- Maybe I've been in a rotary mindset too long and don't know enough about
- Piston Engines to boot, but:
-
- The bearings in the center of the rotor are lubricated and cooled by oil
- flowing through the eccentric shaft and then recovered by the shaft at a
- different point. There are circular oil seals around the bearing area that
- form a barrier against the flat housing. When the oil seals ( as well as the
- side seals--the seals that trace the edges of the triangle, three to a side
- ( not to be confused with the Apex seals on the tips of the rotor ) ) start
- to wear out, more and more oil will sneak past them and into the combustion
- chamber. This is a hallmark sign of a worn-out rotary.
-
- Does this tell you close to what you want to know? ;)
-
- As I'm really ignorant about pistons:
- How does the piston's movement in a piston engine prevent oil from
- burning in the combustion chamber?
