AI Thread Summary
Wankel engines are lubricated through a pressurized oil system, which is essential for sealing the rotating triangular piston. The lubrication method does not involve mixing oil with the fuel like a two-stroke engine; instead, it relies on a dedicated oil supply. The choice between wet and dry sump systems depends on the type of racing, with wet sumps being more cost-effective for drag racing and dry sumps preferred for oval or road racing. There is no widely recognized two-cycle Wankel engine design, although the discussion acknowledges that such engines may exist. Understanding the pressurized system involves oil being introduced at the top and collected at the bottom while maintaining the vertical orientation of the epitrochoid's major axis.

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?
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
