Beschreibung
Zusammenfassung:	An engine (10) 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 (14) includes a spray angle relative to an inner bowl floor angle (Ù) that maximizes the amount of fuel in contact with the inner bowl, in combination with one or more of the following: vertical distance from the tip of the piston bowl (56) to the injection orifices; number of injection orifices (40); swirl ratio; vertical distance from the injection orifices to an inner face of the cylinder head (20); distance from the piston top surface to the cylinder head; radius of curvature of an outer bowl section; radius of curvature at an edge of the piston bowl; ratio of the piston bowl diameter to the cylinder diameter; and the cylinder diameter.
