Abstract: A combustion chamber of diesel engine. The diesel engine includes a cylinder head, a cylinder sleeve, and a piston. The cylinder head, the cylinder sleeve, and the piston form the combustion chamber. The combustion chamber includes a headspace; a central part; and a collision belt. The collision belt includes a collision surface, an upper guide surface, and a lower guide surface. The collision belt is configured to connect the headspace and the central part. The collision surface is an inclined surface, a convex surface, or a concave surface. The first tapered surface includes a second inclined surface, a second curved surface, and a third inclined surface; the second tapered surface includes a fourth inclined surface, a third curved surface, and a second concave surface; the first curved surface includes a second convex surface and a third concave surface.

Abstract: A diesel combustion system including an injector and a combustion chamber. The combustion chamber is formed by a cylinder head, a cylinder liner, and a piston. The combustion chamber includes an upper layer and a lower layer. The diameter D1 of the upper layer is larger than the diameter D2 of the lower layer. A junction of the upper layer and the lower layer is provided with an impinging block for rebounding the diesel fuel spray. The impinging block includes an impinging surface, an upper guide surface, and a lower guide surface. When in use, part of the diesel fuel spray is rebounded by the impinging surface, and part of the diesel fuel spray is diffused along the upper guide surface and the lower guide surface of the impinging block to achieve double-layered split flow of the diesel fuel.

Abstract: A diesel combustion system including a piston, an annular impinging block, and a combustion chamber. The combustion chamber is divided by the annular impinging block into an upper chamber and a lower chamber. The annular impinging block includes a lower guide surface that is adjacent to the lower chamber and that extends from a trough line connected to the piston to a crest line. The ratios among the inner diameter of the top of the piston, the outer diameter of the top of the piston, the diameter of the trough line, and the diameter of the crest line define the shape of the combustion chamber which leads to increased rate of combustion, reduced soot emission, and increased fuel efficiency.
