According to the boost mathematical model verified by experiments, the valve train of traditional gasoline engine is optimized and improved to achieve extended expansion cycle. The simulation results of extended expansion gasoline engine shows that the extended expansion gasoline engine has a better economic performance, compared to traditional gasoline engines. The average brake special fuel consumption (BSFC) can reduce 22.78 g / kW•h by LIVC, but the negative impacts of extended expansion gasoline engine restrict the potential of extended expansion gasoline engine. This paper analyzes the extended expansion gasoline engine performance under the influence of LIVC, discusses the way to further improve extended expansion gasoline engine performance.

Modern hydrocarbon adsorbers for gasoline engines are promising candidates for cold start emission control. In this paper, the flow and heat transfer in a typical complex system, comprising a “barrel type” adsorber and two conventional catalysts is studied. A mathematical model is developed and applied for the computation of the flow and pressure distribution, as well as transient heat transfer in the system. The model is aimed at understanding and quantifying the particular thermal response behavior of hydrocarbon adsorber systems. Illustrative results with variable geometric parameters under realistic input conditions are presented. [S0742-4795(00)01701-4]
