https://doi.org/10.4467/2353737XCT.15.172.4377Requirements for better reliability, durability and effectiveness of the suggested means of transportation make the need of using state-of-the-art control systems and the system managing the work of the various vehicle components, such as the engine, brakes, etc. ABS, ASR, ESP and other systems are well known and widely used in the automotive industry. The traction control systems, eliminating the negative phenomena in the transient operation of driving systems are also met in rail vehicles. As there are no such solutions for narrow-gauge railway vehicles, including those used in mining plants, thesystem for control of operational parameters of the driving system of a mine diesel locomotive is suggested. The method for measurements of vehicle speed is indicated and use of these data in an adaptive system which adapts the operation of the driving system to the current contact conditions between wheel and rail is indicated.

https://doi.org/10.4467/2353737XCT.15.173.4378The directions of KOMAG’s investigations into diesel drives used in workings at risk of explosion are described. Two groups of research problems, i.e. the impact of a flameproof inlet- -outlet system on the engine’s operational parameters as well as identifying the phenomena in the engine regarding the emission of toxic substances with tests on improvement in the quality of exhaust gases, were specified.
