Comparison of brake thermal efficiency and specific fuel consumption at rated power (ICOMIA Mode 5), hydrogen vs. gasoline engines. Such an engine could provide a cost-effective solution for small recreational vehicle- and motorcycle applications. Everything else—pistons, porting and crankcase, bearings, exhaust, etc.—were

emissions are small two-stroke engines that are used in outdoor power equipment such as leaf blowers, chain saws, and string trimmers, as well as larger two-stroke engines used in recreational vehicles such as all-terrain vehicles (ATVs), motorcycles, snowmobiles, and marine outboard motors. Significant sources of PM2.5

The study does not address engines that EPA has not approved for use with E15, such as pre-2001 cars, marine, snowmobile, motorcycle, and small non-road engines. The data presented in these studies did not show any evidence of deterioration in engine durability or maintenance issues for E15 (or E20) in comparison to E0 and E10 (when tested).

Quick comparison of fuel economy and cargo. The engine is also extremely compact, illustrated by the way in which the exhaust manifold has been integrated directly into the cylinder head. The sensor acquires both the position of stationary cars and motorcycles as well as those moving in the same direction as the Jetta.
