A lubrication system for extending times period between changing engine lubricant may include a tank and a lubricant exchange apparatus. The lubricant exchange apparatus may comprise a first pump in fluid communication with the engine and the tank to transfer lubricant from the lubricant collection element to the tank, a second pump in fluid communication with the tank for transferring lubricant from the tank to the engine, and a control element configured to cause the first pump to operate to remove lubricant from the lubricant collection element. The control element may be configured to cause the second pump to operate to remove a quantity of lubricant from the tank and transfer the quantity to the engine.

A zero turning radius mower oil extension kit includes a supplemental oil tank that may be installed under a wet sump of a zero turning radius mower engine. A plurality of conduits may be installed between the supplemental oil tank and at least one drain port of the engine for continuously circulating a volume of oil between the supplemental oil tank and the wet sump of the engine while the engine is running. The kit extends the time between oil changes because of the increased volume of oil in the supplemental oil tank and the wet sump.

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 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.

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 mechanical system comprising a sump and at least one component to be lubricated or cooled arranged in the sump, the mechanical system comprising a lubricating fluid system provided with a lubricating fluid and a tank arranged in the sump. The tank is a leaking tank and is situated above said at least one component to be lubricated or cooled, the lubricating fluid flowing out of the tank by force of gravity, so as to reach said at least one component to be lubricated or cooled. The lubricating fluid system has at least one lift flow generator connected by at least one filling line to the tank and to at least one suction point present in a bottom of the sump. The lift flow generator fills the tank with the lubricating fluid present in said bottom at least during a starting phase.

An oil cooling assembly for an All-Terrain Vehicle (ATV) and a method of improving the efficiency of the ATV's cooling system is provided. The assembly or kit may include a relocating bracket that can be used to affix the original equipment manufacturer (OEM) oil cooler to a front portion of the ATV after the OEM oil cooler is removed from underneath the ATV frame. The kit may include a new reservoir tank that is larger than the OEM oil tank, as the relocation of the OEM oil cooler affords more spaced to accommodate the larger reservoir tank. The kit includes fluid conduits and barbed fittings to fluidly connect the relocated oil cooler to the reservoir tank, the reservoir tank to the motor, and the motor to the relocated oil cooler.

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.
