Effect of Biomass-based Lubricants on the Performance and Emissions of a Two-Stroke Snowmobile Engine

The emissions benefits and any negative long-term consequences encountered when using biomass-based lubricants are discussed. For example, soy-based two-stroke oils are commercially available for use in existing engines. These oils should produce comparable emissions to their petroleum and synthetic counterparts. They are also biodegradable when incidentally released to the air, land, or water. These products conform to all current legislation regarding air, land, and water pollution. Most snowmobile enthusiasts either are unaware of these products, or refrain from their use due to superstition or rumor. A production two-stroke engine, designed for snowmobiles, has been tested when using both standard, petroleum based lubricants, and when using soybean derived lubricants. This paper studies not only the production of emissions resulting from the use of these lubricants, but also looks at any negative consequences such as possible corrosion due to the use and storage of these lubricants.
