介绍了发动机与液力变矩器共同工作过程和匹配软件的组成模块。通过应用匹配软件,得到发动机和液力变矩器共同工作输入特性、共同工作输出特性和牵引特性曲线,从而判断二者匹配是否合理,对液力变矩器的选型具有重要的意义。 Introduced the engine and torque converter work together and match the composition of the software module. Through the application of matching software, the input and output characteristics of the engine and the torque converter, the common work output characteristic and the traction characteristic curve are obtained to determine whether the match between the two is reasonable and of great significance to the selection of the torque converter.
