Abstract
A system and method for controlling combustion in a direct injection spark ignition internal combustion engine inject fuel directly into a combustion chamber through an injector having an ignition jet or group of jets positioned primarily to support stratified charge formation and a mixing jet or group of jets positioned primarily to support homogeneous charge formation. The ignition jet(s) and mixing jet(s) produce discernibly different yet well connected fuel clouds within the cylinder to provide stable combustion and reduce cylinder wall wetting by appropriate selection of the axial/longitudinal angles and radial/circumferential angles of the ignition and mixing jets.
