This component is a system responsible for directing air into the combustion chamber of an internal combustion engine equipped with a specific cylinder head design. An example of its application is found in certain diesel engines where each cylinder has two intake valves and one exhaust valve. This arrangement influences airflow characteristics and combustion efficiency.
Its importance lies in its contribution to engine performance, particularly in terms of power delivery and fuel economy. Optimizing the system improves volumetric efficiency, which allows the engine to draw in more air for combustion. Historically, the design marked a step towards increased power and efficiency compared to earlier two-valve-per-cylinder designs, offering improved breathing capability at higher engine speeds.
