关于柴油机与液力变矩器匹配的一些论文，很好的知识(Many designs of rotary engine were proposed in the past 100 years, including the recent rotary vane concept 10 , but only the gasoline Wankel engine has become a production success. This has good power-weight ratio, inherent balance, and smoothness, but suffers from reduced effi ciency, sealing, and emissions prob-lems, particularly of unburned hydrocarbons 1)
