Abstract

A system and method for widening auto-ignition range of a lean burn internal combustion engine employs stratified charge of exhaust gas content and air content. A fuel injection system carries out a first injection of gasoline fuel for dispersion within the air content, and a second injection of gasoline fuel for dispersion within the exhaust gas content. This intelligent injection of gasoline fuel accomplishes auto-ignition of gasoline fuel within the exhaust gas content over extended range of engine speed and load.
