Abstract

An intake manifold is provided that controls swirl on entry to a combustion chamber. Each intake manifold includes a fin or rib portion positioned to reduce or eliminate swirl induced by the configuration of the intake manifold, particularly when used in a large engine having a left bank and a right bank of combustion chambers. By controlling swirl induced by the intake manifold, charge motion consistency is improved between engine cylinders and between the left bank and the right bank, thereby improving the consistency of combustion and power output, improving efficiency and reducing emissions (e.g., decreased particulate emissions (also described as smoke), hydrocarbon emissions, and NOx emissions), and further including an improved knock margin, improved fuel economy, wider rich and lean limits, etc.
