초록 ▼

An internal combustion engine includes in one aspect a source of a pressurized working medium and an expander. The expander has a housing and a piston, movably mounted within and with respect to the housing, to perform one of rotation and reciprocation, each complete rotation or reciprocation defining at least a part of a cycle of the engine. The expander also includes a septum, mounted within the housing and movable with respect to the housing and the piston so as to define in conjunction therewith, over first and second angular ranges of the cycle, a working chamber that is isolated from an intake port and an exhaust port. Combustion occurs at least over the first angular range of the cycle to provide heat to the working medium and so as to increase its pressure. The working chamber over a second angular range of the cycle expands in volume while the piston receives, from the working medium as a result of its increased pressure, a force relative to the housing that causes motion of the piston relative to the housing.

1. A rotary engine comprising: a housing comprising a wall that defines an internal cavity;a rotor rotatably disposed in the cavity, the rotor comprising a blade movably disposed within the cavity;a channel in the blade disposed to provide liquid between the rotor and the wall, the blade further comprising a serrated radial surface, the serrated radial surface configured to form barriers for flow of the liquid within a gap formed between the blade and the housing; anda seal between the blade and the wall, the seal comprising liquid from the channel. 2. The rotary engine of claim 1, wherein the liquid is water. 3. The rotary engine of claim 1, wherein the liquid is diesel fuel. 4. The rotary engine of claim 1, wherein the blade is pivotably coupled to the rotor. 5. The rotary engine of claim 1, wherein the blade is slidably coupled to the rotor. 6. A rotary engine comprising: a housing comprising a wall that defines an internal cavity;a rotor rotatably disposed in the cavity, the rotor having a radial face comprising a serrated surface disposed facing the housing wall;a channel in the rotor disposed to provide liquid between the rotor and the wall; anda seal between the rotor and the wall, the seal comprising the liquid from the channel, wherein the serrated surface is configured to form barriers for flow of the liquid within a gap formed between the rotor and the housing. 7. A rotary engine comprising: a housing comprising a wall that defines an internal cavity;a rotor rotatably disposed in the cavity;a roller disposed between the rotor and the wall, wherein the roller travels with the rotor; anda channel disposed so as to provide liquid between the roller and the wall, the liquid and the roller forming a seal between the rotor and the wall. 8. The rotary engine of claim 7, wherein the liquid is water. 9. The rotary engine of claim 7, wherein the liquid is diesel fuel. 10. The rotary engine of claim 6, wherein the liquid is water. 11. The rotary engine of claim 6, wherein the liquid is diesel fuel.
