Particle number emissions from a light-duty vehicle diesel engine during transient state operating conditions were studied. Test fuels were petroleum diesel, pure Jatropha biodiesel, B20 and B50 biodiesel blend fuels. The results show the number of nucleation mode particles from the engine increases when using petroleum diesel during the transient operating condition (Increasing torque at constant...
This study investigated the emission characteristics of ultrafine particles based on test bench and on-board measurements. The bench test results showed the ultrafine particle number concentration of the diesel engine to be in the range of (0.56–8.35) × 10 8 cm −3 . The on-board measurement results illustrated that the ultrafine particles were strongly correlated with changes in real-world...
Experimental studies on global warming potential (GWP), photochemical ozone creation potential (POCP), acid potential (AP), health toxic potential (HTP), and air quality potential (AQP) of an common rail diesel engine fueled with wasted oil based biodiesel blends were carried out. The results shown that when the engine fueled with wasted oil based biodiesel blends, its POCP and AQP are lower than...
