Wei Yanju, Doctoral Supervisor, Associate Professor of Xi’an Jiao Tong University, China.

His main research direction is on the combustion and emission fundamentals of clean fuel engines, including emissions and control, working process numerical simulation, engine performance development, fuel spray, droplet combustion, methanol cracking hydrogen production, etc. He has presided over 1 major research program (general) project of the National Natural Science Foundation of China (NSFC), 2 General projects, 1 youth project, and 2 key research and development programs of Shaanxi Province. The engine design, performance development, emission regulation technical route, and combustion mechanism of methanol, ethanol, dimethyl ether, PODE, and other clean fuels in methanol engines have been systematically carried out, solving a series of key scientific and technical problems faced by carbon neutral fuel engine. The research has published over 80 papers including top journals such as Applied Physics, Journal of Fluid Mechanics, Applied Energy, Fuel, and Physics of Fluids, and authorized 7 invention patents. Currently, he is a director of the China Internal Combustion Engine Society, a member of the China Internal Combustion Engine Industry Association, Vice President and Secretary General of Shaanxi Internal Combustion Engine Society and a young editorial board member of the journal “Internal Combustion Engine Engineering”.
