A Study of Diesel Engine Operation with the Focus on Locomotive Characteristics

The use of control systems with electronic units in modern diesel engines provides the possibility to select engine characteristics with improved performance according to selected criteria. The article presents the results of research into the operation of an upcoming diesel engine D200 constituting a part of the power unit of a 200 kW locomotive. The research was conducted to study diesel locomotive characteristics that provided minimum fuel consumption. Based on the mathematical dynamic model of the 6-cylinder modification of the diesel in the MATLAB/Simulink software environment, a computer program was developed to calculate the steady-state regimes and transient processes. To evaluate the efficiency of the diesel engine in the range of engine operating modes, the economy and toxicity indices were calculated. A method was proposed for the formation of a diesel locomotive characteristic, the regimes of which corresponded to the operation of a diesel engine with a minimum specific effective fuel consumption. Using the developed computer program, calculations were made of the transient processes of the automatic control system when the diesel engine operated in the modes of the proposed diesel locomotive characteristics.
