Study finds PM from biodiesel blends may be 50-80% less toxic per unit PM mass than from petroleum diesel

Green Car Congress

The researchers analyzed samples of PM obtained from light-duty diesel engine transient cycle emission tests with two biodiesel feedstocks—soybean (SOY) and waste vegetable oil (WVO)—blended with ultralow sulfur petrodiesel at five different volume percentages of biodiesel, Bxx (B0, B10, B20, B50, and B100).

Birmingham study finds butanol-gasoline blend reduces GDI engine-out carbonaceous emissions; similar NOx

Green Car Congress

For this reason, emission standards such as Euro 6c, which includes a strict limit of 6 x 10 11 particles per kilometer and comes into force in September 2017, are boosting the development of new technologies to reduce emissions in GDI. They found that the influence of the butanol depended on engine load. higher flame speed). Resources.
