Background. The paper aims at improving the operational and technical characteristics of the internal combustion engine of a locomotive running on a mixture of diesel fuel and natural gas by modernizing its information and control system.
Materials and methods. Materials and technologies are based on the implementation of fractional proportionalintegral-differential control algorithms to increase the stability and quality of transients of a multi-fuel engine.
Results. The results of the work consist in the implementation of the proposed information management system by the method of simulation and at the experimental stand. The scope includes the modernization of the control system of an internal combustion engine of a diesel locomotive.
Conclusions. The conclusions and experimental results prove the benefits of implementing the proposed control algorithm for the transition process time and the integral quality assessment in comparison with the classical algorithm, which allows reducing fuel consumption.
