Regulated and Unregulated Emissions Characteristics of a Diesel Vehicle Operating with Diesel/Biodiesel Blends 2007-01-0071
In the present investigation, tests were carried out to evaluate exhaust emissions of a turbocharged indirect injection diesel engine fuelled with diesel - biodiesel blends. The vehicle was Euro III compliant, fuelled with a typical diesel fuel and used frying oil methyl ester blends at proportions of 2, 5, 10, and 20% respectively. Based on the New European Driving Cycle (NEDC), regulatred and unregulated exhaust emissions were determined over a chassis dynamometer. The use of biodiesel resulted into a significant decrease of HC emissions. NOx and CO emissions exhibited a decreasing trend with the addition of the biodiesel. On the contrary, higher levels of PM emissions were observed. For carbonyl compounds, emissions of acetaldehyde were significantly increased with formaldehyde showing a slight increasing trend.
