Engine with balancers for a vehicle

摘要

A starter motor and balancers are disposed in an engine so as not to interfere with each other by effectively utilizing spaces in an engine. Cylinders are set so as to be tilted forward on casings (4,5) supporting a crankshaft (3) in a transverse position, a rear balancer (Br) and a starter motor (78) are disposed in a space behind the cylinders, and a front balancer (Bf) is disposed on an opposite side of the rear balancer (Br) with respect to the crankshaft (3). The rear balancer (Br) and the front balancer (Bf) are disposed on the right side of a plane (P ) including the center of gravity (CG) of the engine (E) and perpendicular to the crankshaft (3), and the starter motor (78) is disposed on the left side of the plane (P 1 ) . Weight portions (58a, 67a) included in the rear balancer (Br) and the front balancer (Bf) are disposed close to the plane (P ) to prevent coupling vibrations.
