How is a wankel engine lubricated?

[chhitiz]

i was admiring its animation like when this popped into my head.
any answers?
also anybody know any latest developments in lubricating closed off engines?

I believe when I had an RX8 it used 5w20

yeah, but that's just the type of lube
what is the actual method?
is it just mixed with the charge like a two stroke?
is there no other way, like having a wet/dry sump system?

i worked on a wankle engine in the 1970s...about like any other raace engine..has pressureized oil system but the trick is to seal up the little rotating triangle ' piston"

as far as wet sump dry sump...it depends on what type racing..if drag racing...wet sump is cheaper lighter ..if oval or road racing...you better have dry sump oil system..

i know of no two cycle wankel engines..not to say there are not any but I have not seen any..

i do not understand what u mean by that.
how does the pressurized system work? is the oil introduced at top and collected thru bottom while keeping the "major axis" of the epitrochoid vertical?
