Improvement of fuel and economic characteristics of diesel engines by their converтing to methanol conversion gas products
DOI: 10.33868/0365-8392-2022-1-269-2-13

Abstract. The work is aimed at solving the problem of conversion of existing diesel power drives of technological transport into gaseous fuels, which are a cheaper alternative to diesel fuel. A method has been proposed to increase the energy efficiency of alternative fuels. The thermochemical essence of increasing the energy of the source fuel has been developed. The choice of alternative alcohol fuel as a starting product for the conversion process, taking into account its cost and energy value. The calculations showed that the thermal effect from the combustion of converted CO and Н2 exceeds the effect from the combustion of the same amount of liquid methanol. Fuel energy and engine power were increased by regenerating the heat of the exhaust gases. Experimental studies of power and economic performance of a diesel engine, which was converted to work on the products of methanol conversion. Experimental studies have shown that the conversion of diesel engines to work using methanol conversion products is justified. Given that the price of methanol is, on average, 10-20% of the cost of diesel fuel, the conversion of diesel engines to work using methanol conversion products is quite profitable.
