Yang Langjian is an emerging scholar specializing in vehicle powertrain systems, with strong expertise in cold-start mechanisms, environmental adaptability, and electronic-control optimization of internal combustion engine equipment under high-altitude and extremely cold conditions. With a research portfolio comprising 7 published documents, 33 citations, and an h-index of 4, he has demonstrated impactful and steadily growing academic influence in the field. As first author, he has contributed extensively to top-tier SCI journals, producing high-quality work on mixture formation, ignition and combustion mechanisms, fuel-injection strategies, and the dynamic evolution of cold-start processes in both diesel and aviation piston engines across variable altitude and temperature environments. His research achievements include multiple Q1 publications, EI-indexed studies, and widely recognized conference contributions, supported by rigorous experimental design, simulation modelling, and advanced numerical analysis using platforms such as CONVERGE, AVL-Fire, AVL-Excite-PR, GT-Suite, Fluent, Hypermesh, and Abaqus. He has participated in and led numerous national, provincial, and industry-funded research projects, contributing to key advancements in thermal management, piston-ring–cylinder friction-pair sealing characteristics, heat-transfer optimization, and powertrain environmental adaptability. His work also extends to instrument development and platform construction for high-altitude and cold-start experimental systems. With strong skills in English technical writing, data analysis, calibration, and simulation, along with hands-on experience supervising graduate students and producing comprehensive technical documentation, he demonstrates excellent potential for independent academic research and interdisciplinary collaboration. This solid combination of scholarly output, technical depth, and project leadership supports his aspiration for a competitive research-faculty position.
