Дослідження впливу завантаження автомобіля на витрату палива при використанні системи живлення двигуна зі зміною складу суміші дизельного та біодизельного палив

Abstract

The paper presents the results of the calculation of fuel consumption KrAZ-6510, equipped YaMZ-238, depending on the load the vehicle powered by diesel fuel, biodiesel, a mixture B25, B50, B75 and using the power supply system of the diesel engine car to change the fuel mix. Power system motor with a change of mix allows you to change the mix of fuels while driving, depending on its load and conditions.

The object of study - the fuel consumption of the vehicle when powered by diesel fuel, biodiesel, a mixture B25, B50, B75 and using power system with the changing composition of the mixture.

Purpose - to determine the effect of loading on vehicle fuel consumption when powered by diesel, biodiesel, a mixture B25, B50, B75 and using power system with the changing composition of the mixture.

Found that with the use of diesel power with the change of fuel mixture while driving KrAZ-6510 for the main loop road without load fuel mixture flow increased by 12,01% when driving with a load of 6000 kg - at 11,15% and 12000 kg - on 9,94%, this is due to a greater proportion of biodiesel in mixture.

Thus, the use of diesel power system with the changing composition of the mixture of diesel and biodiesel largest proportion of biodiesel in the mixture occurs while driving with a low load or no load. In this case, achieved the greatest economic benefit, through lower cost of biodiesel.
