Simulation Modeling of a Hybrid Diesel Locomotive Power Plant Based on a Free-Piston Engine

The article is devoted to the results of studies of a simulation model of the hybrid diesel locomotive power plant electric drive, which consists of a free-piston internal combustion engine with a linear generator of electromagnetic type, energy storage and an electronic commutator. The functional diagram of a free-piston internal combustion engine with a linear generator of electromagnetic type works in two strokes (compression and piston) was built. The simulation model was made based on a functional diagram, a free-piston internal combustion engine with a linear generator of an electromagnetic type block diagram. The model has been tested on the Kharkiv - Borki road sections of 44.5 km with an average speed of 40 km/h and a train's weight of 600 tons. The analysis of the results of the simulation showed that the fuel consumption was 44.8 kg, which is 9% less than in traditional systems. Results of modelling show that the system with a free-piston internal combustion engine with a linear generator of electromagnetic type is a promising direction for the development of mechanical engineering.
