Thorough Analysis of a Two-Stroke Cycle Engine Versus a Four-Stroke Cycle Engine: Minnesota State University, Mankato's Entry for the SAE Clean Snowmobile Challenge 2002 2002-01-2764

This paper discusses the Minnesota State University, Mankato Automotive Engineering Technology program's entry to the 2002 Clean Snowmobile Challenge. Included in this report are the snowmobile model chosen for modification, engine choice, modifications applied, methods used, and modification results affecting performance, emission control, noise reduction, production cost, durability, fuel efficiency, safety, and rider comfort.
The MSU Mavericks devoted their main focus for the Clean Snowmobile Challenge 2002 to the comparison of a two-stroke cycle engine to a four-stroke cycle engine. A direct fuel-injected two-stroke cycle engine and a turbo-charged four-stroke cycle engine were selected and were subjected to extensive modifications and testing procedures. Each engine was tested for emissions, noise, and performance; these test results were used to determine the final entry design.
