhaust gas. If there is only one car exhaust hole, then the diameter must be large to ensure normal exhaust, but the more exhaust Larger, the noise will be louder, so in order to look good and reduce noise, many large displacement cars will involve several car exhaust holes.
