| 20120032441 | CRANK-WEB MOUNTED LINEARLY SEGMENTED STARTER GENERATOR SYSTEM - Featured is a starter/generator to start a reciprocating engine or generate electrical energy using the engine. The starter/generator includes a plurality of magnetic elements that establish a magnetic flux, each magnetic element being attached to a surface of the crankshaft so the element moves in a prescribed path as the crankshaft rotates; a plurality of stator elements being arranged within the engine so as to be maintained in fixed relation to a corresponding magnetic element as it moves in the prescribed path, and control circuitry being configured and arranged to control the functionality of each stator element. In one mode a stator element is controlled so that movement of the magnetic element by the stator element cause electrical energy to be generated in the respective stator element and so in another mode each stator element/magnetic element combination operates the motor/generator as a motor. | 02-09-2012 |
| 20120031367 | CYLINDER BORE WALL OIL SQUIRTER, RECIPROCATING ENGINE EMBODYING SAME AND WHERE THE ENGINE FURTHER EMBODIES A ROLLERIZED CRANKTRAIN - Featured is a cylinder wall oil delivery system for a reciprocating engine having at least one cylinder and at least one piston movably received in the cylinder as well as a reciprocating engine embodying such a cylinder wall oil delivery system. Such an oil delivery system includes a squirter that is fixably arranged in each cylinder so that oil is directed therefrom to two different areas of the cylinder wall. The squirter includes a first nozzle being orientated so the oil is directed to one of the two cylinder wall areas and a second nozzle being orientated so the oil is directed to the other of two cylinder wall areas. In particular embodiments, the squirter is arranged so the oil targets the piston skirt thrust and anti-thrust travel areas of the cylinder wall and so as to regulate the oil flow from each nozzle. | 02-09-2012 |
| 20120031366 | ROLLERIZED CRANKTRAIN BEDPLATE, RECIPROCATING ENGINE EMBODYING SAME AND ENGINE FURTHER INCLUDING ROLLERIZED CRANKTRAIN - Featured is a bedplate for a reciprocating engine having a rollerized cranktrain. Such a bedplate includes a peripheral support structure having sides and ends, a plurality of cross members that extend between the sides of the peripheral support structure, and a plurality of rolling element bearings. Each of the plurality of cross members includes a bearing support portion, the bearing support portion being configured so as to receive and retain therein a portion of one of the rolling element bearings. Also, the portion of the rolling element bearing is such that when the bedplate is secured to a cylinder block of the reciprocating engine, the bearing support portion rotatably supports a crankshaft of the reciprocating engine. Also featured is a reciprocating engine having such a bedplate. | 02-09-2012 |
| 20110120421 | Variable compression ratio system for internal combustion engines and method of varying compression ratio - A system for adjusting a compression ratio of an internal combustion engine, includes a piston position adjusting mechanism having a lever pivotably mounted on each of the connecting rods, adapted and configured to pivot when actuated, a cam, rotatably mounted with respect to each of one or more pistons and respective connecting rods, adapted and configured to maintain, at any moment, one of a plurality of spacings therebetween, rotation of the cam by a preselected angle causing a change in relative spacing between the head of the respective piston and small end of the connecting rod. The trigger is adapted and configured to cause pivoting of the lever, engagement between the cam and the lever, and rotation of the cam by the preselected angle. | 05-26-2011 |
| 20110120396 | INTEGRATED COOLANT FLOW CONTROL AND HEAT EXCHANGER DEVICE - A coolant flow control system ( | 05-26-2011 |
| 20100229826 | Integrated intake valve and fuel injector for vehicle engine - intake valve is housed in an intake valve body which is provided with a valve seat face. A fuel passage is positioned at the valve seat face toward a spark plug. Further, a valve stem is disposed at the intake valve at a position above the valve seat. The valve stem can be in fluid communication with an intake valve guide and a high pressure tube. With the integrated intake valve and fuel injector, e.g., high level of charge homogeneity can be achieved in a simple manner. | 09-16-2010 |
