| Number | Title | Issue Date |
| 7219647 | Force transfer mechanism for an engine A multiple watt-linkage force transfer mechanism is provided for an internal-combustion engine. The force transfer mechanism comprises two “bell cranks” that are used to drive a single crankshaft through a watt linkage mechanism. Each bell crank, in turn, is dri... | 05/22/2007 |
| 7188598 | Rotary mechanical field assembly An engine having a rotary member and a linear member includes a first axis about which the rotary member rotates and a second axis coupling the rotary member to an offset rotary element. The linear member is coupled to the offset rotary element by a first coupling f... | 03/13/2007 |
| 6904888 | Reciprocating piston device A reciprocating piston engine (or motor) includes plural reciprocating pistons operatively connected to a single intermediate oscillating shaft, and a crankshaft having a single crank pin operatively connected to the oscillating shaft, so that the crankshaft experie... | 06/14/2005 |
| 6230671 | Variable compression and asymmetrical stroke internal combustion engine A variable compression and asymmetrical stroke internal combustion engine includes a cylinder, a drive piston reciprocally disposed in the cylinder, an auxiliary piston reciprocally disposed in the cylinder, apparatus for reciprocating the auxiliary pisto... | 05/15/2001 |
| 5884590 | Two-stroke engine An oscillating lever arm engine includes rigidly connected opposing pistons moved by a single lever connected to a rotating crankshaft. When applied to a two-cycle internal combustion engine, one piston may function as a pump piston and the second piston ... | 03/23/1999 |
