| 20100199837 | VARIABLE LENGTH BENT-AXIS PUMP/MOTOR - In a bent axis hydraulic machine, a back plate and cylinder barrel vary in distance from a drive plate as a stroke angle of the cylinder barrel changes, thereby minimizing unswept fluid volume in the cylinders of the barrel at any stroke angle. Distance is controlled by one or more rollers, engaging respective tracks that define a profile of contact that determines the distance as a function of the stroke angle. Telescoping fluid supply channels are employed to maintain a fluid supply to the cylinder barrel as the distance changes. | 08-12-2010 |
| 20100077746 | Efficiency turbocharged engine system with bottoming cycle, and method of operation - A turbocharged engine system is configured to vaporize methanol using heat from exhaust gases and uses the vaporized methanol to drive the engine's turbocharger. The methanol may also be dissociated into hydrogen and carbon monoxide. After passing through the turbocharger, the vapor is injected into the engine by port injection. By selective timing of exhaust valves, the exhaust gases are separated into two streams, a first stream comprising gases ejected during exhaust blowdown, and a second stream of gases ejected during the remainder of the engine's exhaust stroke. The blowdown gases are employed to drive a separate turbine of the turbocharger. | 04-01-2010 |
