The spark-assisted ignition homogeneous charge compression ignition(HCCI) combustion refers to an intermediate combustion mode between pure HCCI and conventional spark-ignition combustion. Using a single cylinder research gasoline engine equipped with fully variable valve actuation, the characteristics of SI-HCCI combustion mode transition process of spark-ignition were investigated. Based on the systematic analysis of the characteristics of heat release rate, the model of hybrid heat release rate was proposed. And the corresponding computing model was also established in the light of the influence of spark ignition timing and residual rate; therefore, it provides significant theoretical basis and technological methods for the research of the control strategy in SI-HCCI mode transient.
