Osetrov O. Improvement of the efficiency of the diesel 4 CHN 12/14 running on biofuel

Four-cylinder the autotractor injection engine 4CHN12/14 with a direct injection injection of the fuel, working on vegetable biofuels. Martempering of technical-and-economic indexes of the injection engine 4 CHN 12/14 at the expense of sampling rational parameters of working process. Methods of definition of output indexes of the injection engine with use of the state-of-the-art equipment; a method of the analysis of indicator diagrams; calculated methods of definition of indexes of combustion processes, formations of an oxide of nitrogen and black; a calculated method of definition of complex criterion of fuel profitability and toxicity of completing gases. The complex mathematical model of working process of the injection engine working on biofuels is developed. For the first time equilibrum compositions, thermal capacities and enthalpy of products of combustion of biofuels are calculated. The technique of a comparative estimation of efficiency of application in the injection engine different is offered and the biofuel, which use in the injection engine 4 CHN 12/14 is defined is the most effective. The equation for an evaluation of complex ecological criterion is inoculated and the dependences linking this criterion, indexes of fuel profitability and toxicity of completing gases of the injection engine with compression ratio, a boost pressure, an advance angle and duration of an injection Results of operation are obtained are introduced in KP "HКBD"; in problem research laboratory of faculty DVS NTU "KhPI". An engine building.
