Kuts' N. Improvement of fuel profitability and reduction of harmful emissions of automobiles by rational selection of a regulation way of petrol engines power

In the dissertation the methods of assessment of effectiveness of regulation of power of the petrol engine by switching-off of group of cylinders is developed. For realization of a methods the mathematical model of calculation of fuel consumption and harmful emissions of the lorry with the engine with switching-off of group of cylinders during movement in driving cycle is developed. The capabilities of improvement of ecological parameters of the automobile at regulation of power of the engine by switching-off of group of cylinders by directional adjustments of the fuel supply system are investigated. The optimum structures of a mixture are determined, which should be provided with the fuel supply system in modes of a driving cycle at engine run with switching-off of group of cylinders.
