Title: Study the impact of fuel and exhaust gas recirculation on HCCI combustion
Keywords: HCCI combustion, Exhaust gas recirculation, Fuel, Engine

Abstract: This paper presents a numerical study of fuel/fuel blends impact on rate of heat release at different exhaust gas recirculation rate in case of homogeneous charge compression ignition (HCCI) combustion. A direct injection engine is used for simulation which also allows mixture preparation in intake manifold leading to premixed combustion. The numerical analysis was conducted by means of an engine model developed in advanced simulation software AVL Boost. The combustion model is based on skeletal reaction mechanism of C7H16(n-heptane) that uses 26 species and 66 reactions. Additionally, to the main fuel, methane and hydrogen was added. Thus, the influence of fuel blends was evaluated at EGR rate within the range of 0% to 40%.
