Design and Application of an Automotive Engine Performance Virtual Simulation Software

Abstract

"engine performance characteristics" constitutes the core teaching content of the course Engine Principles. Traditional teaching models typically separate theoretical instruction from practical training: theoretical teaching appears abstract due to the lack of dynamic demonstration tools, while experimental teaching is constrained by factors such as the number of equipment sets, space limitations, and safety risks, making it difficult to achieve hands-on operation for every student. Against this backdrop, this paper designs a lightweight virtual simulation teaching software for engine performance characteristics. Focusing on core experimental projects including speed characteristics, load characteristics, and universal characteristics, the software enables students to intuitively and safely explore the dynamic laws governing how engine performance parameters change with operating conditions through parametric modeling and interactive operations. The deep integration of this virtual simulation platform into theoretical classrooms has effectively addressed the challenge of "disconnection between theory and practice.This provides a feasible approach and empirical support for enhancing the effectiveness of theoretical teaching in the vehicle engineering discipline and for the reform of similar courses.
