Abstract
A valve with an opening is driven by an electric motor to rotate around the cylinder of an opposed piston engine such that the opening separately matches an intake and exhaust opening on the cylinder to allow fuel to enter the combustion chamber of the engine and allow exhaust to be expelled. The intake and exhaust cylinder openings may be separated from each other by approximately sixty degrees of the outside of the cylinder.
Claims10
An opposed piston engine comprising:
- a rotatable collar slidably positioned coaxially and centrally around a fixed cylinder, wherein the collar is configured at a position between a portion of the fixed cylinder and a portion of a fixed sealing bearing, the collar comprising an opening for receiving intake fuel as the opening rotatably aligns with an intake opening in the cylinder and an intake opening in the bearing and for expelling exhaust from the cylinder as the opening separately, rotatably aligns with an exhaust opening in the cylinder and exhaust opening in the bearing as the engine cycles through its respective combustion cycle.
The engine as in claim 3 wherein the ceramic comprises silicon carbide.
