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). to 13.6 ± 3.8
