Abstract
A housing partially defines a combustion chamber. A movable piston partially defines the combustion chamber. An air and fuel mixture is generated in the combustion chamber. The air and fuel mixture is ignited in the combustion chamber. An obstacle member is fixedly disposed in the combustion chamber. The obstacle member serves to generate turbulence in an unburned portion of the air and fuel mixture after the air and fuel mixture is ignited. Fuel may be injected into at least two points in the combustion chamber.
