Abstract

本实用新型公开了一种摩托车单缸发动机凸轮,所述凸轮是进气和排气共用的,通过改变凸轮的型线,提高凸轮两腰的升程值,加大凸轮两腰的缓冲,从而降低了油耗,提高了发动机的最大输出功率,比原机型增加0.4KW/h,并且发动机的排放优于原机型。

Description

摩托车单缸发动机凸轮
技术领域
本实用新型涉及一种凸轮,尤其是摩托车单缸发动机进排气所用的配气凸轮。
背景技术
目前,摩托车发动机进排气所用配气凸轮的型线关系到凸轮的丰满系数和充气性能,直接影响发动机输出功率、发动机输出扭矩、油耗和燃烧噪音等,直接决定燃油是否燃烧充分、尾气排放中有害气体的成分及浓度等。在能源价格飞涨的今天,消费者对摩托车性能要求苛刻的今天,各厂商均致力于研究发动机输出功率更高、油耗更低的摩托车发动机凸轮型线。
实用新型内容
本实用新型所要解决的技术问题在于提供一种最大输出功率高的摩托车单缸发动机凸轮。
本实用新型的技术方案如下:一种摩托车单缸发动机凸轮,所述凸轮(1)是进气和排气共用的,其旋转一周升程如下表:
