====Considering two chambers==== Richard Franz Ansdale, [[Wolf-Dieter Bensinger]] and [[Felix Wankel]] based their analogy on the number of cumulative expansion strokes per shaft revolution. In a Wankel rotary engine, the eccentric shaft must make three full rotations (1080Β°) per combustion chamber to complete all four phases of a four-stroke engine. Since a Wankel rotary engine has three combustion chambers, all four phases of a four-stroke engine are completed within one full rotation of the eccentric shaft (360Β°), and one power pulse is produced at each revolution of the shaft.<ref name="Bensinger 1973 p. 65">{{cite book |last1=Bensinger |first1=Wolf-Dieter |title=Rotationskolben-Verbrennungsmotoren |place=Berlin, Heidelberg, New York |date=1973 |isbn=978-3-540-05886-1 |oclc=251737493 |language=de |page=65}}</ref><ref name="Okimoto 2002 pp. 810">{{cite journal |last1=Okimoto |first1=Haruo |title=Der Rotationskolbenmotor Renesis |journal=MTZ - Motortechnische Zeitschrift |publisher=Springer |volume=63 |issue=10 |year=2002 |issn=0024-8525 |doi=10.1007/bf03226650 |pages=810 |language=de}}<br/> {{cite journal |last1=Okimoto |first1=Haruo |title=The Renesis rotary engine |journal=MTZ Worldwide |publisher=Springer |volume=63 |issue=10 |year=2002 |issn=2192-9114 |doi=10.1007/bf03227573 |pages=8}}</ref> This is different from a four-stroke piston engine, which needs to make two full rotations per combustion chamber to complete all four phases of a four-stroke engine.
