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.

Claim (Index 1):
A system for combusting diesel fuel, the system comprising:\n an injector; a combustion chamber, said combustion chamber comprising a first chamber and a second chamber; a cylinder head; a cylinder liner; a piston, the piston comprising a piston top; and an annular impinging block, the annular impinging block comprising an impinging surface, a first guide surface, and a second guide surface; wherein:\n said cylinder head is disposed on said cylinder liner; \n said injector extends through said cylinder head; \n said piston is inserted in said cylinder liner and movable with respect to said cylinder liner; \n said annular impinging block protrudes from said piston toward said injector; \n said combustion chamber is confined by said cylinder head, said cylinder liner, said piston, and said impinging block; \n said combustion chamber is subdivided by said impinging block into said first chamber and said second chamber; \n said first chamber is disposed adjacent to said cylinder head; \n said first guide surface is disposed adjacent to said first chamber; \n said second guide surface is disposed adjacent to said second chamber; \n said impinging surface is disposed between said first guide surface and said second guide surface; \n said injector is adapted to inject the diesel fuel toward said impinging surface; \n said impinging surface is a convex surface; \n said second guide surface and said piston intersect at a trough line; \n said second guide surface and said impinging surface intersect at a crest line; \n said second guide surface extends from said trough line to said crest line; \n the ratio of an inner diameter of said piston top to an outer diameter of said piston top is larger than 0.75; \n the ratio of a diameter of said crest line to said outer diameter of said piston top is smaller than 0.6; \n the ratio of a diameter of said trough line to said inner diameter of said piston top is smaller than 1; and \n the ratio of said diameter of said trough line to said diameter of said crest line is larger than 1.06.
