  • Patent number: 4417560
    Abstract: An intake air booster for boosting air flow in an internal combustion engine or the like which includes a first air passageway communicating directly with an engine intake manifold having a plurality of interleaved rotating and stationary blades, the rotating blades forming a second internal passageway, the stationary blade providing an outer housing, so that air passing through this first passageway will be stirred by virtue of the interaction against these blades; the second air passageway formed by an internal band contained on the rotating blades includes caps on bottom and top portions of the passageway provided with a plurality of inlets and outlets and a source of compressed air adapted to engage the cap and by so doing providing additional air through the air passageway while simultaneously increasing the rotation of the rotary blades in the first air passageway, the source of compressed air including a reservoir and appropriate valving and sensing means which selectively engage the compressed air for

  • Patent number: 4407239
    Abstract: An internal combustion rotary engine in which only a single spark plug is utilized to ignite fuel/air mixture located within a single cylinder. Within the cylinder is located a pair of pistons mounted in a back-to-back relationship. A power output shaft is attached to the cylinder. The pistons connect with a connecting shaft assembly which extends through an access opening assembly formed within the cylinder. The cylinder is rotatably mounted within the fixed engine housing. The connecting shaft assembly connects with an auxiliary power output shaft. An appropriate fuel/air inlet port is provided within the fixed engine housing and there is also provided an exhaust port. Each piston incurs a power stroke for each single rotation of the cylinder.

  • Patent number: 4392352
    Abstract: A method and an apparatus are proposed for regulating and attaining an anti-overload means in turbochargers and in internal combustion engines equipped therewith, serving in cost-favorable embodiment both in Otto (gasoline) engines and in Diesel engines to limit the air throughput of the engine in accordance with the engine speed and to provide that neither the turbocharger, as a result of exceeding its limit rpm, nor the engine can be endangered if the engine exceeds the permissible compression and combustion pressure. In summary, the intent is to attain a favorable adjustment of the exhaust turbocharger over the entire rpm range of the internal combustion engine. To this end, the exhaust gas quantity delivered to the exhaust turbocharger is controlled in accordance with the throughput, that is, in accordance with the air quantity delivered to the engine, with the aid of a bypass line.

  • Patent number: 4373336
    Abstract: An internal combustion engine has a turbo-supercharger connected to an engine charge air intake manifold and an exhaust gas turbine connected to an engine exhaust manifold. An automatic bypass includes a bypass line interconnecting the exhaust manifold upstream of the exhaust gas turbine and the air intake manifold downstream of the compressor. A bypass valve in the bypass line comprising an adjustable throttle member for adapting the quantity of bypassed gas to the respective operating state of the engine. An actuating piston closes the throttle member in response to pressures from the compressor side above a pre-selected value. The actuating piston is disposed on a side of the throttle member facing away from the air intake manifold. The resistance of the valve to flow from the compressor side to the turbine side is less than the resistance in the opposite direction. The resistance to flow, and the fully unseated valve position define an operating curve of the engine which is adjustable.

  • Patent number: 4353331
    Abstract: An internal combustion engine utilizes a first outer oscillating piston connected to the engine housing by means of a pivot bearing and a second inner piston connected to the first piston by means of a pivot bearing connection. The inner piston is rotatably connected through an eccentric shaft to a main power shaft. Rotation of the eccentric shaft causes the inner piston to oscillate relative to the outer piston and also causes the outer piston to oscillate relative to the engine housing. Each of the oscillating pistons defines two opposed chambers of complementary and variable volumes; and fluid porting means, responsive to the motions of the pistons, are provided to control the flow of fluid among the chambers to attain a dual expansion of the combustion gases. The result is an internal combustion engine which is efficient, quiet, cool running and less subject to wear than presently used engines.

  • Patent number: 4353337
    Abstract: A rotary internal combustion engine having an elliptical wall member which forms an elliptical internal chamber. A drive shaft is rotatably mounted in the housing and extends transversely through the elliptical chamber. A substantially cylindrical rotor is secured to the drive shaft within the chamber and has a plurality of circumferentially equidistantly spaced vane members radially slidably disposed within the rotor. A source of fluid pressure communicates with the radially inner end of the vane members to urge the vane members radially outwardly so that the vane members contact the elliptical wall. Moreover, each vane member is of a sliding laminated construction to ensure a sealing engagement between the vane member and the wall surface. A fuel and air mixture is supplied to the rotor via an air suction chamber which thereafter is compressed with the fuel between the rotor, the wall portion and adjacent vane members.
