  • Desmodromic valve designs for improved operation smoothness, stability and package space
    Patent number: 6505590
    Abstract: A desmodromic drive (30) for imparting reciprocal translation to a valve (32) has a cam ring (52) that rotates about an axis (42), a follower (50) that reciprocates with axial motion as the ring rotates, an endless cam track (69) on the ring, and rollers (76, 78) on the follower that ride along the cam track as the ring rotates. A follower guide (48) guides the follower for axial. Rollers (60, 62) constrain the follower against rotation on the follower guide.

  • Internal combustion engine with siamesed cylinder bores and pistons
    Patent number: 5927243
    Abstract: A reciprocating internal combustion engine includes a siamesed piston bore having a configuration formed by the intersection of two circular cylindrical elements and a matching piston having a similar siamesed configuration. This cylinder configuration allows a four cylinder engine to be about 25% shorter with the same displacement as an engine having circular cylinders and the same stroke.
