Mazda Technical Brochure
This PDF from Mazda has several interesting technical points. Specifically the information about the intake runners and intake valving does a lot to explain how Mazda was able to get a very broad power curve from the engine. An excerpt regarding the dynamic intake: The sequential dynamic air intake system (S-DAIS) operates in response to engine speed by controlling the secondary and auxiliary ports, and opening/closing the variable intake valve installed upstream of the secondary port’s shutter valve. In this way, the system achieves optimal control of intake pressure propagation for each port. RENESIS also takes full advantage of the twin rotor’s charging effect to boost intake for more substantial low-to-mid range torque as well as increased torque and power output at higher engine speeds. Since all valves are formed to streamline flow through the intake passage during valve opening/closing, intake resistance is substantially reduced. |

Star Mazda Technical PDF Notes
This is an older document, but has some very interesting bits of technical information about our engine in a race environment, and some of the recommendations differ noticeably from the owner's manuals. Specifically, page 7 is interesting regarding EGTs. |

Mazda Distributed Renesis Fundamentals
This is a Mazda technical document that was distributed to the dealers for a basic fundamental understanding of the rotary engine and gets quite detailed about the function of every engine component, and how everything works together. A bit large (6.6mb), but a very good read if you want to understand more of the internals of the engine. This is specific to the Series1 (2004-2008) RX-8, and does not cover the many changes for the Series2 |
