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...

“…Thus, hydrogen is hard to burn with air in a compression ignition engine. However, in this case the spark plug aids the ignition of the hydrogen-air mixture which solves the major problem [6,7] . As mentioned earlier, the ignition delay may cause the peak pressure to reduce which results in IMEP decrease since the work done through the control volume is less [8] .…”

Active research and development on hydrogen-fuelled engine had been done for few decades since hydrogen serves as a potential of infinite fuel supply. This paper discussed analytically and provides data on effects of compression ratio, equivalence ratio and spark timing of a hydrogenfuelled engine as a guideline for the engine design. The change in thermodynamic properties of the fuel was considered through the engine cycle. A modified version of Olikara and Borman method was presented to track the mole fraction of the equilibrium state of combustion products for hydrogen fuel.The equilibrium values of each species were used to predict the NO x formation, which is the main concern of study for hydrogen-fuelled engine.

Homogeneous charge compression ignition (HCCI) engine combines the combustion characteristics of a compression ignition engine and a spark ignition engine. HCCI engines take advantage of the high compression ratio and heat release rate and thus exhibit high efficiency found in compression ignition engines. In modern research, simulation has be come a powerful tool as it saves time and also economical when compared to experimental study. Engine simulation has been developed to predict the performance of a homogeneous charge compression ignition engine. The effects of compression ratio, cylinder pressure, rate of pressure rise, flame temperature, rate of heat release, and mass fraction burned were simulated. The simulation and analysis show several meaningful results. The objective of the present study is to develop a combustion characteristics model for a homogeneous charge compression ignition engine running with isooctane as a fuel and effect of compression ratio.
