Swirl flaps意思

Swirl flaps are components found in the intake manifold of some diesel engines. They are designed to improve engine performance, especially in terms of fuel efficiency and emissions.

The swirl flaps are small doors or flaps that can be opened or closed to control the airflow inside the intake manifold. When the engine is running at low speeds, the swirl flaps are closed, which helps to create a swirling motion of the air as it enters the cylinder. This swirling motion improves the mixing of air and fuel, which can improve combustion efficiency and reduce emissions.

At higher engine speeds, the swirl flaps may be opened to allow for a more direct flow of air into the cylinder, which can improve engine performance and power.

Swirl flaps are often used in conjunction with other engine management systems, such as turbochargers and direct injection, to optimize engine performance across a wide range of operating conditions.
