POSSIBILITIES OF REDUCING SPECIFIC FUEL CONSUMPTION BY IMPROVING THE TECHNICAL CONDITION OF TIRES AND AXLE SEMI-TRAILER TRUCKS
The article analyzes the factors influencing the rolling resistance of tires: types of installed tires; pressure in them; the total mass of the road train; driving style. The dependence of the specific fuel consumption (SFC) on the listed factors has been studied. It has been substantiated that the installation of radial tires instead of diagonal tires allows reducing the SFC by 6-10%, reducing the pressure in the tires of a loaded road train, for every 0,44 bar. from the normative, increases the SFC by 1%, the maximum displacement of the axles of the road train increases the SFC by 2-3% and reduces the service life of the tires.
