With the transition of China's energy structure towards green and low-carbon,energy and power courses in universities are also facing a new round of curriculum reform.Internal combustion engine emissions and control is an important elective course in the field of energy and power engineering.However,the research objects of the course are abstract and complex,and key systems and equipment are difficult for students to understand through traditional face-to-face teaching.Practice has proven that integrating numerical simulation technology into project-based teaching and reconstructing teaching content using SPOC's blended online and offline teaching mode can enable students to have a more comprehensive and in-depth understanding of theoretical knowledge.After the reform,students'engineering problem-solving ability and innovative thinking have been significantly improved,and their teamwork and expression abilities have also been exercised.
