Abstract

An inlet air passage (14) introduces air into a cylinder bore (12) of a diesel engine (10) in a direction along a flow path substantially tangent to the cylinder bore to provide a swirling of the air within the bore. A second inlet air passage (14) introduces air into the same cylinder bore in a direction along a flow path toward the centerline of the cylinder bore axis which minimizes swirl within the cylinder bore. The non-swirling air flow path is utilized during start up and cold idle and the swirling air flow path is individually used when the engine operates through its intermediate speed range with both air flow paths being simultaneously directed into the cylinder bore during high speed operation of the engine for optimum volumetric efficiency.
