Investigation of biofuel combustion process in direct injection diesel engine

Abstract

In contemporary transport sector and especially in the agricultural production, there is a large possibility of using alternative engine fuels. In the case of agricultural applications, the largest number of agricultural machinery's propulsion engines is diesel, which allows the use of various vegetable oils as propellants. However, this implies that these vegetable oils have been treated by appropriate esterification procedures and adapted for smooth use in engines. Such fuels are generally called biodiesel as well. This paper will present some results of an investigation of the combustion process of rapeseed methyl ester of a single-cylinder direct injection diesel engine designed to drive smaller agricultural machinery, thus engines. The results of the research are presented in the variant of the charged engine, whereby the charging process was performed by an external energy source (electromotor and Roots compressor) under laboratory conditions.
