Evaluating the efficiency of the automatic speed control of a locomotive diesel
The automatic shaft speed control is one of the main systems of a locomotive diesel. Mechanical and hydro-mechanical frequency regulators used in domestic diesel engines do not always provide the required quality of control. Therefore, electronic rotational speed control systems are finding ever-widening applications. In this paper, the operation of locomotive diesel engines under various operating conditions is analyzed. An electronic rotational speed control system of a locomotive diesel engine is described. A technique for evaluating economic efficiency of this system is developed. The calculations showed that annual economic benefits of the electronic automatic control system amounted to 84 089 rubles per a locomotive.
