Journal Title: ISB-INMA TEH AGRICULTURAL AND MECHANICAL ENGINEERING - Year 2017, Vol 0, Issue 1
Abstract
Here are the results of the theoretical studies of the indications of a wheeled tractor with a gas engine in the appropriate modes of the transport process. The rational values of the parameters of the transmission and the gas engine control during the tractor acceleration and the values of the speeds of a steady movement in operating conditions according to the criteria of the minimum specific fuel consumptions and harmful emissions were selected and justified on the basis of calculations on the mathematical model of a wheeled tractor movement on a specially formed driving cycle. It was found that the maximum engine rotation range of 400...1500 min-1, the size of opening of the throttle valves is in the range of 50...60% when the speed of opening of the throttle valves to 75 %/s is optimal. Using these recommendations it is possible to achieve fuel saving up to 10 % and significantly to reduce emissions of harmful substances together with exhaust gases.
