UNL study finds non-flex fuel vehicles can adapt to E30 gasoline without performance compromise; fuel efficiency comparable to E15

Green Car Congress

A team at the University of Nebraska-Lincoln has investigated the long-term adaptability and economic feasibility of non-flex-fuel vehicles—vehicles designed to use fuel blends containing 85% ethanol (E85) or less—to consume a 30% ethanol (E30) fuel blend.

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.

List of The Best 10 Alternative Fuels for Cars that Could Replace Gasoline

Get Electric Vehicle

Which are the alternative fuels for cars that could replace gasoline in vehicle? Let’s see a quick statistic. Methanol can be used in internal combustion engines either directly or as a blend with gasoline. FFVs are designed to run on blends of methanol and gasoline in different ratios. It is not a low value.

Caltech, JPL designed megasupramolecule fuel additive reduces intensity of post-impact fuel explosions

Green Car Congress

Researchers at Caltech and JPL used statistical mechanics to design a polymeric fuel additive that can self-assemble into “megasupramolecules” (≥5000 kg/mol) at low concentration (≤0.3 weight percent) and thus can reduce the intensity of post-impact fuel explosions that occur during accidents and terrorist acts.

Study: consumer products overtake transportation as largest source of VOCs air pollution in cities

Green Car Congress

The green symbol and dashed arrow illustrate the large reductions in tailpipe VOC emission factors as precatalyst on-road gasoline vehicles were replaced by present-day vehicle fleets. The new study, with its detailed assessment of up-to-date chemical use statistics and previously unavailable atmospheric data, puts the split closer to 50-50.

Review of studies finds it difficult to reach summary conclusions on ethanol’s emissions effects

Green Car Congress

However, the first major study of new gasoline direct injection (GDI) engines did not find that NO x had a statistical increase. Suggestions for potential study designs are incorporated in the report. They should also consider refinery economics and not blend just high-value streams.
