Automotive intake manifolds are an integral component of an internal combustion engine's air intake system. The primary function of the intake manifold is to evenly distribute the air/fuel mixture to each cylinder in the engine. The intake manifold is typically made of cast aluminum or molded plastic, and it is designed to withstand the high temperatures and pressures generated by the engine. The intake manifold is connected to the engine's throttle body, which regulates the amount of air that enters the engine. The air enters the manifold through the air filter and is then distributed to each cylinder through individual runners. The length and diameter of the runners are carefully designed to optimize the airflow to each cylinder, which helps to improve engine performance and efficiency. In addition to its primary function of distributing air to the engine, the intake manifold also plays a role in reducing engine noise and vibration. Some intake manifolds are designed with tuned resonators that help to reduce intake noise, while others are designed with a plenum chamber that helps to reduce vibration. Overall, the design of the intake manifold is critical to the performance and efficiency of an internal combustion engine. The length and diameter of the runners, the shape of the plenum chamber, and the use of resonators all play a role in optimizing the airflow to the engine and improving its overall performance.
