Abstract: A measuring device for measuring a physical property of a fluid, including a base body which is closed along a peripheral line. The base body surrounds a first recess passing through the base body in the axial direction and the base body includes at least one second recess passing through the base body in the axial direction recess. At least one sensor device, which can be associated with the base body, can be bought into contact with the first recess.

Abstract: An insert that can be positioned in a gap between a first front face of a cylinder liner, the first front face facing a cylinder head, and a second front face of the cylinder head, the second front face facing the cylinder liner. The insert includes at least one compressible material.

Abstract: A method for operating a quantity-controlled internal combustion engine having at least two cylinders, including the following steps: ascertaining a present operating state; determining a number of cylinders or cylinder groups to be deactivated in dependence on the present operating state; deactivating or keeping deactivated a fuel supply for at least one cylinder to be deactivated or at least one cylinder group if at least one cylinder or at least one cylinder group is to be deactivated; and opening a flow-influencing element associated with the at least one cylinder or the at least one cylinder group for a fresh mass supply to the at least one cylinder to be deactivated or the at least one cylinder group to be deactivated.

Abstract: The invention relates to a method for regulating a gas engine (1) having a generator (5), wherein a regulator torque is calculated by means of a speed regulator from a speed regulator deviation, wherein a target volume flow is calculated at least as a function of the regulator torque, wherein a fuel volume is determined as a proportion of a fuel-air mixture as a function of the target volume flow, and wherein a target receiver pipe pressure is also calculated as a function of the target volume flow as a guide parameter for a receiver pipe pressure regulating circuit for regulating the mixture pressure (pRRA, pRRB) of a fuel-air mixture in the receiver pipe (12, 13) above the inlet valves of the gas engine (1). The invention is characterized in that a deviation of the regulator torque from a generator torque is calculated and the target receiver pipe pressure is corrected using the deviation.

Abstract: The invention relates to a method for regulating a stationary gas motor (1). In said method, a deviation of the regulated speed is calculated from a desired speed and an actual speed, a desired moment is determined as an adjustable variable from the deviation of the regulated speed by means of a speed governor, said desired moment being limited to an air ratio-limiting moment by limiting the moment, and a desired volume flow (VSL) is determined from the limited desired moment in order to define an angle (DKW1, DKW2) of the mixture throttle valve and an angle of the gas throttle valve.

Abstract: The invention proposes a method for controlling a stationary gas motor (1), wherein a rotational speed control deviation is calculated from a target rotational speed (nSL) and a current rotational speed (nIST), a target torque is determined from the rotational speed control deviation as the controlled variable, wherein a mixture throttle angle (DKW1, DKW2) is determined for the determination of a mixture volume flow and of a current mixture pressure (p1 (IST), p2(IST)) in a receiver pipe (12, 13) upstream of the intake valves of the gas motor (1) as a function of the target volume flow, and wherein a gas throttle angle is determined for determining a gas volume flow as the gas content in a gas/air mixture, also as a function of the target volume flow.
