A fan drive gear system for a turbofan engine is disclosed and includes a gear assembly and a front center body. The front center body is an annular case that supports the gear assembly. The front center body includes a passage portion that defines a portion of a core flow path, a forward flange configured for attachment to a first case structure forward of the front center body, and a gutter portion disposed on a radially inner side of the front center body for collecting lubricant exhausted from the geared assembly.

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 motor unit includes a motor including a rotor to rotate about a motor axis, and a stator radially outside of the rotor, a reduction gear connected to the motor, a differential connected to the motor through the reduction gear, a housing including a housing space to house the motor, the reduction gear, and the differential, and an oil passage to lead an oil to the motor. The oil passage includes an electric pump and a cooler. The electric pump and the cooler are fixed to the housing. The electric pump includes a portion located vertically below the cooler.

A method for operating an internal combustion engine that is supplied with lubricating oil via an oil circuit. A measurement value of the total base number and/or a measurement value of the oxidation of lubricating oil currently used in the oil circuit for the lubrication is detected. Dependent on the established measurement value of the total base number and/or dependent on the established measurement value of the oxidation an exchange oil quantity for the oil circuit is determined. Currently used lubricating oil to an extent corresponding to the exchange oil quantity is removed from the oil circuit and new lubricating oil to an extent corresponding to the exchange oil quantity is supplied to the oil circuit.

A vehicle is provided which can reduce an influence on an occupant space due to location and arrangement of an inverter. The vehicle includes a longitudinal engine, a motor, a transmission, and an inverter. The motor is located behind the longitudinal engine. The transmission 13 has a transmission casing and is adjacently located behind the motor. The transmission is arranged below a floor tunnel. The inverter is mounted below the floor tunnel and on an upper portion of the transmission casing.

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.

A method for operating an internal combustion engine wherein the internal combustion engine to be operated is supplied with lubricating oil via an oil circuit. A measurement value of a total base number and/or a measurement value of the viscosity of the lubricating oil currently used in the oil circuit for the lubrication is detected. Dependent on the established measurement value of the total base number and/or dependent on the established measurement value of the viscosity an exchange oil quantity for the oil circuit is determined. Currently used lubricating oil to an extent corresponding to the exchange oil quantity is removed from the oil circuit. New lubricating oil to an extent corresponding to the exchange oil quantity is supplied to the oil circuit.
