| 20090277417 | Crankshaft-free drive shaft and piston assembly of a split-cycle four-stroke engine - A drive shaft and pistons assembly of a split-cycle four-stroke engine that contains a drive rotary shaft that supports at least two circular eccentrics pivotally connected to the first ends of connecting rods, the other ends of which are pivotally connected to the respective pistons. The circular eccentrics are angularly shifted with respect to each other by an angle optimal from the viewpoint of efficiency of the engine. The invention also provides a method consisting of removably securing the circular eccentrics of the aforementioned engine in different angular positions with respect to each other, testing the performance of the engine, removably mounting the circular eccentrics in a second and subsequently different angular positions with respect to each other, repeating the test of the engine, finding the angular positions of the circular eccentrics that provides the best performance of the split-cycle four-stroke engine, and creating a pre-production prototype of the split-cycle four-stroke engine based on the aforementioned finding. | 11-12-2009 |
| 20090301429 | Engine and Power Transmission Device - An engine according to an aspect of the present invention includes a crankshaft which is disposed in a substantially horizontal direction, first power transmission means, an input shaft, a first output shaft, second power transmission means, and a power transmission case. The input shaft is disposed below the crankshaft in parallel with the crankshaft, and the input shaft receives a power from the crankshaft through the first power transmission means. The first output shaft supplies the power from the input shaft, and the first output shaft is disposed perpendicular to the crankshaft. The second power transmission means transmits the power of the input shaft to the first output shaft. The power transmission case accommodates the input shaft, the first output shaft, and the second power transmission means therein. | 12-10-2009 |
| 20110017168 | WEIGHTED CENTRIFUGAL CLUTCH - A pressure washer system includes a combustion engine having a power takeoff. The center of the power takeoff defines an axis of rotation. The pressure washer system further includes a centrifugal clutch coupled to the power takeoff. The clutch comprises a flywheel having a center of mass positioned along the axis of rotation. The pressure washer system also includes a water pump coupled to the clutch output shaft. | 01-27-2011 |

| 20110220057 | CLUTCH ACTUATOR MOUNTING STRUCTURE FOR INTERNAL COMBUSTION ENGINE - A clutch actuator mounting structure for internal combustion engine has excellent maintainability such that clutch actuator maintenance and the like can be carried out without dismounting an engine case. The clutch actuator mounting structure for an internal combustion engine includes, in the engine case, a power transmission mechanism designed to transmit rotational power of a crankshaft to an output shaft through a shift clutch and a transmission. The engine case is formed with a clutch actuator containing part in which a clutch actuator for engaging/disengaging the shift clutch is contained. The clutch actuator containing part has a clutch actuator mounting/dismounting port through which to mount and dismount the clutch actuator. The clutch actuator mounting/dismounting port is formed to be exposed to the exterior. | 09-15-2011 |
| 20140283782 | APPARATUS FOR ROTATING A CRANKSHAFT - An apparatus for rotating a crankshaft is described. The crankshaft includes a main shaft and an axially offset crank pin with each end of the crank pin connected to the main shaft by a respective crank arm. The apparatus includes at least a first piston. A connecting frame is attached to the first piston, and the first piston is configured to alternately drive the connecting frame in reciprocating motion. A hub is rotatably mounted within the connecting frame with the hub defining a channel therein, and the crank pin is disposed within the channel. The apparatus also includes a locking mechanism that has a locked state in which the hub is prevented by the locking mechanism from rotating within the connecting frame and has an unlocked state in which the hub may freely rotate within the connecting frame. The reciprocating motion of the first piston and the connecting frame imparts reciprocating travel of the crank pin between a first end of the channel to a second end of the channel and consequent rotation of the main shaft when the locking mechanism is in the locked state; while the crankshaft and the hub rotate freely when the locking mechanism is in the unlocked state, and the first piston and the connecting frame are in a stationary position when the locking mechanism is in the unlocked state. In at least some example embodiments, the first piston may remain stationary at its top dead center and/or its bottom dead center while the crank pin travels within the channel and the main shaft consequently rotates, when the locking mechanism is in the locked state. | 09-25-2014 |
| 20140352653 | Power Delivery Devices for Reciprocating Engines and Related Systems and Methods - In some aspects, a power delivery device configured to couple to a reciprocating element of a reciprocating engine is configured to couple to a power output element via a substantially steady, invariant (e.g., constant) moment arm in order to generate increased torque and power. | 12-04-2014 |
