Homogenous Charge Compression Ignition (HCCI) combustion is a promising concept to reduce engine emissions and fuel consumption. In this paper, a thermo-kinetic single zone model is developed to study the operation characteristics of a natural gas HCCI engine. The model consists detail chemical kinetics of natural gas oxidation including 325 reactions with 53 chemical species, and is validated with experimental results of reference works. Then, the influence of parameters such as manifold temperature/pressure, and equivalance ratio on incylinder temperature/pressure trends, start of combustion and heat release rate is studied. These results are explained in detail to describe the engine performance thoroughly.

Zaletą silników wysokoprężnych o spalaniu homogenicznym (HCCI) jest możliwość zmniejszenia emisji związków toksycznych i zużycia paliwa. W artykule przedstawiono termokinetyczny jednostrefowy model silnika HCCI zasilanego gazem ziemnym. Model zawiera 325 reakcji chemicznych utleniania i jest skorelowany z wynikami doświadczalnymi uzyskanymi w innych badaniach. Przeanalizowano wpływ na pracę silnika takich parametrów, jak: temperatura i ciśnienie dolotu, współczynnik nadmiaru powietrza w cylindrze, zmiana temperatury i ciśnienia w cylindrze oraz początek zapłonu i szybkość wywiązywania się ciepła. Opisano rezultaty doświadczeń i ich wpływ na pracę silnika.
