To enhance the comprehensive performance and development efficiency of motorcycle engines, Jiangmen Dachangjiang Group Co., Ltd. introduced the VECTIS 3D CFD simulation platform and systematically conducted refined numerical simulation research on key flow and combustion processes within the engine. Leveraging the multi-physics field coupling capability of VECTIS, the study simultaneously evaluated the interaction mechanisms between in-cylinder flow and heat transfer, providing a basis for the co-design of the cooling water jacket and combustion chamber. The application of this technology shortened the calibration cycle for the motorcycle engines and successfully supported the development of a new-generation, low-emission, high-performance engine platform, significantly enhancing product competitiveness.
