In Poland, the number of vehicles owned per capita is systematically increasing. There is also a noticeable increase in traffic in large urban agglomerations. This creates a number of problems, such as difficulties in finding a parking spot. Then it becomes necessary to search for a long time to stop, which is correlated with higher emission of harmful substances and energy consumption. The aim of the work is a multi-criteria analysis of the selection of a parking spot at a shopping center focused on travel times, pollutant emissions and fuel consumption. In addition, consideration was given to the selection of the optimal parking spot. The tests were carried out in Real Driving Conditions similar to Real Driving Emissions testing. The procedure, currently used as an extension of the type-approval tests, reflects the actual exhaust emissions from vehicles more accurately than tests under laboratory conditions. Specialized PEMS (Portable Emissions Measurement System) apparatus was used for the measurements.

Kontrola zużycia energii potrzebnej do poruszania się pojazdu po określonej trasie jest ważnym aspektem w eksploatacji środków transportu. Celem niniejszej pracy jest analiza zużycia energii dwuczłonowego pojazdu elektrycznego z zasobnikiem energii podczas symulowanego przejazdu teoretycznego na uprzednio wybranej trasie testowej. Projekt pojazdu został zrealizowany przez Sieć Badawczą Łukasiewicz – Instytut Pojazdów Szynowych „TABOR” oraz H. Cegielski – Fabryka Pojazdów Szynowych. Wyposażenie zespołu trakcyjnego w zasobnik energii pozwala na łączenie tras zelektryfikowanych oraz niezelektryfikowanych. W pracy ujęto algorytm obliczeń, rozpływ energii w pojedzie, parametry przejazdu oraz opis trasy testowej. Uzyskane wyniki pozwoliły na wyznaczenie m.in. minimalnej niezbędnej pojemności zasobnika energii do pokonania analizowanej trasy.

The control of energy consumption needed to move a vehicle along a specific route is an important aspect in the operation of means of transport. The aim of this study is to analyse the energy consumption of a two-unit electric rail vehicle with an energy storage during a simulated theoretical ride on a previously selected test route. The vehicle design was carried out by the Łukasiewicz Research Network - Institute of Rail Vehicles «TABOR» and H. Cegielski - Factory of Rail Vehicles. Using an energy storage allows the connection of electrified and nonelectrified routes. The work includes the calculation algorithm, energy flow in the vehicle, ride parameters and a description of the test route. The obtained results allowed for the determination of, inter alia, the minimum necessary capacity of the energy storage to cover the analysed route.

Track works typically require the use of special-purpose rail machines, in which the main source of propulsion includes high-power compression ignition engines. Reliance on these types of engines, which are characterized by a significant degree of wear and tear, relates to relatively high specific fuel consumption and the exhaust emissions of toxic compounds. Using such rail machines to perform modernization and repair works has a negative impact on the natural environment. The article presents test results of toxic compounds exhaust emissions as measured from a special purpose rail machine. The tested vehicle was a machine designed for profiling the ballast cess labeled as PŁT-500. The machine was classified as NRMM (Non Road Mobile Machinery) as well as used for profiling and cleaning the cess. A PEMS (Portable Emissions Measurement System) type apparatus was used for the emissions measurement. This made it possible to measure the exhaust emissions as RDE (Real Driving Emissions) of toxic compounds from the machine under real operating conditions. The obtained test results include the measured exhaust emissions of gaseous compounds: CO, CO2, HC and NOx as well as the vehicle fuel consumption while performing its track works.

The article presents an innovative solution of a two-unit rail vehicle system for passanger transport with a dual-drive, diesel engine and electric motor. The vehicle was designed as a combination of two units, one dedicated to each of the two drive systems, where one unit provides electric drive while the other a combustion engine. The selection of engine and drive components was presented along with the aftertreatment systems used in the design. The provided solution was created in response to the dynamic needs of rail vehicle operators in the European Union who aim to reduce exhaust emissions without compomising the reach of the existing rail networks.

The article presents the results of a simplified analysis of the feasibility of designing a rail chassis of a two-way tractor with an internal combustion or electric drive. Basic traction and operating parameters have been assumed for which the road-rail tractor could operate in an effective manner. On their basis, strength calculations were carried out and mechanical elements of the drive system meeting the required assumptions were selected. All the calculations presented in the text were fulfilled. The technical feasibility of building the mechanical part of the rail running gear of a rail-road tractor driven by an internal combustion engine or electric motors has been demonstrated.
