ABSTRACT:
An engine is provided which includes various precise configuration parameters, including dimensions, shape and/or relative positioning of the combustion chamber features, resulting in a combustion process minimizing NOx emissions and particulates. The combustion chamber includes one or more of the following: a spray angle relative to an inner bowl floor angle; a vertical distance from the tip of the piston bowl to the injection orifices; a number of injection orifices; a swirl ratio; a vertical distance from the injection orifices to an inner face of the cylinder head; a radius of curvature of an outer bowl section; chamfer with dimensional parameters; and a transition radius.
