What will happen if the car intake pipe leaks

The different shapes, lengths, and cross-sectional areas of the intake pipes represent the design requirements of the engine. From a shape perspective, the intake pipe can include vertical intake and swirl intake. Due to the low intake resistance, a vertical intake duct is conducive to resonance at high speeds, improving intake efficiency and facilitating the arrangement of fuel injectors. Most engines exhibiting symptoms at high speeds meet the requirements of objective conditions. The vortex type intake duct helps to induce vortices during intake, improve the mixing degree of air and gasoline, and enhance the combustion efficiency in the cylinder at low speeds. Most engines that meet objective conditions exhibit symptoms during strong low-speed revs.

For example, the BMW brand's M5 is equipped with a V10 engine, which does not use many complex technologies to improve the engine's response speed, high-power output at high speeds, etc. Mitsubishi and Honda from Japan have achieved high-performance interpretation in the most direct and pure way possible. The ten intake pipes of this V10 engine mostly adopt a very short vertical design, and each intake pipe is basically equipped with a throttle valve. These are the most prominent design features that emphasize high rotation and responsiveness. However, the most noticeable rotation of the intake port is still in diesel engines. Most diesel engines have relatively low engine speeds, with a focus on the power performance symptoms at low speeds. Therefore, diesel engines without exception all use swirl intake ports. Some diesel vehicles intentionally increase the swirl at the end of the intake duct to create the maximum intake swirl and improve the air-fuel mixture. But as the speed increases, the speed and frequency of intake become faster, and the vortex generated by the inertia of the airflow becomes the main culprit for reducing intake efficiency, making it difficult for the oil and gas mixture to be drawn into the cylinder faster.

I think this is easy to understand. The air resistance caused by a spiral pipeline is definitely much greater than that of a straight pipeline. So at this time, vertical intake is more suitable for the engine's operating conditions.
