Charcteristics of heat release in the disel engine running on biofuel

Abstract

Abstract Research aimed at finding new alternative fuels is becoming more and more urgent with each day, due to depletion of the world’s oil deposits and pollution of the atmosphere with toxic emissions of exhaust gases produced by the internal combustion engine. The article below describes the results of using alternative renewable fuels, such as methyl alcohol and methyl ether of rapeseed oil and their effects on the process of heat generation in diesel engine under various load conditions. The object of research is a 2F 10.5/12.0 engine with a dual fuel supply system installed on it. The obtained results showed that the optimal fixer advance angle of fuel injection is equal to 34° to the top dead centre for both types of fuel. The use of alternative fuels does not significantly affect the operational process. At the same time, it was noted that emissions of toxic agents, such as nitrogen oxides and soot, have significantly decreased.
