CARB releases results of multi-year E15 study; multiple air quality benefits with slight reduction in fuel economy

Green Car Congress

JULY 18, 2022

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). California currently limits the ethanol content of gasoline to 10 percent.

Their paper is published in the ACS journal Energy & Fuels. Regulated emissions for all test fuels over the cold-start and hot-start LA92 cycles. A fuel economy penalty was also observed for lower energy content E30 and E78 blends compared to both E10 fuels. Data presented as mean ± standard deviation, N=3.

Using statistical methods, the scientists infer emissions from these data within a radius of about one kilometer of the measurement location. This has been hard to achieve for diesel powered cars, which nowadays mostly rely on selective catalytic reduction due to the high air to fuel ratio during combustion. —Thomas Karl.

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. Co-investigators are Ronald Grover (GM), Sreekanth Pannala (ORNL), and Wael Elwasif (ORNL).

Also, the list of standard test procedures addressed in SAE J1711 has been expanded to cover all five major test cycle procedures (UDDS, HFEDS, US06, SC03, and Cold FTP) now being used to evaluate vehicle fuel economy. Consumable fuels that are covered by J1711 are limited to petroleum-based liquid fuels (e.g.,

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines.

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. It is much more than that.
