NREL study probes emissions impact of butanol-gasoline blends in light-duty vehicles

Green Car Congress

Results of a study led by a team from the National Renewable Energy Laboratory on the impact of butanol-gasoline blends on light-duty vehicle emissions suggest that widespread deployment of n-butanol or i-butanol in the gasoline pool could result in changes to the estimated emissions of alcohols and carbonyls in the emissions inventory.

International automotive researchers emphasize the importance of continued development of the internal combustion engine

Green Car Congress

A transition from the gasoline or diesel ICE to a full gasoline/diesel hybrid can significantly reduce emissions. This could be paired with combustion technologies with highly diluted combustion (stoichiometric with exhaust gas recirculation (EGR) as well as lean burn with excess-air ratios above 2). Gas exchange.

32.5M hours of supercomputer time to aid GM, Ford engine projects with Oak Ridge Lab

Green Car Congress

The project led by Tang-Wei Kuo from General Motors is focused on optimizing multi-hole injectors for spark-ignited direct-injection (SIDI) gasoline engines. Recently, the most popular SIDI gasoline injectors have been multi-hole type. The current design optimization process is very time- and labor-intensive. Click to enlarge.

Growth Energy and Ethanol Producers Request Waiver Allowing E15 from EPA

Green Car Congress

No statistically significant change was detected. GM has produced more than 5 million flex-fuel vehicles capable of handling ethanol blends of up to 85% (E85), but still has remaining questions over the impact of mid-range blends on durability and catalyst lifetime in non-E85 gasoline vehicles, for example. Earlier post.).
