Systems, apparatus, and methods are disclosed that include an internal combustion engine having a lubrication system with an upper storage reservoir for receiving lubrication fluid from the internal combustion engine. The upper storage reservoir maintains a supply of lubrication fluid to a lower storage reservoir even while the internal combustion engine is inclined due to operation along severe grades. The lower storage reservoir supplies fluid for circulation to the internal combustion engine.

An inverted non-stop apparatus includes a lubricating system and a breathing system. The lubricating system includes a machine body, an engine oil pump, and an oil pan. A cavity of the oil pan is divided into an oil collection groove and an oil tank body. A flange is provided to form an enclosed lubricating oil tank. The engine oil pump is a double pump including a lubricating pump and an oil return pump. An oil suction port of the oil return pump is connected to the bottom of the oil collection groove, and an oil outlet is connected to the lubricating oil tank. An oil inlet of the lubricating pump is connected to the lubricating oil tank, and an oil outlet is communicated with a main oil path of the machine body. A breathing one-way valve and an air pressure relief valve are provided on the oil tank cover.

An evaluation of the oil level of an aircraft engine tank from doses of oil delivered from another tank by a pump can be checked by comparing the evaluation of the volume provided by a sensor associated with the engine tank with an estimation of the volume extracted from the aircraft rank, either by another level sensor associated with this tank, or directly from the control of the pump. This comparison is made by a module capable of notifying staff of the need to check or maintain the device, and in particular to check if the sensor is operating correctly. Application to aeronautics, in particular to devices wherein a single aircraft tank supplies all the engine tanks.

A lubrication system for a transmission assembly includes a primary reservoir, at least one primary jet, a primary circulating system fluidly coupling the primary reservoir and the at least one primary jet, a secondary reservoir, at least one secondary jet, and a secondary circulating system fluidly coupling the primary reservoir and the at least one secondary jet and fluidly coupling the primary reservoir and the secondary reservoir.

An inverted non-stop apparatus of a multi-cylinder diesel engine for a free-fall lifeboat is provided. The apparatus includes a lubricating system and a breathing system. The lubricating system includes a machine body (101), an engine oil pump, and an oil pan (118). The breathing system is a diesel engine breather. A partition board (1181) is transversely provided in the oil pan (118) to divide a cavity of the oil pan (118) into a left cavity and a right cavity. The left cavity is an oil collection groove (1182), and the right cavity is an oil tank body (127A). A flange is provided at an opening of the oil tank body (127A) for fixing an oil tank cover (125) to form an enclosed lubricating oil tank (127). The engine oil pump is a double pump having oil inlets and outlets independent separately, which is formed by superposing upper and lower layers, wherein the upper layer is a lubricating pump (111) and the lower layer is an oil return pump (112). An oil suction port (114) of the oil return pump (112) is connected to the bottom of the oil collection groove (1182), and an oil outlet is connected to the lubricating oil tank (127). An oil inlet of the lubricating pump is connected to the lubricating oil tank (127), and an oil outlet is communicated with a main oil path (102) of the machine body. A breathing one-way valve (132) and an air pressure relief valve (131) are provided on the oil tank cover (125). The inverted non-stop apparatus of a multi-cylinder diesel engine for a free-fall lifeboat separate an engine oil collection function and an engine oil storage function borne by an oil pan of a diesel engine, so that no matter the diesel engine is longitudinally and transversely turned over and inverted, the diesel engine can operate normally.

Oil supply system for an internal combustion engine, whereby an internal oil pan is arranged in the internal combustion engine, whereby the oil supply system has an additional external oil reservoir which is arranged outside the internal combustion engine compared to the internal oil pan of the internal combustion engine, whereby a supply line to be connected to the internal combustion engine is provided, which leads to a filling opening of the oil reservoir, and whereby a return line to be connected to the internal combustion engine is provided, through which oil can be returned from the oil reservoir to the internal combustion engine, whereby the return line is connected to the oil reservoir and whereby the oil reservoir has at least one oil tank, whereby a removal opening of the return line is arranged near or in the base of the at least one oil tank.

An engine assembly includes an air-cooled engine and an external oil reservoir. The engine includes a vertically-oriented crankshaft a crankcase cover having a front portion and a rear portion, wherein the front portion of the crankcase cover and the cylinder head are located forward of a vertical plane that includes the crankshaft axis, a return pump housing formed in the exterior of the crankcase cover, a return pump positioned in the return pump housing, and a return pump inlet formed through the crankcase cover, wherein the return pump inlet is located in the front portion of the crankcase cover and the return pump inlet is located closer to the camshaft than to the crankshaft. The external oil reservoir includes an oil tank and an oil filter assembly.

An apparatus comprising: an identity determiner configured to determine an identity of a removable fluid container; a characteristic determiner configured to obtain a first characteristic based on testing the fluid of the fluid container; a data obtainer configured to obtain a second characteristic based on the identity; and a processor configured to control a fluid provider to provide fluid from the removable fluid container based on the comparison of the first characteristic and the second characteristic.

A method is described of supplying liquid to a liquid delivery system in a vehicle. A a replaceable liquid container including a reservoir containing liquid is releasably coupled in the vehicle to provide fluidic communication between the reservoir and a liquid delivery system of the vehicle during operation of the vehicle. The method includes the steps of: (i) prior to establishing liquid communication between the reservoir and the liquid delivery system of a selected vehicle, communicating with a data carrier carried by the container and determining data associated with at least one of the container and its contents; and (ii) using the data in an analysis of suitability of the container and/or content of the container for the selected vehicle and generating a suitability output, and (iii) establishing liquid communication between the reservoir and liquid delivery system of the selected vehicle in dependence on the suitability output.
