Description
Summary:The 2006 MSU-X Clean Snowmobile Challenge team has made significant modifications to the two-stroke cycle engine in a 2005 Arctic Cat F5 APV. The goals of the team were to improve emissions, noise, and fuel economy while maintaining stock performance and handling characteristics. To obtain these results, a semi-direct fuel injection system was developed and the power valves were removed. An engine management system was used in place of stock systems to control fuel and ignition. A two-way catalytic converter and an air pump to reduce hydrocarbon and carbon monoxide emissions was incorporated into the exhaust system. Sound levels were lowered with the use of a custom extended exhaust system and sound dampening materials underneath the hood. These modifications produced a light weight, performance oriented snowmobile that also has reduced exhaust emissions.
