DOE to award up to $184M for advanced vehicle research and development in 8 areas of interest

Green Car Congress

The engines shall have extremely low engine-out nitrogen oxides (NO x ) and particulate matter (PM) as a target; and shall have efficiency similar to state-of-the-art direct injection diesel engines (i.e., approximately 45% peak thermal efficiency for light duty and greater-than 50% peak thermal efficiency for heavy duty).

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

Green Car Congress

The results represent a light-load indicated efficiency improvement of 15-30% (up to 40.9%). With the extended lean operation of the sleeve-valve engine, NO x emissions remain low for light to medium loads and rise back to typical levels during the brief enrichment periods required to maintain competitive BMEP levels at higher loads.
