Study on the Characteristics of Emissions from Light Duty Vehicle Fueled with Biodiesel under Transient Operating Mode

Abstract:

Biodiesel is a renewable and clean alternative fuel. The exhausts emissions from light duty vehicle fueled with biodiesel and No.0 diesel fuel are measured and analyzed. The modular features of emissions under transient operating mode is investigated on. As compared to No.0 diesel fuel, experimental results show that the HC and CO emissions of cold start are improved much from light duty vehicle fueled with biodiesel and also the specific emissions of HC, CO and PM decrease 62.0%, 42.5% and 46.2% respectively, but the NOx specific emission rise 7.1% up. Chemical energy is released during the combustion of fuel, which produced CO2 and H2O, at the same time the N2 in air would also be oxygenated to NOx. So the concentration rate of NOx/CO2 is used to describe the regularity of NOx emission with the transient operating mode.
