It has been experimentally established that the modification of the spray nozzle structure of the diesel fuel injector due to the reduction of the length from 18 mm to 10 mm and the diameter from 6 mm to 4 mm of the precision guide, the increase in the diameter of the needle rod to increase its rigidity, the development of the cooling cavity under the differential needle pad increasing the number of fuel supply channels from 3 to 5, increasing the fuel injection pressure from 21–22 MPa to 27–28 MPa and reducing the needle stroke from 0.45 mm to 0.35 mm affects the power and economic parameters of tractor dies spruce. The use of experimental sprayers in a tractor diesel with gas turbine supercharging makes it possible to reduce the specific fuel consumption by 2–6 g/kW h and the temperature of the exhaust gases by 30–50 °C depending on the loading regime, as well as some increases (up to 2%) the coefficient of adaptability for torque. Using sprayers of experimental design in diesel with gas turbine supercharging allows to reduce the specific effective fuel consumption by 2–6 g/kW h and exhaust gas temperature by 30–50 °C depending on the loading mode, also some increase (up to 2%) of the coefficient of adaptability for the torque is registered.
