The improvement of agricultural machinery dynamic characteristics using particular types of alternative fuel
Journal Title: Наукові горизонти. Scientific Horizons - Year 2018, Vol 67, Issue 4
Abstract
The change of external work indexes in refitted engines that can be installed on agricultural trucks, using particular types of alternative fuel (water-fuel emul-sion, generator gas) causes the change of dynamic characteristics, as it was inves-tigated according to the conditions of agricultural production. Using the calculat-ed dynamic characteristics it is possible to solve tasks directed at determination of agricultural machinery dynamics. The analysis of ZMZ-53 engine simulation results using the alternative fuel mentioned above shows, that the change of crankshaft rotation speed in the mode of maximum torque does not exceed 10%, that is, while approximating the engine torque it is possible to use one and the same polynomial. It is stated, that the calculated coefficient shows how it is necessary to change the transmission ratio of GAZ-SAZ-25041 that works on alternative fuel in order to make dynamic indexes equal to the basic (petrol) modification. In the GAZ-SAZ-25041 working on generator gas, the coefficient rate will correspond to =1,411, on water-fuel emulsion – =1,332. While the necessary transmission ra-tio can be provided either with an additional gearbox with installed ratio, or by the main transmission, which transmission ratio is in times exceeds the one of basic model. On the basis of feasibility assessment, further multifactorial experimental inves-tigations of modernized transmissions refitted to the agricultural machinery, using alternative fuel are advised.
