Abstract
An engine assembly may include an engine block defining a cylinder bore, a piston disposed within the cylinder bore, and a spark ignited direct injection fuel system. The piston may be disposed within the cylinder bore and may be reciprocally displaceable from a first position to a second position during an intake stroke. The cylinder bore and the piston may partially define a combustion chamber. The spark ignited direct injection fuel system may include a fuel injector that provides a fuel flow to the combustion chamber during the intake stroke. The fuel flow may be directed toward an upper surface of the piston when the piston is in the first and the second positions.
