Stratified charge injection for gas-fueled rotary engines
This patent describes a stratified charge injection for gas-fueled rotary engines having an air intake stroke, a compression stroke, a power stroke, and an exhaust stroke. It comprises a rotor housing, the housing including an air intake port and an exhaust port, and an outer perimeter, a rotor rotatable in the housing, a gaseous fuel injector supplying all of the fuel is connected to the housing between 270{degrees} and 360{degrees} of the rotor rotation after compression top dead center and downstream of the air intake port, the injector providing gaseous fuel at a pressure less than peak compression pressure, the injector located in the middle of the width of the outer perimeter of the housing, spark ignition means in the housing downstream of the injector, and means connected to the fuel injector responsive to the compression pressure for controlling the rate and duration of fuel injection.
