Discussion Overview
The discussion revolves around the lubrication methods used in Wankel engines, exploring both the types of lubricants and the mechanisms of lubrication. Participants also touch upon developments in lubricating closed-off engines.
Discussion Character
- Technical explanation, Debate/contested
Main Points Raised
- One participant mentions using 5w20 oil in an RX8, suggesting a specific lubricant type.
- Another participant questions whether the lubrication method is similar to a two-stroke engine, where oil is mixed with the fuel charge, or if there are alternative systems like wet/dry sump systems.
- A participant with experience from the 1970s describes the Wankel engine as having a pressurized oil system, emphasizing the importance of sealing the rotating triangle "piston." They also discuss the suitability of wet versus dry sump systems depending on the type of racing.
- One participant expresses uncertainty about the existence of two-cycle Wankel engines and seeks clarification on how the pressurized oil system operates, particularly regarding oil introduction and collection in relation to the engine's geometry.
Areas of Agreement / Disagreement
Participants express differing views on the lubrication methods and systems used in Wankel engines, with no consensus reached on the specifics of the pressurized oil system or the existence of two-cycle Wankel engines.
Contextual Notes
Participants reference various lubrication systems and their applications in racing contexts, but details on the mechanics of the pressurized system and its operational specifics remain unclear.
