Experimental Studies and Analysis of the Formation of Toxic Components in Diesel Engine Running on Methanol and Methyl Ester of Rapeseed Oil
摘要
The issues related to the need to improve the environmental safety of internal combustion engines and the use of alternative fuels in them are considered. A method has been proposed to reliably reduce the content of toxic components in the exhaust gases of a diesel engine by replacing standard diesel fuel with methanol and methyl ester of rapeseed oil. The results of experimental studies of the environmental parameters of a diesel engine running on methanol and methyl ether of rapeseed oil are presented, the dependences of the influence of load and speed modes of its operation on them are established, and their numerical characteristics are determined. Based on experimental data, concentrations of toxic components in the exhaust gases of a diesel engine are presented, the process of formation of total hydrocarbons CHx, carbon dioxide CO2, nitrogen oxides NOx, carbon monoxide CO, soot C in the combustion chamber is considered and analyzed in detail, and the causal relationship between the formation of toxic components in the cylinder of a diesel engine is considered., powered by methanol and methyl ester of rapeseed oil, and indicators of its workflow.
