The present disclosure relates to a method and system of maintaining a predetermined working quantity of fluid in a reduced volume sump of a motor or vehicle. The method includes recurrently determining a quantity of fluid in the sump and comparing the determined quantity of fluid to the predetermined working fluid quantity. In response to identifying a deviation between the determined quantity of fluid and the predetermined working fluid quantity, the method includes sending a control signal to a fluid pumping system to transfer fluid between the sump and a fluid container.

The present disclosure describes a drain plug structure for an oil pan for an internal combustion engine. The drain plug structure closes off a drain hole disposed in a bottom portion of the oil pan. The drain plug structure includes a columnar stopper portion inserted into the drain hole and rotated to prevent withdrawal. A sealing member is fitted to an outer periphery of the columnar stopper portion. An operating portion for a rotation operation is disposed on an outside exposed end portion of the columnar stopper portion. A plurality of cantilevered arcuate arm portions project radially outwards from the outside exposed end portion of the columnar stopper portion and are arranged in series along a circumferential direction. A loosening-prevention meshing portion is disposed on a tip end portion of each arcuate arm portion and an opening edge portion of the drain hole.

An air cleaner system that potentially reduces debris entering a prime mover (e.g., engine) during removal/replacement of an air cleaner. In one embodiment, the engine includes a shroud defining an air cleaner compartment. The engine further includes a tubular air feed port defining a combustion air intake. The air feed port terminates at an end face located at or within the air cleaner compartment, and a lower portion of the end face is notched relative to other portions of the end face. In other embodiments, an engine oil drain system is provided that selectively positions a distal end of an oil drain tube at a drain position located away from the engine. The oil drain tube may also be repositioned to a stored position, wherein the distal end of the drain tube attaches to a nipple connected to either an engine housing or surrounding structure.

A system. The system includes a valve assembly. The valve assembly includes a first port, a second port fluidically couplable with the first port upon application of negative pressure at the first port, a third port fluidically couplable with the first port upon application of positive pressure at the first port, and a first check valve positioned between the first port and the second port. The system also includes a second check valve fluidically couplable with the third port upon the application of the positive pressure at the first port. The second check valve is positioned external to the valve assembly.

The invention relates to a fluid drain plug (10) for a fluid reservoir (50) with a drain hole (51), the plug having an extension in an axial direction (A) and comprising a body part (16) rotationally insertable into the drain hole (51), the body part having a proximal axial end (15), a distal axial end (17) and a substantially circular cross section with an outer surface (18), wherein the body part comprises a drain channel (92) having an inlet (91) located at the distal axial end and an outlet opening (94) disposed on the outer surface (18), the body part further comprising a bayonet-type connection slot (40) for accommodating a part of a radial projection (52) of a circumferential surface surrounding the drain hole (51), the bayonet-type connection slot being disposed on the outer surface and comprising an entrance (40a) at the distal axial end, a first path (41) and a second path (42), the first path (41) extending from the entrance, in the axial direction (A) and in one circumferential direction (C), to a first path terminal portion (70), wherein the first path terminal portion (70) is adapted to accommodate the radial projection (52), and the second path (42) extending from the first path terminal portion, in the axial direction (A) and in an opposite direction to the one circumferential direction (C), to a second path terminal portion (72), wherein the second path terminal portion (72) is adapted to accommodate the radial projection.

An oil drain receptacle attachment, integrated system and method of use for providing a closed, clean catch system for the requisition of used motor oil for recycling. The oil drain attachment itself is positioned between a flexible drain tube and a collection receptacle where the reversibly attachable oil drain attachment allows for securing of the flexible tubing to an opening of the receptacle, in operation, that is capable of initiating and ceasing flow, through an ‘on’ and ‘off’ functionality, in addition to intermediate, partial opening and closing positions, as well as providing ventilation that facilitates the exit of air with the introduction of used oil into a collection receptacle for transportation and disposal.

An assembly is provided for a fluid system. This fluid system assembly includes a fluid conduit and a plug. The fluid conduit has an internal bore. The internal bore is configured as or otherwise includes a smooth-walled internal bore. The plug includes a protrusion and a head. The protrusion is connected to the head. The protrusion projects axially along an axial centerline partially into the smooth-walled internal bore to a distal end of the plug. The head is seated against the fluid conduit. The head seals an opening in the fluid conduit to the internal bore.

A system includes an oil catch compartment, at least one magnetic stud or rod, a motor compartment, and a switch. The oil catch compartment includes a first end configured for coupling to an oil filter. The at least one magnetic stud or rod is positioned along a sidewall of the oil catch compartment. The motor compartment includes a gearbox shaft and a puncturing device. The gearbox shaft is telescopically coupled to a second end of the oil catch compartment. The puncturing device is coupled to the gearbox shaft and positioned at least partially within the housing of the motor compartment or the oil catch compartment. The switch is formed on an outside surface of a battery compartment and communicatively connected to a motor coupled to the gearbox shaft. The switch is actuatable to cause the motor to advance the puncturing device via the gearbox shaft.
