The 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 correcting 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 tract 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°, 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.

La présente invention concerne un moteur à combustion interne, plus particulièrement un moteur à pistons alternatifs, vilebrequin et à coulisses circulaires, pour améliorer son équilibrage. Ce moteur comprend des corps de cylindres, des pistons, des coulisses circulaires et un vilebrequin. Chaque corps de cylindre comporte une cavité de glissement. Au moins trois coulisses mobiles d'équilibrage sont montées dans cette cavité et combinées pour former une pièce, la différence de phase entre deux coulisses voisines étant de 180 DEG . Chaque coulisse circulaire est montée dans les pistons ou dans des coulisses d'équilibrage mobiles correspondantes, de manière à pouvoir tourner, et toutes les coulisses circulaires sont montées sur un maneton de vilebrequin.
