Abstract: An exhaust gas heat recovery system for an internal combustion engine has a pump for conveying an operating fluid, an evaporator for converting the operating fluid from the liquid state to the gaseous state, and a condenser for liquefaction of the operating fluid, and having an expansion engine through which the gaseous operating fluid can flow. A sensor is arranged on the expansion engine with which a function of the expansion engine can be monitored. An exhaust system may have such an exhaust gas heat recovery system, and a method for the diagnosis of such an exhaust heat recovery system.

Abstract: An internal combustion engine having at least one combustion chamber, the internal combustion engine being connected via the exhaust thereof with an exhaust system. Disposed in the exhaust system is a heat exchanger of an exhaust heat recovery system, which can be used to transfer the waste heat of the exhaust gas to an operating fluid of the exhaust heat recovery system. Furthermore, the internal combustion engine is couplable to an air-conditioning compressor of an air-conditioning circuit. The exhaust heat recovery system has a further heat exchanger, in which the waste heat of a compressed refrigerant of the air-conditioning circuit is transferred to the operating fluid of the exhaust heat recovery system.

Abstract: An axial piston motor having a cylinder housing, in which a plurality of cylinders are formed, and having pistons which are movably guided in the cylinders, wherein the pistons are attached to a swash plate and wherein a flow of a fluid that has entered via an inlet into the axial piston motor is controlled into and out of the cylinders by means of inlet and outlet valves, wherein the inlet and/or outlet valves comprise fluid change openings which are formed in a cylinder head plate and which can be temporarily released and covered by means of a rotary slide, for which purpose the rotary slide forms at least one passage opening.

Abstract: A drive unit for a motor vehicle that has a combustion machine having an internal combustion engine (10) as well as an exhaust gas system via which exhaust gas can be discharged from the internal combustion engine (10), and has a cyclic device that can be used to convert the thermal energy contained in the exhaust gas into mechanical work in a clockwise thermodynamic cycle, whereby the cycle comprises a heat transfer from the exhaust gas to a working medium in a first heat exchange device, as a result of which the temperature and/or the pressure of the working medium is increased, comprises an expansion of the working medium in an expansion device (30) for generating the mechanical work, and comprises a heat transfer from the working medium to a cooling medium in a second heat exchange device.

Abstract: A heat exchange device having a first media channel for a first medium and a second media channel for a second medium is further refined in that, in at least one section of the heat exchange device, a third media channel for a transfer medium is arranged between the first media channel and the second media channel, so that the heat transfer from the first medium to the second medium takes place via the transfer medium.

Abstract: A method of processing binary data for transmission from a first computing system to one or more other computing systems within a character-based data file is provided. The method comprises receiving, at the first computing system, a binary data string to be stored within the character-based data file. At least a portion of the binary data string represents data other than character data. The method further comprises encoding, using an encoding module of the first computing system the binary data string using a codepage-independent encoding scheme. The encoding module is implemented using instructions that are executable by one or more processors and stored in one or more computer-readable media. The method further comprises storing the encoded binary data string in one or more of a plurality of data segments of the character-based data file. The character-based data file is configured such that all data stored in the plurality of data segments is indicated as representing character data.
