Abstract

The invention relates to an engine having the fuel injection induced combustion chamber mixing. 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 an intake port in communication with the cylinder bore and adapted to mitigate intake air swirl within the cylinder bore. The piston may be disposed within the cylinder bore for a reciprocal stroke between a top dead center position and a bottom dead center position. The piston may define an annular recess portion in an axial end surface thereof. 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 spray may define an annular plume intersecting the annular recess portion in the piston when the piston is in an injection position within twenty percent of the reciprocal stroke from the top dead center position.

Description

technical field [0001] The present invention relates to an internal combustion engine including a direct injection fuel system. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] The engine assembly may include a direct engine fuel system that supplies a fuel supply directly to a combustion chamber of the engine. Typically, direct injection fuel systems may include a centrally located fuel injector. During injection, the fuel injector may provide multiple radial fuel injection streams directly to the combustion chamber wall. The orientation of the fuel injectors and the resulting injection of fuel causes the fuel to impinge on the walls of the combustion chamber and thus restrict mixing within the combustion chamber. Contents of the invention [0004] Engine components may include engine structures, pistons, and a direct injection fuel system. The engine structure may...
