ABSTRACT:
A spark ignited, reciprocating internal combustion engine, including a piston housed within a cylinder closed by a cylinder head has a fuel system for injecting fuel directly into the engine cylinder so as to achieve a homogeneous mixture with the fuel injection system injecting a first fraction of fuel during a first injection event and a second fraction of fuel during a second injection event.
