Improving the environmental parameters of diesel engines when they are transferred to methanol conversion products

Abstract

The article aims to solve the problem of converting existing automobile diesel engines to gas fuels, which are a cheaper and more environmentally friendly alternative to diesel fuel. Method of increasing energy of alternative fuels was improved. Chemical essence of fuel energy increase is considered on the basis of scientific provisions of thermodynamics. As a starting point for the conversion process, an alternative methanol fuel was selected, taking into account its cost, environmental friendliness and temperature conditions. The calculations showed that thermal effect from combustion of the converted mixture exceeds the effect from combustion of the same amount of non-convertible methanol. Fuel energy increased due to thermochemical regeneration of exhaust gas heat. An experimental setup has been created to study the operation of a converted diesel engine at methanol conversion points. Experimental studies of environmental performance of a diesel engine, which was converted to work at methanol conversion points. Experimental studies have shown that the conversion of diesel engines to work using methanol conversion points is technically justified. Reduction in fuel consumption was accompanied by an improvement in the environmental performance of the diesel engine, which works in conjunction with a thermochemical methanol conversion reactor. Depending on the speed of the crankshaft and the load on the engine, the formation of nitrogen oxides in the exhaust gases decreased by 53-60%, carbon monoxide occurred in the range of 52-62%. Given that the price of methanol is up to 20% of the cost of diesel fuel, the conversion of automotive diesel engines to work using methanol conversion points is very profitable.
