However, the rear wheels can be engaged in fractions of a second whenever necessary via the center differential, which is activated by an electro -
hydraulic oil pump.
Also, the new system will be joining the present eight - speed transmission used for Kia models with rear - wheel drive, featuring smaller
hydraulic oil pump or a high - performance direct control valve body with 12 valves out of 20, which reduce shift times; it allows as well a 34 percent ratio increase over the six - speed automatic, improving thus acceleration and fuel economy.
According to Volkswagen, it uses the latest generation Haldex - 5 coupling, which is activated by an electro -
hydraulic oil pump.
This is done by means of the Haldex coupling that is activated by an electro -
hydraulic oil pump.
The multi-plate clutch at the heart of the Golf R's Haldex 5 all - wheel drive system is familiar enough, using an electro -
hydraulic oil pump to engage and send almost 100 percent of available torque to the rear axle when a control unit deems it necessary.
What is it: The Volkswagen Golf Alltrack wagon uses a 1.8 - liter turbo - four for power and comes with VW's 4Motion all - wheel drive using a Haldex - 5 coupling and an electro -
hydraulic oil pump.
I think this person is taking about the pressure relief valve which is relieving hydraulic fluid pressure created by the transmissions
hydraulic oil pump.
Not exact matches
Other human activites linked to seismic activity include
hydraulic fracturing, in which a water mixture gets
pumped underground to break up rocks and release gas, and fluid withdrawal, which can refer to the withdrawal of
oil and gas, groundwater or hot water / steam for geothermal power, the USGS says.
But according to a panel of geologists at the AAAS Annual Meeting, the culprit isn't
hydraulic fracturing, or «fracking,» in which geologists crack open subsurface rocks to extract
oil and gas; instead, it's the processes associated with
pumping wastewater and other fluids back into the ground.
An electric
pump supplies the VAQ unit with varying degrees of pressurised
hydraulic fluid; this
oil operates a pack of clutches that can lock the driveshaft to the diff cage, and therefore, essentially, the other driveshaft too.
Have into account two factors:
oil viscosity may be much or very much higher than the antifreeze fluid (glicol - polipropylene derivates) normally used: the radiator grille has capilare - thickness tubes and an
hydraulic circuit (
pump, filter, reservoir...) prepared for much less viscosity.
An electric
oil pump makes operation of the Q7's start - stop system possible: it maintains
oil pressure in the
hydraulic circuit when the engine stops, and closes the clutch for restarting.
As on the M3 engine, the VANOS system has its own
hydraulic pump; this contrasts with BMW's regular - production engines, whose VANOS draws its pressure from the main
oil pump.

The regulated vane - type
pump, which supplies the system with
hydraulic energy, always delivers only as much
oil as is needed; in this way it too contributes towards high consumption efficiency.
Key elements include: - Aluminium block with built - in reinforcements High - flow intake ports and high - speed, high - lift valvetrain to enable high engine speed and power Compact intake fuel surge tank to increase engine response

Fracking, or Fracing as the
oil and gas industry ungrammatically spells it, is short for
hydraulic fracturing, and the technology is now being used extensively to extract shale gas, by
pumping liquids at high pressure into the rock, creating and expanding fissures.
