Gunko A. Improvement of fuel economy and ecological indexes of cars in the conditions of exploitation

Dissertation is devoted to the improvement of fuel economy and ecological indexes of cars in the conditions of exploitation due to replacement of the carburetors systems of feed by the electronic distributed systems of injection of petrol. The experimental descriptions of engine of VAS-2106 with the different type of the fuel systems, which determine the explored engine as energy source, harmful emissions and fuel and air consesumer are taken. Specified mathematical model of motion of car of VAS-2106 after the modes of the European city driving cycle taking into account the features of work of the electronic distributed system of injection of petrol and his technical descriptions. Adequacy to the mathematical model by accordance of calculations and experimental results is confirmed. These results confirmed the improvement of fuel economy of ecological indexes and dynamic properties of car after the condition of replacement of the carburetors fuel system of engine by the electronic distributed system ofinjection of petrol in the conditions of exploitation. The expecting period of recoupment of charges on replacement of the carburetors fuel system by the electronic distributed system of injection of petrol is calkuletid and practical recommendations in relation to indicated replacements in the conditions of exploitation are given.
