Hallo everybody!: the attached chart, from a technical analysis of NSU Spider Wankel motor, indicating how much the SFC worsens under light load, plus one page in the SAE paper 790435, by T Kohno et al, from Toyota, indicates that the Volumetric Efficiency, MEP, increase from a Reed-Valve cage could be specially interesting under the average use of an automobile engine

I've prepared a list of papers I like, provided it may have interest for someone. It must be purchased directly al SAE or other publishers, there are links in the web for free download of the three versions of the Toyo Kogyo Kenichi Yamamoto books about Wankel engine, 1969, 1971 and 1981. Rotaryeng.net a site by Paul Lamar, devoted to Mazda transformed for experimental airplane use, has lots of documents
