Andreas Obieglo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Internal combustion engine and heat engine with multiple heat exchangers
    Patent number: 8931545
    Abstract: A heat exchanger arrangement is provided for an internal-combustion engine having a heat engine, which converts hot steam of a working medium by way of an expansion device to kinetic energy. The working medium, that can be delivered by a pump, can be heated in a first heat exchanger by a coolant and in a second heat exchanger by an exhaust gas of the internal-combustion engine. In the delivery direction, the working medium first flows through the first heat exchanger and, subsequently, through the second heat exchanger. The exhaust gas can flow through the first heat exchanger.

  • Vehicle suspension including a link
    Patent number: 8360452
    Abstract: A link of a vehicle suspension is elastic and includes three suspension points. A first point is adapted to be pivotally connected to a wheel carrier of the corresponding vehicle. A second point is adapted to be pivotally connected to a rigid chassis of the corresponding vehicle. The third point is adapted to be pivotally connected to a shackle, the shackle pivotally connecting the third point to the rigid chassis of the vehicle.

  • Heat Exchanger Arrangement
    Publication number: 20090229786
    Abstract: A heat exchanger arrangement is provided for an internal-combustion engine having a heat engine, which converts hot steam of a working medium by way of an expansion device to kinetic energy. The working medium, that can be delivered by a pump, can be heated in a first heat exchanger by a coolant and in a second heat exchanger by an exhaust gas of the internal-combustion engine. In the delivery direction, the working medium first flows through the first heat exchanger and, subsequently, through the second heat exchanger. The exhaust gas can flow through the first heat exchanger. A very high efficiency can be achieved for the internal-combustion engine with the above-described heat engine.

  • Thermodynamic engine
    Patent number: 7520133
    Abstract: A thermodynamic engine converts the superheated steam of at least one working medium into kinetic energy using a decompression device. Said engine includes a low-temperature circuit, in which a first working medium is transported through a first heat exchanger and subsequently through the decompression device and a high-temperature circuit, in which a second working medium is transported through a second heat exchanger and subsequently through the decompression device. The first heat exchanger and the second heat exchanger are located in the exhaust system of an internal combustion engine, and the internal combustion engine a coolant circuit can be used to heat the working mediums in separate collection containers.
