摘要： A plurality of convex portions are radially fanned and spaced apart from each other by a constant angle in a planar view on a tapered surface of a land portion formed on a bottom surface of a cavity formed in a top portion of a piston. Each convex portion is positioned such that the extending direction of the convex portion aligns with an axis X of a corresponding fuel spray. Thereby, each fuel spray moves forward through a space (convex portion space) between the corresponding convex portion and an inner wall of a cylinder head portion along the extending direction of the corresponding convex portion. When a fuel injection is performed during the latter half of a compression stroke, a pressure in a convex portion space is increased, compared with a pressure in a space of the other portion by the decrease of a ratio of the volume of the convex portion space relative to the volume of the space of the other portion by the proceeding of the compression by the piston. Each fuel spray is circumferentially expanded by the pressure difference.

摘要： An internal combustion engine includes an engine assembly that defines a bore, and a piston disposed and moveable within the bore. The piston and the engine assembly cooperate to define a combustion chamber therebetween. A direct injection fuel system directs a fuel spray into the combustion chamber along a linear path. The combustion chamber includes a contoured surface having a plurality of annular recesses. The contoured surface divides and re-directs the fuel spray from the linear path into each of the annular recesses to form a plurality of independent rotating vortices.

摘要： A piston and internal combustion engine therewith constructed in accordance with the present invention has a piston body with an upper crown having a substantially cylindrical outer surface depending from a top surface along a central axis. At least one annular ring groove extends radially into the outer surface to provide a top land extending from the ring groove to the top surface. A plurality of waves are formed circumferentially about the top land. Each of the waves has a valley extending radially into the outer surface of the top land and extending from the top surface to the ring groove. The waves traverse from the top surface to the ring groove and are configured in substantially non-overlapping relation with one another and in a predetermined orientation relative to at least one of a fuel spray stream, a pin bore axis or a thrust axis of the piston.
