“…Practical applications of the procedures described above are shown in this section on the example of univariate statistical analysis of maintenance efficiency economic issues of the vehicle fleet of Lublin Regional Branch of the Polish Post Logistics Centre (RB PPLC). The functioning of the national postal operators in the new EU countries is subject to various analyses [1,21,22,24,27,37,38].…”

The article presents the methods for preliminary statistical analyses of selected maintenance parameters of vehicles in road transport companies. The methodology was illustrated by presenting the results pertaining to the calculations of the maintenance intensity as well as the cost of parts and repairs of cars in the Lublin Regional Branch of the Polish Post Logistics Centre. These results provided comparative material useful in the evaluation of the maintenance efficiency of various road transport systems.

“…Environmental impacts of means of transport are unfavorable and often have unavoidable character [3,4]. Problems of noise pollution [5][6][7] and emissions from transport are the subject of many scientific studies [8][9][10][11][12][13]. The transportation problems related to traffic accidents and collisions represent a constant problem undertaken by the many researchers, as evidenced by numerous publications in this field, for example [14][15][16][17].…”

The insertion of a city bike that complements the public transport system in large agglomerations, and mainly in the most crowded city centers, seems to be a very good solution that can contribute to reducing air pollution and reducing noise levels. In many situations, bicycle transport can perfectly fill deficiencies in public transport, e.g. at night, on holidays and on days when buses run to a limited extent. The article presents the functioning of the city bike system in Lublin since 2014. The first part of this article presents basic data on the city bike system in Lublin together with a map of bicycle stations, followed by data on the number of rentals, rental time, number of bicycle users, etc. Selected user opinions obtained on the basis of the survey were also presented. Finally, based on the analysis, final conclusions were formulated. The city bike system is used by about 10% of the population of the city of Lublin.

“…The current research on compression ignition combustion engines is primarily oriented towards the use of alternative renewable fuels, reduction of toxic air emissions and the development of new engine diagnostic methods [5,6,15]. One of the increasingly often-addressed problems in engine research is the possibility of dual-fueling engines with the main fuel charge fed as a gaseous fuel.…”

The problem of using alternative fueling sources for combustion engines has been growing in importance recently. This is connected not only with the dwindling oil resources, but also with the growing concern for the natural environment and the fight against global warming. This paper proposes the concept for a zero-dimensional model of a multi-fuel engine, enabling the determination of thermodynamic system parameters based on the basic geometric and material object data (complete model). The basic problems in the creation of this model and the modeling of the accompanying subprocesses have been outlined and the methodology of the numerical solution of the obtained mathematical description has been proposed. The basic characteristics of the developed model are: the application of an original model of liquid fraction injection based on normal distribution, a new Assanis correlation for computing the diesel fuel self-ignition delay period in the presence of gas, first-order chemical reaction kinetic equations for describing the course of combustion for combustible components of the gas/air mixture, the implementation of a self-consistency procedure in modeling heat exchange and the effect of exhaust recirculation, the inclusion of both a single liquid fuel injection and the possibility of performing computations for a divided charge. Keywords: dual-fuel engine, engine combustion process, mathematical model, computer simulation, heat exchangeW ostatnim czasie problem wykorzystania alternatywnych źródeł zasilania silników spalinowych zyskuje szczególnie na znaczeniu. Związane jest to nie tylko z kurczącymi się zasobami ropy naftowej, ale również z coraz większą troską o środowisko naturalne oraz walką z globalnym ociepleniem. W niniejszej pracy zaproponowano koncepcję zero-wymiarowego modelu silnika wielopaliwowego, umożliwiającego, wyznaczenie parametrów termodynamicznych układu w oparciu o podstawowe dane geometryczne i materiałowe obiektu (model kompletny). Nakreślono podstawowe problemy w zagadnieniu tworzenia takiego modelu i modelowania podprocesów towarzyszących oraz zaproponowano metodykę numerycznego rozwiązywania uzyskanego opisu matematycznego. Podstawowe wyróżniki opracowanego modelu to: zastosowanie autorskiego modelu procesu wtrysku frakcji ciekłej opartego na rozkładzie normalnym, nowej korelacji Assanisa do obliczenia okresu zwłoki samozapłonu oleju napędowego w obecności gazu, jednostopniowych równań kinetyki reakcji chemicznej do opisu przebiegu spalania składników palnych mieszaniny gaz-powietrze, implementacja procedury samouzgodnienia w modelowaniu procesu wymiany ciepła i wpływu recyrkulacji spalin, uwzględnienie zarówno pojedynczego wtrysku paliwa ciekłego jak i możliwość prowadzenia obliczeń dla dawki dzielonej.Słowa kluczowe: silnik dwupaliwowy, proces spalania w silniku, model matematyczny, symulacja komputerowa, wymiana ciepła.Mikulski M, Wierzbicki s, PięTAk A. zero-dimensional 2-phase combustion model in a dual-fuel compression ignition engine fed with gaseous fuel and a divided diesel fu...
