摘　　要：根据实测示功图提出了利用气门落座冲击引起的干扰信号间接地确定气门关闭相位，并根据配气凸轮型线的对称性，确定内燃机动态配气相位的办法．研究了实际运转内燃机配气相位随负荷、转速的变化关系及原因．A method is developed to determine the valve closing phases by the valve impulse signal from the measured indicator diagram ,and the opening phases by the symmetry of the cam profiles. The variations of valve phases with loads and rotation speed are studied and their reasons are also analyzed.
