The effect of fuel equivalence ratio on the autoignition and combustion processes in a Homogeneous Charge Compression Ignition (HCCI) engine has been studied using a primary reference fuel (PRF60). Experiments have been performed on a single-cylinder engine operated in an alternate-fire mode. The operating conditions of the engine used in this work were an intake air pressure and temperature of 1.5 bar and 75°C respectively, an engine speed of 1200 rpm, compression ratio of 12:1, with varying fuel equivalence ratio (φ). A single zone CHEMKIN model using reduced chemical kinetic model of 560 species and 2818 reactions based on a 5 components gasoline surrogate from Reaction Design's Model Fuels Consortium was used to predict the HCCI engine combustion behavior for different fuel equivalence ratios.
