使用 AVL BOOST 软件对某款增压汽油机的气门升程曲线进行优化,以提高发动机的低速扭矩.通过仿真计算和试验验证表明:保持排气门关闭角不变,推迟排气门开启角可以显著提高发动机的低速扭矩,而高速性能没有下降.
使用 AVL BOOST 軟件對某款增壓汽油機的氣門升程麯線進行優化,以提高髮動機的低速扭矩.通過倣真計算和試驗驗證錶明:保持排氣門關閉角不變,推遲排氣門開啟角可以顯著提高髮動機的低速扭矩,而高速性能沒有下降.

In order to improve the low speed torque of the TC gasoline engine , the valve lift curve was optimized by using AVL BOOST and verified . The results show that the low speed torque was improved obviously and high speed performance was not reduced by retarding the EVO with EVC remained .
