Small-displacement two-stroke H2 engine could address performance and emissions cost-effectively for recreational market; potential for Asian motor vehicle fleet
Green Car Congress
SEPTEMBER 26, 2012
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
DOE to award up to $184M for advanced vehicle research and development in 8 areas of interest
Green Car Congress
DECEMBER 16, 2010
This subtopic seeks research and development projects on novel lubricant formulations expected to improve the efficiency of advanced combustion regime engines by at least 10% (improvement based on comparison to similarly configured 2002 or later commercially available combustion engine). AOI 2: Lightweighting Materials.
NREL review of E15 effects on MY2001 and later cars finds no meaningful differences with E10
Green Car Congress
OCTOBER 13, 2013
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).
Pinnacle 4-stroke opposed-piston SI engine shows fuel economy improvements of between 30-60% at light loads, 12-30% at medium loads over conventional

Comparison of ISFC (@42.9 Pinnacle Engines’ 110cc production-intent prototype packaged for a motorcycle application. The test engine for the paper was a 250cc single-cylinder unit with dual-camshaft-actuated reciprocating sleeve valves for induction and exhaust. Source: Pinnacle. Click to enlarge. Click to enlarge.
VW of America introducing the Golf SportWagen; increased cargo volume and fuel efficiency; up to 43 mpg highway with diesel

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.
