The economic performance of diesel engine when operating on methanol with a dual fuel supply system

Abstract

Limited reserves of fuel of oil origin and a significant increase in the price of oil and its products have made the work aimed at finding and justifying the use of alternative fuels relevant. Among the latter, methanol occupies an important place, for the production of which raw materials are available on a large scale. Methanol can be obtained from natural gas, coal, biomass, or urban waste. Methanol can be attributed to renewable energy sources. It should be noted that the development of a fundamentally new engine model that meets modern environmental and economic requirements requires long-term research and high material costs, so our research is aimed at upgrading commercially available engines. The article presents the results of implementing a method for using methanol by feeding it directly into the combustion chamber and igniting it from the igniting part of diesel fuel. The economic indicators of the developed diesel engine when working on methanol under different load conditions are analyzed.
