Abstract:
1. A snowmobile, comprising: a frame having a forward portion and a rear portion; a four-stroke engine mounted to said forward portion of said frame including at least one cylinder, each cylinder having a respective combustion chamber; a turbocharger associated with said engine; an endless belt mounted to said rear portion of said frame and operatively connected to said engine; an air intake system communicating with each said combustion chamber, and an exhaust outlet capable of communicating with each said combustion chamber; said air intake system including an air passage in fluid communication with the atmosphere, wherein said turbocharger is connected to said air passage such that air from said air passage may enter said turbocharger, the air passing through an airbox situated upstream of said turbocharger, said turbocharger communicating with said exhaust outlet and being constructed and arranged such that a flow of exhaust gases from said exhaust outlet through said turbocharger affects a pressurization of air therein; a heat exchanger formed of a heat conductive material connected to said turbocharger such that the pressurized air from said turbocharger may enter therein, said heat exchanger being constructed and arranged such that heat from the pressurized air is dissipated therefrom to the atmosphere via said heat conductive material, and at least a portion of the airbox being disposed forward of the heat exchanger.
