摘　　要：本文针对KTM690 LC4单缸发动机进行优化设计,旨在利用谐振进气技术以及可变进气混合技术对KTM 690 LC4发动机进行进气系统的开发设计并确认阀门介入转速点,以此提升其在中低转速下的扭矩,提高中高转速的功率,延长其扭矩平台,最终提升整车的动力性能。在进气系统的实体制造上探索使用不同材料进行快速成型制造,使最终制造出的进气系统在满足设计目标的同时具有足够的使用强度,具有足够长的使用寿命。In this paper,the optimized design of the KTM 690 LC4 single-cylinder engine is aimed at developing and designing the intake system of the KTM 690 LC4 engine by using the resonance intake technology and the variable intake mixing technology,and confirming the valve intervention speed point so as to improve the torque at low and medium speeds,increase the power at medium and high speeds,and prolong the torque platform,which ultimately improves the power performance of the whole vehicle.In the physical manufacturing of the intake system,we explore the use of different materials for rapid prototyping,so that the final intake system can meet the design objectives while having sufficient strength and long service life.
