| description | A balancer mechanism is disclosed for a straight engine including an odd number of three or more cylinders, a crankshaft having a crank journal, crank arms spaced apart at a predetermined angular interval, a reciprocating portion and a rotating portion generating an inertia couple in the crankshaft, and a crank weight producing a combined inertia couple in the crankshaft by reducing some of the inertia couple. The axes of the cylinders are arranged offset with respect to the axis of the crank journal. The balancer mechanism includes a balance shaft and a balance weight arranged in the balance shaft in order to cancel the combined inertia couple. The phase of the rotation angle of the balance shaft with respect to the rotation angle of the crank journal is retarded by a predetermined angle with respect to such a reference phase that can cancel the combined inertia force in a case in which the axes of the cylinders cross the axis of the crank journal. |
