A fluid pan for a motor vehicle has a main pan and a secondary pan that is separate from the main pan, wherein the main pan has a main space for fluid and a passage is provided on a side wall of the main pan. The secondary pan has a secondary space and an opening, wherein the secondary pan is attached to the side wall of the main pan in such a manner that the opening of the secondary pan connects to the passage of the main pan and thus the main space and the secondary space are fluidically connected.

A two-stroke engine comprises a first oiling system and a second oiling system. The first oiling system includes a low-pressure pump that distributes oil from a first oil tank to the two-stroke engine. The second oiling system includes a pump mechanically coupled to a crankshaft of the two-stroke engine, wherein the pump distributes oil from a second oil tank to an accessory at a pressure greater than the first oil pressure, wherein oil distributed to the accessory is returned to the second oil tank.

A lubrication system for an aircraft engine includes an engine lubricant tank including at least a supply port hydraulically connectable to the aircraft engine, a lubricant makeup port, and an overfill port, an auxiliary lubricant tank, a lubricant makeup conduit hydraulically connecting the auxiliary lubricant tank to the lubricant makeup port. The lubricant makeup conduit includes a pump operable to move lubricant from the auxiliary lubricant tank to the lubricant makeup port, and an overfill conduit hydraulically connecting the overfill port to the auxiliary lubricant tank. A method of operating a lubrication system of an aircraft engine of an aircraft is also disclosed.

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 system is provided. The system includes a reciprocating engine configured to consume oil at or less than 0.25 g/kw-hr and to use makeup oil. The reciprocating engine includes an engine oil sump. The system is configured to maintain an oil volume in the reciprocating engine during operation so that a residence time of oil in the reciprocating engine is at or less than 1000 hours.

A lubrication system for a machine such as a mobile generator, a mobile light tower, or a mobile jobsite heater implements an engine oil supplementation strategy from an auxiliary sump to increase service time between engine oil servicing tasks of an internal combustion engine. The system periodically introduces a supplemental volume of oil from an auxiliary sump into the engine's lubricating system during an oil supplement event. The fluid communication between the engine sump and auxiliary sump may be achieved through multiple sump connections, which may include a sump-to-sump return line that provides a liquid connection allowing oil to freely flow between the engine sump and the auxiliary sump and a vent line that provides a gaseous connection between a void space at an upper end of the auxiliary sump and a void space at an upper end of the engine sump.

A lubrication system for an aerial vehicle, the lubrication system including: a lubrication oil (LO) tank configured to operate at a first internal pressure; and an intake chamber (IC) configured to operate at a second internal pressure greater than the first internal pressure, the IC including an ingress port configured to receive LO from a sump of an equipment of the aerial vehicle; an overflow port in fluid communication with the LO tank; and a supply port in fluid communication with the sump and configured to supply LO to the sump.

The first oiling system includes a low-pressure pump that distributes oil from a first oil tank to the two-stroke engine. The second oiling system includes a pump mechanically coupled to a crankshaft of the two-stroke engine, wherein the pump distributes oil from a second oil tank to an accessory at a pressure greater than the first oil pressure, wherein oil distributed to the accessory is returned to the second oil tank.

A scavenging pump is utilized to draw oils from a catch tank that collects the oils supplied to components to an oil pan that reserves therein the oils. The scavenging pump includes gears to draw the oils, and a housing that stores therein the gears. An oil receiving portion capable of receiving the oils injected from the exterior is formed in an outer circumferential surface of the housing, and an oil introducing hole that introduces the oils injected to the oil receiving portion into the interior is opened at a position continuous from a lower part of the oil receiving portion and facing the gears.
