An engine assembly may include an engine structure, a piston, and a direct injection fuel system. The engine structure may define a cylinder bore and the piston may be disposed within the cylinder bore for reciprocal displacement between a top dead center position and a bottom dead center position. The direct injection fuel system may include a fuel injector that provides a fuel spray to a combustion chamber defined by the piston and the cylinder bore. The fuel flow may extend generally tangential to a circumference of the combustion chamber and may define a centerline extending in a direction radially across the combustion chamber. |
