摘　　要：针对摩托车发动机结构紧凑、转速高的特点,在保证配气机构动力特性的基础上,对进气凸轮进行了改进设计;并在结构允许的前提下,对发动机进气系统也进行了相应的改进设计,使发动机的进气性能得到明显改善。试验表明,发动机扭矩最大提高9.5%,最大功率提高5.4%,发动机的燃油耗也有一定程度的改善。Aiming at motorcycle engineg characteristics of compact structure and high rotate speed, this paper improves the inlet cam on the basis of guaranteeing the power performance of valve train. The paper also carries out corresponding improvement of engine value system on the premise of structure allowance, which evidently improves the engine＇s inlet performance. Test indicates that engine＇s maximum torque and maximum power are enhanced respectively by 9.5% and 5.4%. Its fuel consumption is also improved in a certain extent.
