Formation of Driving Torque of Engine in the Technological Transport Machine with Multiphase Injection of Fuel

This research analyzes the formation of the torque of the engine of transport and technological vehicles with the mechatronic control system. The influence of multiple injection of diesel fuel with the system "Common Rail" on the unevenness of the engine is considered. Calculations of thermodynamic parameters of the engine working process are performed on the basis of the three-phase fuel injection oscillogram taken using the simulator stand "Car Train Common Rail system". The results of the calculation determine the coefficient of uneven torque for the engine of the prototype with the classic single-phase injection and engine with multiple fuel injections. It is found that the engine with multiple fuel injection coefficients of the unevenness of the torque is close to the value for six-cylinder engines, characterized by perfect balance. With the decrease of the coefficients of uneven torque, conditions of operation of the engine generally improves, the vehicle is better after the wear of their parts due to the weakening of the shock load and vibrations is reduced and as a result, the engine works noiselessly.
