Biodiesel and Swedish low sulfur diesel fuel as ecologically compatible fuels in modern diesel engines

Abstract

Biodiesel from rapeseed oil methyl ester is a well known substitute for fossil diesel fuel and sold at more than 1,500 filling stations in Germany. In Germany 550,000 tons biodiesel were sold in 2002. Therefore, it is necessary to observe the exhaust emissions of this alternative fuel. The objective of the research reported here was to detect and to compare regulated and non-regulated emissions together with their mutagenic effects from three different fuels. Besides biodiesel, a common diesel fuel (DIN EN 590) and Swedish low sulfur diesel fuel (SS 155435) were tested. The experiments were carried out on a state-of-the-art light duty diesel engine.
