This invention relates to a biased connecting rod having a crank pin inserting hole in the larger end portion of the connecting rod biased from the piston movement direction through a piston pin-inserting hole in the smaller end portion. In general, a connecting rod (21) of a conventional engine is run straight along the piston (12) movement direction passed through both the center of the crank pin inserting hole (15) in the larger end portion (22) and the center of the piston pin inserting hole (16) in the smaller end portion (23) at the very moment that its piston (12) is positioned at the top dead center. Thus, if the crank pin has a large diameter, an actual work is reduced in proportion with the diameter. In order to overcome the defects, the biased crank pin according to the present invention is so constructed that the prevailing combustion pressure FCON changes its course at the piston pin inserting hole (16) in the smaller end portion (43) is toward a peripheral portion of the crank pin biased from its center. |
