CMU/Yale study suggests BEVS could be majority or near-majority of cars and SUVs by 2030 given technology trends

Green Car Congress

A suggestive market-wide simulation extrapolation indicates that if every gasoline vehicle had a BEV option in 2030, the majority of new car and near-majority of new sport-utility vehicle choice shares could be electric in that year due to projected technology improvements alone. —Forsythe et al.

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.

New method for knock control could improve fuel efficiency, emissions and torque

Green Car Congress

Researchers at Villanova University are developing a new method for optimizing the knock control threshold that significantly improves the performance of a standard knock controller in a spark ignition gasoline engine. The most recent paper on their work appears in the International Journal of Engine Research. —Jones et al.

UC Riverside researchers find mixed emissions impact from use of higher ethanol and butanol fuels in FFVs

Green Car Congress

Emissions of nonmethane hydrocarbons (NMHC) and carbon monoxide (CO) showed some statistically significant reductions with higher alcohol fuels, while total hydrocarbons (THC) and nitrogen oxides (NO x ) did not show strong fuel effects.

Bosch overview of global diesel markets; optimistic about US, China

Green Car Congress

This statistic increases to two-thirds of all new registrations if the data are restricted to passenger cars, according to Bosch. The resulting increase in internal trade and transportation of merchandise will also lead to a significantly more prominent role for diesel, Bosch says. Brazil: no diesel in passenger cars.

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

Green Car Congress

The two projects are part of a larger multi-year DOE-funded project to develop and to apply innovative simulation strategies and tools to maximize benefits of predictive information from high performance computing (HPC) for internal combustion engines. Recently, the most popular SIDI gasoline injectors have been multi-hole type.
