摘要: An internal combustion engine includes a centrifuge, a centrifuge pump, and a controller. The centrifuge is configured to separate foreign particles from a lubricant, wherein the centrifuge is so designed that a lubricant volumetric flow directed into the centrifuge produces and/or maintains a rotational movement of the centrifuge. The centrifuge pump is configured to produce and/or increase the lubricant volumetric flow directed into the centrifuge. A controller is configured to provide control of the centrifuge pump according to a setpoint value for a kinematic operating parameter and/or for a setting parameter of the centrifuge pump. The controller is configured to gradually change the setpoint value for control of the centrifuge pump upon shutdown or starting of the centrifuge pump.

摘要: Internal combustion engine, preferably a gas engine, comprising a pre-chamber having a pre-chamber intake system and a main combustion chamber having a main combustion chamber intake system, wherein by use of the intake systems a predetermined amount of energy of fuel can be supplied to the main combustion chamber for a combustion, wherein a control unit is configured to control the intake systems according to the following operation modes:
a first operation mode, in which a majority of a fuel energy amount for the combustion in the main combustion chamber is supplied directly to the main combustion chamber by use of the main combustion chamber intake system, and
a second operation mode, in which a majority of the fuel energy amount for the combustion in the main combustion chamber is supplied via the pre-chamber to the main combustion chamber by use of the pre-chamber intake system.-

摘要: Spark plug for igniting a combustible fuel in an internal combustion engine, wherein the spark plug has an igniter arranged at an end of the spark plug facing the combustion chamber, when the spark plug is mounted in the internal combustion engine. The spark plug includes a wall and a sealing area. The wall at least partially surrounds the igniter. The sealing area is used for sealing the combustion chamber against the environment. The wall has the sealing area located at an end of the wall, which end faces the combustion chamber when the spark plug is mounted in the internal combustion engine.

摘要: A power system includes at least one generator driven by at least one of a number (N) of prime movers, at least one energy storage device, and at least one control device, wherein the generator and the energy storage device provide electrical energy to a power grid having an external load. The power system includes at least one first measuring device for determining at least one first signal for a computer to determine what amount of electrical power (ΣPG,i) has to be generated by the at least one generator to meet a power requirement (Pload) of the external load. The at least one control device is configured to receive the at least one first signal and to influence the control of the speed (ni) of the at least one of the number (N) of prime movers or the frequency (f) of the power grid taking into account the at least one signal to change the mechanical power generated by the at least one of the number (N) of prime movers such that the electrical power provided by the at least one generator approaches the power requirement (Pload) of the external load in situations where the power requirement (Pload) of the external load is at least partially provided for by the at least one energy storage device.
