Characteristics of biofuel combustion in a diesel engine

In recent years, energy indepence from petroleum fuel has been of considerable interest in agriculture. In fact, occasional tightening of standards on toxic emissions combined with rising prices for diesel fuel, force scientists to look for alternative fuels. In this article, such fuels are represented by methyl alcohol, as the main fuel, and rapeseed oil methyl ether, as the fuel that is needed for the ignition of alcohol. The paper shows the characteristics of combusting these fuels in the diesel engine 2F 10.5/12.0 under various loading conditions when using a dual fuel system. The graphs of the indicator pressure and roughness of the combustion process during the operation of a diesel engine at a frequency corresponding to the nominal operation mode and maximum torque are presented. The article presents the analysis of the obtained diagrams and conclusions on the use of the above mentioned fuels in diesel engines.
