Abstract

This paper deals with the mineral diesel, neat biodiesel and their blends and it discusses the influence of fuel properties on the engine characteristics with the aim to reduce harmful emissions. The considered engine is a bus diesel engine. The considered fuels are neat biodiesel from rapeseed oil and some of its blends with mineral diesel. The density, viscosity, surface tension, and sound velocity of tested fuels are determined experimentally and compared to those of mineral diesel. The obtained results are used to analyze the most important engine characteristics and tribology parameters.

Keywords

biodiesel fuel; dependence of properties on chemical structure; tribology (friction, wear and lubrication); engine piston wear
