“…Although CFR engine geometry is very simple compared to the modern SI engines, it is often used to analyze SI engine performance [45], or even used to validate the developed quasi-dimensional combustion model [46]. Once the quasi-dimensional combustion models are developed, they can be easily adopted and calibrated for the simulation of different SI engine configurations.…”

The hydrogen-enriched gasoline engine is a promising option for future spark-ignited (SI) engines. However, the lack of quasi-dimensional combustion models for hydrogen-gasoline blends restrains the efficient prediction of its performance for varying operating conditions and hydrogen enrichment strategies. In this paper, a quasi-dimensional model was developed and validated for hydrogen-enriched gasoline engines with a new laminar flame speed expression. Correspondence between the calculated and experimentally measured engine combustion parameters was observed for different hydrogen addition levels. The comparison results indicated that the proposed quasidimensional model is suitable for engine performance prediction of hydrogen-enriched gasoline engines.

“…Perini et al [21] developed a two-phase, quasi-dimensional model of a SI engine operating on LPG admixed with hydrogen and Ma et al [13] proposed a mathematical simulation of a hydrogen engine. A dual-fuel engine operating on LPG with a hydrogen admixture was modeled using equilibrium reactions by Lata and Ashok Misra [12].…”

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...
