Abstract
To solve the problem of oil deficit and reduce emissions of harmful substances from exhaust gases of vehicles alternative motor fuels, including biodiesel may by used. Most of wheel tractors are used as technological transport in agriculture, industry and municipal services. The article aims to clarify the mathematical model to determine the effect of the type of fuel used wheeled tractors on its performance. The mathematical model of the system "operator-wheel tractor-road" for the design research impact type of fuel on harmful emissions and fuel consumption wheeled tractor, is used as technological transport during its movement for driving cycle. Driving cycle showed main modes of motion there are acceleration, motion with constant speed and deceleration. The mathematical model allows to accurately consider peculiarities of the wheel tractor as the vehicle and engine describing its characteristics by polinomial dependencies. In mathematical models specified polynomial dependences that describe the fuel supply cycle indicated torque, fuel consumption and concentrations of main harmful substances in the exhaust gases of diesel during operation on diesel and biodiesel.
