    摘要： A combustion chamber assembly of a gas turbine, for combusting a fuel in the presence of combustion air, includes: a combustion chamber, in which combustion of fuel occurs; a precombustion chamber upstream of the combustion chamber; an atomization device that feeds a liquid fuel to the precombustion chamber; and a swirl body that feeds combustion air and gaseous fuel to the precombustion chamber. The combustion chamber assembly is configured as a dual-fuel combustion chamber assembly, which, in a gas fuel operating mode, feeds a mixture of a gaseous fuel and combustion air to the combustion chamber via the swirl body, and which, in a liquid fuel operating mode, feeds liquid fuel to the combustion chamber via the atomization device and combustion air to the combustion chamber via the swirl body. The atomization device includes an atomization lance with a central atomization nozzle, and plural decentralized atomization nozzles.

    摘要： A method for operating a ship propulsion system. A setpoint rotational speed is determined for a propeller shaft and a setpoint pitch angle for an adjustable propeller on a control side based on an adjustable propeller characteristic diagram and an operator. An engine is determined based on a ship's engine characteristic diagram and the setpoint rotational speed for the propeller shaft. An actual engine operating point is determined as a function of a measured actual rotational speed and a measured actual torque, so that when the drive power is constant, the set-point rotational speed for the propeller shaft and the pitch angle for the adjustable propeller can be varied while reducing fuel consumption of the ship's engine and, when this is possible, the setpoint rotational speed for the propeller shaft, the setpoint pitch angle for the adjustable propeller and the setpoint operating point of the ship's engine are adapted.

    摘要： A valve body for a gas exchange valve of a cylinder of an internal combustion engine can be brought to lie against a valve seat of the gas exchange valve for closing the gas exchange valve and can be removed from the valve seat to open the gas exchange valve. The valve body is formed in multiple parts and has a first valve disc part interacting with the valve seat and a second valve disc part that is connected to the first valve disc part in a fixed manner and faces a combustion chamber of the cylinder. Between the first valve disc part and the second valve disc part a hollow space serving at least for the cooling of the second valve disc part is formed.

    摘要： An internal combustion engine, includes at least one cylinder, wherein the or each cylinder includes a main combustion chamber for burning fuel in the cylinder, wherein an assembly serving to supply and/or ignite fuel is installed on a cylinder head of each cylinder between gas exhaust valves of the cylinder in such a way that the assembly is inserted into a cut-out in the cylinder head of the cylinder and is sealed to said cut-out, wherein a segment of the assembly that is inserted into the cut-out in the cylinder head of the cylinder has an oval contour in the cross-section, and wherein a bounding surface of said segment of the assembly, which bounding surface lies in the sealing region, is contoured in such a way that said bounding surface is continuously convexly curved outward in the peripheral direction.
