Abstract: In this study, an energy conversion device referred to Confined Piston Linear Generator (CPLG) is proposed. Moreover, a modeling approach which takes the time-varying and non-linear factors into account is presented to build a real-time integrated model of the CPLG system. The Internal Combustion Engine (ICE) and Permanent Magnet Synchronous Linear Generator (PMSLG) model were built by GT-Power and Maxwell respectively, as well as the date transformation between them was realized by Simulink. The results indicated that, the shutdown areas of the PMSLG are located in the region of low load, low speed or low external load resistance. As the rise of external load resistance, the shutdown area A exists in the conditions of low load, and gradually moves to the high-speed region and reduces or even disappears, while the shutdown area B appears in the low-speed region and expands to the high-speed region. Within the operating area of the PMSLG, the energy conversion efficiency of the CPLG system is improved by 2.32% compared with the prototype ICE. In respect of parameter analysis, the influence of intake pressure on output power is much greater than those of ignition timing, air-fuel ratio and compression ratio.
