摘要： A compression ignition internal combustion engine includes a nozzle that is provided in a cylinder head and that injects fuel directly into a combustion chamber, and a piston in which a cavity is provided in a top surface thereof. The cavity includes a conical bottom surface, a curved surface that continues from the bottom surface toward a radial outside and curves toward the cylinder head side, and an inside surface that extends from the curved surface toward the cylinder head side. The inside surface includes a first inside surface, and a second inside surface that is separated from the first inside surface in a circumferential direction, and is closer to the nozzle than the first inside surface is. The nozzle injects a fuel spray toward each of the first and second inside surfaces. The curved surface includes first and second curved surfaces that are continuous with the first and second inside surfaces, respectively. A curvature radius of the first curved surface is smaller than a curvature radius of the second curved surface.

摘要： A piston for an internal combustion engine including a cooling gallery and a complex combustion surface Is provided. The piston includes an upper crown member joined to a lower member, for example by hybrid induction welding. A complex combustion bowl is formed in the upper crown member by forging. The combustion bowl includes at least one protrusion, and typically a plurality of protrusions spaced from one another. After the forging step and before the joining step, portions of an undercrown surface located opposite the spaces between the protrusions are machined, and portions located directly opposite the protrusions are left as-forged. The crown member is joined to the lower member, for example by hybrid Induction welding.
