Abstract
Embodiments of two-cycle crankcase compression direct injected internal combustion engines that permit good firing and effective stratification, particularly at low speed, low load conditions. The engine defines a combustion chamber having a recess with a projection extending into the center of the recess and against which fuel is injected by a fuel injector as the piston approaches top dead center at idle. The spark plug firing is initiated prior to completion of the fuel injection. A specific configuration and orientation for the fuel injector nozzle in relation to the projection size and cylinder bore size is established so as to insure that at least 50% of the fuel injected at low and idle speed conditions will impinge upon the projection.
