摘要：
The present invention relates to a reciprocating piston type internal combustion engine, wherein the resultant of the vectors of inertia forces according to the rotation of the second and third balance weight means pass through the axis of the crankshaft and equal in value and opposite in the direction to the resultant vector of primary inertia forces of the piston-crank mechanism and the transmission means is provided to rotate the second and third balance weights.
