| 摘要： | The University of Idaho's entry into the 2005 SAE Clean Snowmobile Challenge (CSC) was a second-generation gasoline direct-injection (DI), two-stroke powered snowmobile. A battery-less direct-injection system was used to decrease exhaust emissions and improve fuel economy without reducing the power output of the engine. A spiral exhaust silencer reduced exhaust noise. Under-hood noise was targeted by using sound absorbing materials and a sealed hood. Chassis noise was addressed by using a spray-on rubberized material that absorbs vibrations transferred through the chassis. Power transfer and space issues were addressed with the addition of a direct-drive system that eliminated the jackshaft. The snowmobile entered into the 2005 SAE CSC competition was lightweight, fun-to-ride, powerful, and had reduced exhaust emissions. |
