Problem. The problem is that in Ukraine and in the world today there is an urgent multifaceted problem of meeting the demand for road transport in cheap and environmentally friendly fuel, not of oil origin. Goal. The goal of this article is experimental study of:
- changes in the power characteristics of automobile diesel engines when used in these engines of methanol, which is obtained from elode;
- changes in the environmental performance of automotive diesel engines when used in these engines of methanol, which is obtained from elode. Methodology. At the first stage, parameters of the engine, which worked on diesel fuel, were investigated. At the second stage, the compression ratio was reduced to 14.1 by removing the head of the block and installing two additional gaskets under the head. Next, the engine parameters that worked on methanol were studied. Results. The experimental dependences of the effective power N and the specific fuel consumption ge on the crankshaft rotational speed n for the base diesel and the methanol-converted engine are investigated. Experimental dependencies of the content of hydrocarbons CnHm and carbon monoxide CO on the rotational speed of the crankshaft engine n for the base diesel engine and converted to methanol; Experimental dependences of the content of NOx and carbon dioxide CO2 on the crankshaft rotational speed of the engine n for the base diesel engine and the methanol-convertible. Originality. The obtained results allow to optimize the choice of fuels for power systems of internal combustion engines and to reduce emissions of harmful substances in exhaust gases of automobile diesel engines. Practical value. When transferring a diesel engine to operation on methanol there is no reduction of power engine parameters; the analysis of the exhaust gases during the transfer of the diesel engine to work on methanol shows that in all modes of operation of the engine there is a reduction in emissions of nitrogen oxides (up to 54%) and carbon monoxide (up to 89%).
