A method and a device for operating an internal combustion engine having an intake manifold and a ventilation system may allow a reliable and fault-free diagnosis of a fault in the ventilation. The ventilation system may be a tank ventilation or a crankcase ventilation. The ventilation duct is conducted to the intake manifold of the internal combustion engine. At least one pressure differential may be determined between an intake-manifold pressure or an ambient pressure, on the one hand, and a pressure in the ventilation duct, on the other hand. A fault in the ventilation may be diagnosed as a function of the at least one pressure differential.

A lubrication system is provided for delivering a lubricant to a plurality of nozzles. The lubrication system includes a reservoir for the lubricant; a pump fluidly coupled to the reservoir and configured to remove a flow of the lubricant from the reservoir; a lubrication sensor positioned between the pump and the plurality of nozzles and configured to detect a blockage in the plurality of nozzles and to generate a blockage signal when the blockage is detected; and an indicator coupled to the lubrication sensor and configured to generate a warning based on the blockage signal from the lubrication sensor.

The invention discloses an anti-leakage lubricating oil supply system of a power device, and belongs to the technical field of mechanical and power equipment lubrication supply. The lubricating oil supply system comprises an oil supply pump oil inlet pipe, an oil supply pump, an oil supply pressure meter, an oil supply pump oil outlet pipe, an oil supply filter, lubricating oil, an oil storage tank, an equipment oil return pipe, an oil storage tank pressure meter, a vacuum pump air inlet pipe, a vacuum pump air inlet filter, a vacuum pump and a vacuum pump exhaust pipe. According to the system, the lubricating system conducts lubrication in the running manner of the negative pressure lower than the environment pressure, an inlet and an outlet of a lubricating oil pump are in negative pressure; during work, the lubricating oil pump conveys the lubricating oil to the lubricating part; through control the pressure of the vacuum pump and the oil pump, it is guaranteed that the pressure atthe lubricating part is lower than the outer pressure of the lubricating system, a small amount of gas flows into a sealing cavity from the exterior of the lubricating system, the lubricating oil is driven to flow in the equipment oil return pipe direction, and accordingly the purpose that lubricating oil is prevented from leaking outwards from a gap is achieved. The system is applicable to gas turbines or other high-speed rotation power machines.

A lubrication system and wind turbine are provided having one or more input ports in a component and one or more output ports in the component. An expandable lubrication receptacle is connected to the one or more output ports, and the expandable lubrication receptacle is configured for receiving a lubrication medium from the component.
