摘要： An oil pan for an engine comprises a containment portion of unitary construction. The containment portion has a circumferential component defining a circumferential extent of the containment portion and comprising a pair of mutually opposing side walls. The containment portion also comprises a base wall extending inwardly from a first portion of the circumferential component and defining a lower extent of the containment portion. The oil pan also comprises an attachment portion comprising an attachment surface at a second portion of the circumferential component; a first plug portion on an interior of a first one of the pair of mutually opposing side walls at a first location; and a second plug portion on an interior of a second one of the pair of mutually opposing side walls at a second location. The first and second plug portions are configured to receive an oil syphon connector and the attachment portion has a rotational symmetry such that the attachment surface is connectable to an engine block in a first orientation and in a second orientation. The first and second plug portions are located such that an oil tube having a fixed location relative to the engine block aligns adjacent the first plug portion on attachment of the attachment portion to the engine block in the first orientation and aligns adjacent the second plug portion on attachment of the attachment portion to the engine block in the second orientation.

摘要： An internal combustion engine includes: a crankshaft; a crankcase that supports the crankshaft; an oil tank that is at least partially partitioned by the crankcase; a scavenge pump including a first intake port and a first discharge port; a feed pump including a pump shaft, a second intake port and a second discharge port, oil that has been sucked in through the second intake port as the pump shaft rotates being discharged through the second discharge port; a scavenge discharge passageway connecting the first discharge port of the scavenge pump to the oil tank; and a feed intake passageway connecting the oil tank to the second intake port of the feed pump. As viewed from the axial direction of the pump shaft, at least a portion of the feed pump and the oil tank overlap each other.

摘要： 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.

摘要： 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.

摘要： An internal combustion engine includes a first blow-by gas passage defined in a second wall. The internal combustion engine includes a second blow-by gas passage defined in a third wall. The internal combustion engine includes a third blow-by gas passage defined in a fourth wall. The first blow-by gas passage to the third blow-by gas passage connect an oil chamber and an oil separator to each other. The second wall includes a first connecting path. The fourth wall includes a second connecting path. The first connecting path connects the first crank chamber and the second crank chamber. The second connecting path connects the third crank chamber and the fourth crank chamber to each other. The third wall does not have a passage connecting the second crank chamber and the third crank chamber to each other.
