 The wall-flow-guided and interferential interactions of the lateral swirl combustion system for improving the fuel/air mixing and combustion performance in DI diesel enginesYanlin Chen, Xiangrong Li, Xiaolun Li, Weihua Zhao and Fushui Liu Energy, 2019, vol. 166, issue C, 690-700 Abstract: The lateral swirl combustion system was designed based on and to improve upon the traditional ω-type combustion system. Previous research has verified the outstanding combustion performance of the lateral swirl combustion system. In this study, to reveal the interaction mechanisms between the lateral swirl combustion chamber and spray jets, experimental and numerical study was conducted at various spray incident angles (φ) where the relations between the combustion chamber and spray jets are different. The spray impinging processes and combustion performance were measured in a single-cylinder diesel engine with an endoscopic system. The distribution of velocity and the equivalence ratio was analyzed through simulation. Then, under the optimal φ, the fuel/air mixing quality and combustion performance was verified in comparison with a double swirl combustion system.
