ABSTRACT:
A gasoline engine fuel injection system is described wherein, during each air intake stroke, the ratio of instantaneous fuel flow rate to instantaneous air flow rate can be essentially constant. By use of this injector system optimum low emission air to fuel ratio can be created within all portions of the intake mixture. Stratified intake mixtures can be created by use of a modified form of the injector system. Such stratified mixtures can be utilized, when needed, to suppress violent compression ignition and knock.
