The significant cost of diesel fuel, limited reserves of oil and natural gas have made the work aimed at finding and justifying the use of alternative fuels relevant. Alternative fuels include methanol, which can be obtained not only from natural gas and coal, but also from bi-omass 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 indicator indicators of the developed diesel engine when working on methanol at different angles of injection of diesel fuel and methanol are analyzed. Optimal installation angles of fuel injection are selected and justified.
