SNOWMOBILE ENGINE EMISSIONS AND THEIR IMPACT

This paper describes a research program on exhaust emissions from snowmobile engines, including both emissions characterization and estimation of national emissions impact. Tests were conducted on three popular 2-stroke twins and on one rotary (Wankel) engine. Emissions that were measured included total hydrocarbons, (paraffinic) hydrocarbons by NDIR, CO CO2, No (by two methods), NOX, 02, aldehydes, light hydrocarbons, particulate, and smoke. Emissions of SOX were estimated on the basis of fuel consumed, and evaporative hydrocarbons were projected to be neglibible for actual snowmobile operation. Impact of snowmobile emissions on a national scale was computed to be minimal.
