PCT No. PCT/CN96/00042 Sec. 371 Date Jan. 15, 1998 Sec. 102(e) Date Jan. 15, 1998 PCT Filed Jun. 13, 1996 PCT Pub. No. WO96/41936 PCT Pub. Date Dec. 27, 1996The present invention relates to internal combustion engines, particularly to a reciprocating piston type internal combustion engine with a crank and multiple circular slide blocks, formed by substituting connecting rods with circular slide blocks. The engine comprises a crank-and-circular slide block mechanism including a cylinder body, pistons, circular slide blocks, a crankshaft and the like. In the cylinder body, there is a sliding track in which there is a dynamic balance sliding piece. There are at least three circular slide blocks connected into an integral, with the phase difference of the adjacent circular slide blocks being 180 DEG , and the circular slide blocks being rotably received in the pistons or the dynamic balance sliding piece and all being sleeved on the same crank pin. The engine of the present invention has excellent dynamic balanceability and compact configuration; and compared with existing engines of the same type, its size and weight are 30-50% and the man-hour for manufacture is 50-60%, and 70% of the parts are commonly used ones, it is reliable in operation, has long service life and low energy-consumption.
