The article presents the results of computer modeling and experimental research of the effect of butanol content in the fuel on the specific power, fuel-economic and environmental performance of 4ЧН 11/12.5 (4ChN 11/12.5) diesel engine at various cycle fuel supplies and exhaust gas recirculation rates. The research has been carried out at crankshaft speeds of 1,000, 1,200, 1,400, 1,600, 1,800, 2,000 and 2,200 rpm with 25, 50, 75 and 100 % load. Fuels with butanol content of 5, 10, 15, 20, 25, and 30 % by volume have been investigated. The computer model of the diesel working process has been developed that takes into account the physical and chemical properties of the fuel, the characteristics of the fuel flow in the nozzle tip and the development of fuel sprays in the combustion chamber. Based on the results of computer modeling, dependencies have been determined that make it possible to assess the effect of the percentage of butanol in mixed fuel on the mean indicator pressure, specific fuel consumption, indicator efficiency, emissions of nitrogen oxides and dynamic indicators of the combustion process when choosing the composition of mixed butanol-containing fuel. Based on the conducted research, the following composition of mixed fuel has been selected: 85 % diesel fuel and 15 % butanol. Comparative tests of the diesel engine have been carried out when working on the external speed characteristic on diesel fuel and its mixture with 15 % butanol. It is obtained that when using mixed fuel, the character of the power change remains unchanged, the exhaust smoke decreases, nitrogen oxides emissions decrease at crankshaft speeds of 1,400, 1,600, 1,800, and 2,200 rpm, and the effective engine efficiency remains practically unchanged.
