ABSTRACT:
A two-plane type crankshaft is provided. The weight of crank webs for the respective cylinders is divided between left and right half webs and balance ratios kLand kRof the half webs for the respective cylinders are set so as to be (kL−0.25)·(0.25−kR)≅DR/DLto form a track of a vector of a primary inertial couple into a substantial circle. A primary balancer offsets the primary inertia couple.
