The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). The study used two fuels—an E10 and E15.

It has been a challenge to determine how much each polluter contributes to the emission output. However, the amount of pollutant emissions that vehicles emit on a daily basis depends on numerous factors, for example on individual driving behavior. —Karl et al.

NO x is a precursor for both ground level ozone and secondary PM 2.5 A wide variety of technology options can be deployed on heavy-duty engines and vehicles to reduce engine-out NO x while improving fuel economy to reduce the total cost of ownership of trucks. —MECA Executive Director, Rasto Brezny.

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels.

The chemistry of a fuel impacts the emissions from an engine, with the most obvious example being unburned or partially burned fuel which is a major component of engine exhaust. Engine-out exhaust contains typically 1?3% 3% unburned or partially burned organic fuel components. Emissions Engines Ethanol Fuels'

Gasoline direct-injection (GDI) engines have higher fuel economy compared to the more widely used port fuel injection (PFI) engines. We estimate ozone and SOA formation potential. Therefore, the secondary organic aerosol and ozone formation potential of the exhaust does not depend on engine technology.
