The basic principle of plasma enhanced combustion is introduced. Three ways of plasma enhanced combustion are summarized, which are thermal strengthening, dynamic strengthening and transport strengthening respectively. The application verification of plasma enhanced combustion in the world, especially in China, Mechanism and numerical simulation research are summarized.The four research directions of plasma enhanced combustion are proposed, which are plasma enhanced combustion mechanism, multi-field coupled modeling and simulation, test diagnosis research, and plasma In the meantime, some suggestions for carrying out these four aspects of research work are put forward. The main contributions of this study are to quantitatively study the three effects of plasma ignition and combustion, and establish the respective effects and ignition characteristics, Combustion characteristics of the relationship between the establishment of detailed plasma enhanced combustion dynamics model; the application of advanced test diagnostic equipment, the development of plasma enhanced combustion of new testing techniques; consider the plasma ignition and combustion when applied to different types of engine combustion chamber Matching problems, especially the miniaturization and light weight of plasma power supplies Problems and so on.
