Heh all along I'm wondering, what kind of thermodynamic cycle is it? By six strokes, does it mean there are actually distinct new phases to the PV graphs compared to Atkinson/Carnot/Miller?
Or is it just masquerading a well-known cycle underneath six strokes, only some parts are being optimised?
- Ccecil 2y agoNot sure myself... Seems to be like it is a Miller cycle (or could be) on the initial 4 strokes. Which would allow you to control the timing of the "Compression max point" in the stroke by varying the boost. That may also vary the amount of spent fuel remaining for the second "scavenge" stroke...which if I am reading comments above correctly it pulls air from ports lower in the cylinder which would help clear the cylinder for the next 4 stroke cycle. Seems to me more focused on reburning/scavenging to make a "cleaner" burn than anything else though. *Not an engineer...just a shadetree mechanic who reads too deep into engine papers.
