Application of ethanol fuel emulsion in diesel engines

Abstract

Abstract The article analyzes experimental data obtained during bench tests of tractor diesel 4CH 11.0/12.5 using alternative fuelethanol. Ethanol was supplied to the diesel cylinder as part of an emulsion, this method allows for minor modifications of the diesel fuel system to use alternative fuel with a sufficiently high efficiency. In the Vyatka state agricultural Academy on the basis of the Department of heat engines, cars and tractors, a diesel engine was developed to work on ethanol-fuel emulsion. The article substantiates the possibility of establishing the maximum permissible concentration of ethanol in the emulsion for this diesel, it is 25% of the total fuel and provides sufficient conditions for the organization of a stable combustion process without skipping ignition. The article presents experimental studies of the working process of diesel when working on ethanol-fuel emulsion, which were brought to the maximum.
