Abstract

Abstract A motorcycle with a two-cylinder V-type engine employs an exhaust manifold comprising exhaust pipes connected to the engine cylinders and extending laterally inward to a central tubular support in front of the engine. A turbocharger device mounted on said support includes a turbine driven by exhaust gases from the exhaust manifold and an air compressor coupled to the turbine to deliver air under pressure to the intake system of the engine.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 106 words
A turbocharger system for a motorcycle having a multicylinder V-engine with a crankshaft, the engine being supported on a body frame between front and rear wheels with the centerline of the engine extending fore-and-aft of the motorcycle, the turbocharge system comprising an exhaust manifold including a hollow support rigidly fixed to the engine and exhaust pipes connected to the engine cylinders and extending toward the axis of the crankshaft and converging to said hollow support; and a turbocharger mounted to and positioned atop said hollow support adjacent one end of the V of the multicylinder V-engine and including an engine intake pipe extending toward the engine.
Claim 2
Dependent Claim 106 words
A turbocharger system for a motorcycle having a multicylinder V-engine with a crankshaft, the engine being supported on a body frame between front and rear wheels with the centerline of the engine extending fore-and-aft of the motorcycle, the turbocharge system comprising an exhaust manifold including a hollow support rigidly fixed to the engine and exhaust pipes connected to the engine cylinders and extending toward the axis of the crankshaft and converging to said hollow support; and a turbocharger mounted to and positioned atop said hollow support adjacent one end of the V of the multicylinder V-engine and including an engine intake pipe extending toward the engine.
Claim 3
Dependent Claim 34 words
