Abstract: In one embodiment, a combustion system for an engine is disclosed. The system includes a cylinder block that defines a cylinder bore and opposing pre-chambers located along a circumference of the cylinder bore. The system also includes a fuel injector located equidistant from the circumference of the cylinder bore that injects fuel in a direction perpendicular to a diameter of the cylinder bore. The system further includes a piston located within the cylinder bore that has a substantially conically shaped crown having fuel direction grooves that direct the fuel from the fuel injector towards the opposing pre-chambers.

The system also includes a fuel injector located equidistant from the circumference of the cylinder bore that injects fuel in a direction perpendicular to a diameter of the cylinder bore. The system further includes spark plugs located within the pre-chambers that ignite at least a portion of the fuel from the fuel injector to direct ignition flames into the cylinder bore.

Abstract: In one embodiment, an exhaust gas recirculation (EGR) system for an engine is disclosed. The EGR system includes an EGR cooler that cools recirculated engine exhaust gas and is mounted between a valve cover and valve train of a cylinder head in the engine.

Abstract: According to the disclosed embodiments, a thermoelectric generator (TEG) insert is used for recovery of engine waste heat. The embodiments include an engine having an exhaust manifold outlet, and an exhaust pipe having an inlet and an outlet. The TEG insert, which is configured to convert heat from exhaust gas leaving the engine into electrical power, may be disposed between the exhaust manifold outlet of the engine and the inlet of the exhaust pipe. The location of the TEG insert may maximize the thermal conversion of heat to electricity. Further, the size of the TEG insert may be minimized through the use of a high-efficiency nano-material. As a result, overall fuel economy may be maximized, the size of ancillary components, e.g., alternator, coolant pump, oil pump, etc., may be reduced, and minimal engine design change may be required to accommodate the TEG insert described herein.

Abstract: 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.

Abstract: 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.

Abstract: Featured is a rollerized camshaft support to rotatably support a camshaft of a Type I valvetrain, the camshaft having at least one rotating surface. Such a rollerized camshaft support includes at least one rollerized bearing and at least one bearing support for each of the rollerized bearings, where each bearing support includes a bearing upper support element and bearing lower support element. Each rollerized bearing includes an inner raceway; an outer raceway and a plurality of rolling elements disposed between the inner and outer raceways and extending widthwise across the raceways. The bearing upper support element and bearing lower support element are configured so as to receive there between a rollerized bearing. Also, the bearing lower support element is configured and arranged so to complement a portion of a configuration of the Type I valve train.

Abstract: A vehicle engine with integrated intake valve and fuel injector is provided. An 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.
