The results show in the region of high efficiency ratio for torqueconverter operation, power-split transmission efficiency is always better than that of torqueconvertertransmission.
在液力变矩器工作的高效率速比区域， 分流传动的效率始终优于液力变矩器传动；

Inside the transmission, an electric oil pump replaces the torque-converter pump.
同时在变速箱内用一部电子油泵取代了原有的变矩器泵。
