A fluid delivery system for supplying fluid to at least one machine assembly, in particular an engine and/or transmission of a motor vehicle, including: a first pump and a second pump; a drive for driving the first pump and/or the second pump; a reservoir for storing the fluid; and a filter module for filtering the fluid, wherein the first pump delivers fluid from the reservoir to the machine assembly in a supply flow and the second pump is arranged downstream of the machine assembly and delivers at least some of the fluid into the reservoir in a sub-flow downstream of the machine assembly and the filter module is embodied in the sub-flow.

A fluid delivery system for supplying fluid to a machine assembly includes: a pump module; a drive for the pump module; and a housing which includes a reservoir for the fluid. The reservoir includes an aspiration point, and the pump module includes a first inlet, a second inlet, a first outlet and a second outlet. The first inlet is fluidically connected to the reservoir via a first suction conduit, and the first outlet is fluidically connected to the machine assembly via a first pressure conduit. The second inlet is fluidically connected to the housing via a second suction conduit, and the second outlet is fluidically connected to the reservoir via a second pressure conduit.

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.

Described is a cooler having: a heat exchanger for dissipating heat from a medium, for example oil, a fan having a fan housing, a fan wheel and a motor, a control unit for controlling the motor, a sensor unit for detecting an operating parameter of the heat exchanger and/or of the fan, the sensor unit being connected to the control unit in order to set an operating state of the cooler, the fan housing having a recess in which the control unit is arranged together with the sensor unit.

An internal combustion engine including a crankcase and a cylinder head are described, including at least one cylinder block, at least one flat flange surface for accommodating at least one oil cooler, at least one oil cooler, at least one coolant inlet to the oil cooler, at least one coolant outlet from the oil cooler, and at least one internal cooling section.

Oil distribution blocks and oil distribution systems equipped therewith. Such an oil distribution block includes a rigid block body configured to be secured to a cylinder head of an engine, an oil inlet, and an oil outlet. The oil inlet is configured to be releasably coupled to a first oil distribution line or a fitting therebetween, receive a flow of oil therefrom, and route the oil to an inlet of a cooling passage of the cylinder head. The oil outlet is configured to be releasably coupled to a second oil distribution line or a fitting therebetween, receive a flow of oil from an outlet of the cooling passage of the cylinder head, and route the oil to the second oil distribution line. The oil inlet and the oil outlet are configured to threadably couple with the first and second oil distribution lines, respectively, or the fittings therebetween.

An additive manufactured heat exchanger includes a monolithic housing defining an outer surface, a plurality of first fluid passageways extending between a first fluid inlet and a first fluid outlet, and a plurality of second fluid passageways extending between a second fluid inlet and a second fluid outlet. A cross section of the outer surface defines an irregular shape, the plurality of first fluid passageways and the plurality of second fluid passageways define a convoluted flow matrix within the monolithic housing, and the outer surface of the monolithic housing is complimentary to a space between at least two components of a vehicle. The monolithic housing can also include a plurality of third fluid passageways extending between a third fluid inlet and a third fluid outlet.

A marine cooling system performs a temperature adjustment of an object to be cooled such as an internal combustion engine of a marine vessel. The marine cooling system includes a water supply flow passage to supply cooling water to the object, a water drain flow passage to drain the cooling water from the object to reduce an amount of the cooling water that contacts the object, and a flow passage controller to shut off the water to the drain flow passage.

An internal combustion engine including a crankcase and a cylinder head are described, including at least one cylinder block, at least one flat flange surface for accommodating at least one oil cooler, at least one oil cooler, at least one coolant inlet to the oil cooler, at least one coolant outlet from the oil cooler, and at least one internal cooling section.

A recreational off-highway vehicle includes a vehicle frame, a plurality of wheels, a drive source, a vehicle body and a pair of headlights. The vehicle frame includes a front frame, a rear frame and an intermediate frame defining an open passenger compartment between the front and rear frames. The wheels support the vehicle frame. At least one of the wheels is a drive wheel. The drive source supported by the vehicle frame. The vehicle body is provided to the vehicle frame. The vehicle body includes a front grille panel that has an air intake area defined by a plurality of intake air openings. The headlights are located primarily at a middle point of the front grille panel with respect to a vertical direction of the recreational off-highway vehicle.
