What are the possible technological solutions to reducing harmful emissions from snowmobile engines?
• Substituting four-stroke engines for two-stroke engines to improve fuel economy and reduce emissions. • Introducing fuel injection to replace carburetors in new two-stroke machines. • Improving fuel atomization in two-stroke engines for leaner burning mixtures. • Treating exhaust to reduce emissions from two-stroke engines. • Substituting rotary four-stroke engines for two-stroke engines to maintain power-to-weight ratios of the two-stroke engine. • Using ethanol blend gasoline and biodegradable lubricants.
