Power Engineering and Engineering Thermal Physics

Power Engineering and Engineering Thermophysics is a primary discipline that serves as an engineering foundational and applied technological science. It takes the efficient and clean development, production, conversion, and utilization of energy as its application context and ultimate goal. It focuses on studying the fundamental laws governing the conversion and transfer of energy during processes where energy in forms such as heat, light, potential, and kinetic energy is converted into work, electricity, etc., or vice versa. It also encompasses the theory and technology for the effective design, manufacture, and operation of equipment and systems that realize these processes according to these laws. It constitutes the theoretical foundation for Energy and Power Engineering.

The Power Engineering and Engineering Thermophysics primary discipline at Beijing Jiaotong University cultivates postgraduates in three secondary disciplines: Power Machinery and Engineering, Engineering Thermophysics, and Thermal Power Engineering. Through years of development and addressing major national needs in the energy and power sector, it has formed seven distinctive research directions:

1. Internal Combustion Engine Combustion and Emission Control

2. New Energy Power Systems and Control
