Balancer structure for a V-type engine

A balancer structure for a V-type engine having a balancer shaft supported in parallel with a crankshaft of the V-type engine, the balancer shaft being positioned directly below the crankshaft and having a longitudinal axis positioned substantially in a center plane which divides cylinder banks of the V-type engine and which center plane passes through a longitudinal axis of the crankshaft, and the balancer shaft being disposed to rotate in an opposite direction from the crankshaft and at the same speed as the crankshaft.

A balancer structure for a V-type engine having a balancer shaft supported in parallel with a crankshaft of the V-type engine, the V-type engine including a plurality of crankshaft supporters disposed to support the crankshaft adjacent a lower part of a cylinder block of the V-type engine, a plurality of balancer shaft supporters positioned directly below the crankshaft and on a center plane which divides cylinder banks of the V-type engine and which center plane passes through a longitudinal axis of the crankshaft, the balancer shaft being supported and mounted to the balancer shaft supporters by respective balancer shaft caps, the balancer shaft supporters being respectively mounted on only some of the crankshaft supporters, and a plurality of balancing weights disposed on the balancer shaft below respective crankshaft supporters not having balancer shaft supporters mounted thereon.

A balancer structure for a V-type engine having a balancer shaft supported in parallel with a crankshaft of the V-type engine, wherein the crankshaft is supported by crankshaft supporters in a lower part of a cylinder block of the V-type engine, wherein a balancer shaft supporter is positioned directly below the crankshaft and on a center plane which divides cylinder banks of the V-type engine and which passes through a longitudinal axis of the crankshaft, the balancer shaft being supported and mounted to the balancer shaft supporter by a balancer shaft cap, and an oil pump which is offset sidewardly from and positioned generally below the crankshaft, the balancer shaft and a pump shaft of the oil pump being drivingly connected by a common chain.
