1.一種配氣凸輪，其凸輪型線工作段采用高次多項(xiàng)式動(dòng)力方程，其方程式為：

H＝H_max(1+c₂θ²s+c₄θ⁴+c_pθ^p+c_qθ^q+c_rθ^r+c_sθ^s)

其中：H為凸輪升程，Hmax為凸輪最大升程，

θ為凸輪角度，p.q.r.s為指數(shù)；

其特征是：上述方程中：

Hmax＝6.4～6.6mm

c₂＝-1.6～-1.8??c₄＝0.1～0.2

c_p＝9.0～13.0???c_q＝-10～-18??c_r＝5～15??c_s＝-0.8～-1.6

p＝12～18???????q＝15～20?????r＝22～35??s＝28～36

凸輪基圓直徑￠＝26.6mm；

總包角為170°～190°；工作段角度為120°～150°；

緩沖段角度θ1＝20～30°、θ2＝20～30°。

2.根據(jù)權(quán)利要求1所述的配氣凸輪，其特征是：所述凸輪角度與凸輪升程的對(duì)應(yīng)關(guān)系形成升程表，該升程表為：
