Abstract
An exhaust system for V-twin engines having a pair of engine cylinders connected to a crankcase to define a V-space therebetween. Each of the cylinders includes an exhaust port which faces outwardly of the V-space, and a pair of mufflers are attached directly to the exhaust ports of the respective engine cylinders. In this manner, the exhaust ports and mufflers are disposed outside of the V-space to promote the ready dissipation of the heat associated with the exhaust gases to the atmosphere. A common exhaust conduit is connected to both of the mufflers, and carries exhaust gases from the mufflers to a common exhaust outlet.
Claims20
An internal combustion engine, comprising:
- a crankcase;
- a pair of cylinders connected to said crankcase and defining a V-space therebetween, each cylinder including an exhaust port facing outwardly of said V-space;
- a pair of separate mufflers respectively attached to said exhaust ports;
- and
- an exhaust conduit connected to both of said mufflers, said exhaust conduit including at least one exhaust outlet.
An internal combustion engine, comprising:
- a crankcase;
- a pair of cylinders connected to said crankcase and disposed in an angular relationship to one another, each said cylinder including an exhaust port;
- a pair of separate mufflers respectively attached directly to said exhaust ports;
- and
- a common exhaust conduit connected between said mufflers, said exhaust conduit including an exhaust outlet.
In combination:
- an internal combustion engine, comprising:
- a crankcase;
- and
- two cylinders connected to said crankcase and disposed in an angular relationship to one another, each cylinder including an exhaust port;
- and
- an exhaust system, comprising:
- two separate mufflers respectively attached to said exhaust ports;
- and
- a common exhaust conduit having two end portions respectively connected to said mufflers, said exhaust conduit including an exhaust outlet.
