Abstract: A fuel supply system of an engine designed as a gas engine or dual-fuel engine, has at least one solenoid valve. The solenoid valve is designed for introducing gas fuel into charge air or into a charge air line leading to at least one cylinder of the engine. The respective solenoid valve includes a valve body and an actuator with at least one magnetic plate and with at least one coil for actuating the valve body. The at least one solenoid valve of the solenoid valve is formed out of a corrosion-resistant material or is coated with a corrosion-resistant material.

Abstract: A spark plug with a center electrode having a first body and a second body of a precious metal, which is connected to the first body, an earth electrode arranged in the radial direction roundabout the center electrode, and an annular ignition gap formed between the center electrode and the earth electrode. The second body is formed as an annular element with a central recess. The first body has a main body and a projection, which extends into the recess of the second body. The second body is positively held on the first body via an undercut formed in the region of the projection of the first body between the first body and the second body.

Abstract: A method of operating a sensor system having at least one proximity sensor, with regard to generating a trigger signal indicative of an occurrence of an operator-intended event in the presence of noise. The method includes repetitive steps of: acquiring the sensor signal at specified sampling times, comparing a value obtained as a presently sampled sensor signal with a presently valid first threshold value, generating a trigger signal if the value obtained as the presently sampled sensor signal is as large as or exceeds the presently valid first threshold value, omitting to generate a trigger signal if the value obtained as the presently sampled sensor signal is less than or equal to the presently valid first threshold value, forming a subset out of the sampled sensor signals, determining an update value for the first threshold value, and replacing the presently valid first threshold value by the update value.

Abstract: 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.

Abstract: A data input device includes a first electrode structure having a first collector electrode and a first plurality of finger electrodes extending from the first collector electrode and a second electrode structure including a second collector electrode and a second plurality of finger electrodes extending from the second collector electrode, the first and second electrode structures being arranged on a first carrier layer in such a way, that in an active area of the data input device, the first plurality of finger electrodes extend between the second plurality in an interdigitating arrangement.
