This report includes test data, documentation, and discussion on detailed exhaust emission characterization of four snowmobile engines (three two-stroke cycle and one rotary combustion cycle). It also covers the estimation of emission factors and national air quality impact. Broad regional and seasonal estimates of the distribution of these emissions are also made. The exhaust products measured include HC, CO, CO2, NO, O2, light hydrocarbons, aldehydes, particulate, and smoke; SOx emissions were calculated rather than measured. The engines were operated with steady-state 'mapping' procdures using 20F intake air.
