Reform Practice of CDIO Teaching Mode Based on the Digital Engine Structure Principle

With the continuous advancement of computer and information technology, education and teaching methods have undergone profound changes. Addressing the challenges in the Engine Structure Principle course—such as its highly practical nature, complex principles, and difficulty in student comprehension—a simulation program for the engine oil supply regulation system was developed using digital technology. This paper analyzes key factors affecting engine fuel supply, including tank pressure, engine inlet total temperature, and fuel viscosity. By encouraging inquiry-based learning, the approach enhances students’ understanding of theoretical knowledge, improves teaching efficiency, and yields positive learning outcomes. Additionally, the CDIO (Conceiving-Designing-Implementing-Operating) teaching framework is integrated into the course, strengthening students’ ability to apply knowledge comprehensively and collaborate effectively in teams.
