  • Patent number: 10358958
    Abstract: An exhaust gas heat exchanger including connection points for the exhaust gas flow, for connecting the exhaust gas heat exchanger to an exhaust gas supply line for supplying a hot exhaust gas and an exhaust gas withdrawal line for withdrawing the exhaust gas flow cooled in the exhaust gas heat exchanger. The exhaust gas flow flows through the exhaust gas heat exchanger in a bundle of exhaust gas guiding pipes in a flow direction. The exhaust gas heat exchanger is provided with at least one coolant supply connection and at least one coolant withdrawal connection. Coolant is guided in a coolant channel in the exhaust gas heat exchanger, inside which it flows around the bundle of exhaust gas guiding pipes. The coolant channel includes at least two regions which differ in terms of the flow direction of the exhaust gas flow by divergent flow directions of the coolant.

  • Patent number: 9371780
    Abstract: A four-stroke internal combustion engine having an engine brake, at least one exhaust valve per cylinder, each valve actuated by a camshaft and at least one first valve lever arrangement, and a device which advances the exhaust control, with the valve lever arrangement having an exhaust lever actuated by an exhaust cam and a brake lever actuated by a brake cam. The brake lever has a first brake lever part on the side of the camshaft and a second brake lever part on the side of the exhaust valve, with the two brake lever parts being rotatably mounted independent of each other about a lever axis and being rotationally connectable with each other in engine braking operation by a locking element which is adjustable between two positions.

  • Patent number: 8365813
    Abstract: A switchable exhaust gas heat exchanger includes an exhaust gas feed line and an exhaust gas discharge for an exhaust gas stream; a first exhaust gas passage and a second exhaust gas passage; a switching valve configured to switch the exhaust gas stream between the first and second exhaust gas passages; and a heat exchanger through which a coolant flows which is arranged in the first exhaust gas passage. The second exhaust gas passage routes the exhaust gas stream past the heat exchanger to the exhaust gas discharge. The switching valve is configured to be switched as a function of the temperature of the coolant and is a proportional control valve. A switching threshold and a switching limit of the coolant determine flow of the exhaust gas stream through the first and second exhaust gas passages.

  • Publication number: 20080202724
    Abstract: The invention relates to exhaust gas heat exchangers, as they are generally known, and to a sealing device which is especially suitable for using in exhaust gas heat exchangers. The inventive exhaust gas heat exchanger comprises connection points for the exhaust gas flow, for connecting the exhaust gas heat exchanger both to an exhaust gas supply line for supplying a hot exhaust gas and an exhaust gas withdrawal line for withdrawing the exhaust gas flow cooled in the exhaust gas heat exchanger. The exhaust gas flow flows through the exhaust gas heat exchanger in a bundle of exhaust gas guiding pipes in a flow direction. A coolant also flows through the exhaust gas heat exchanger, in a coolant flow. To this end, the exhaust gas heat exchanger is provided with at least one coolant supply connection and at least one coolant withdrawal connection. The coolant is guided in a coolant channel in the exhaust gas heat exchanger, inside which it flows around the bundle of exhaust gas guiding pipes.

  • Patent number: 4949075
    Abstract: A portable optical alarm system for area protection containing at least one light-emitting transmitter and a receiver sensing the emitted light is disclosed. The transmitters and receivers of the system form a chain in such a manner that the receiver sensing the light-impulses of the first transmitter is always connected electrically to the following transmitter and the last receiver of the system is connected electrically to the intervening organ and partly to the first transmitter of the system, or the first transmitter of the system is formed as a free-running unit. Transmitters and receivers can be arranged in an optical mutual arrangement where they are arranged in a casing containing the transmitter circuit and the associated battery along with the receiver circuit and the battery belonging thereto.
