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.
Steering assist comes from a
hydraulic system powered by an electric
pump, so it never lost pressure from low - speed
driving.
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.
With this new CVTi - S,
hydraulic pressure was reduced to an optimal point to protect against belt slippage, while conserving
drive effort to limit excess
pumping losses.
Under the normal, belt -
driven hydraulic power steering set up, a belt was attached to a series of pulleys (one at the crankshaft and one on the power steering
pump).
R&R Timing Belt,
Hydraulic Tensioner, Idler Pulley, Tension Pulley, set timing, change
drive belts, water
pump, inspect accessory pulleys, inspect Cam Seals.
The CR - V's all - wheel
drive system consists of the conventional front - wheel -
drive system, a compact transfer case that distributes torque to a propeller shaft running the length of the vehicle; the rear differential; an electronically - controlled
hydraulic pump; a multi-plate clutch; and left and right rear - wheel driveshafts.
Hybrid / EV / hydrogen battery (nickel - metal hydrate or lithium - ion
drive propulsion battery) including the case and mounting hardware, junction block, main battery cable, and frame wire; onboard battery charging system including charge controller, plug in outlets, plug in cable, and trickle charger cable; electric AC compressor and motor; electric steering rack, gear, and motor; electro /

This system uses a belt or camshaft
driven pump from the engine to pressurise a special
hydraulic fluid, which then powers the brakes, suspension and power steering.
As a result, components that would normally contribute to the greatest parasitic loss — driveshaft, ring / pinion, input clutch plates, servo -
hydraulic pump assembly and planetary gear sets — are all stationary when the vehicle is in front - wheel
drive.
[12] The
hydraulic pressure typically comes from a gerotor or rotary vane
pump driven by the vehicle's engine.
Another major advantage is the elimination of a belt -
driven engine accessory, and several high - pressure
hydraulic hoses between the
hydraulic pump, mounted on the engine, and the steering gear, mounted on the chassis.
The system is comprised of an upgraded, heavy - duty starter, an enhanced 12 - volt lead - acid battery, an electrically
driven transmission
pump that maintains internal
hydraulic pressure even with the engine off and an added electrically -
driven auxiliary water
pump to keep the climate control system operational while the engine is off.
Although throttle, steering, and braking are all in someway or another computer controlled, the CR - V's all - wheel -
drive system is controlled by simple
hydraulics that use pressure supplied by
pumps on the front and rear axles to determine torque split.
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.
It is the first time ever the Commodore will switch from using a motor -
driven hydraulic power steering
pump to a fuel - saving electric - assist system.
The power steering is electro -
hydraulic, with a conventional
hydraulic steering rack and electrically -
driven hydraulic steering
pump.
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 Oil scavenge
pump, to ensure stable oil supply in even in high G - force bends Liquid - cooled oil cooler for more efficient temperature control during high - load
driving Weight - saving hollow camshafts, which carry oil to the cylinder heads D - 4S (Direct - injection 4 - stroke gasoline engine Superior version), combining direct and port injection Electrically -
driven VVT - iE on intake, with mechanical inlet and
hydraulic outlet valves
Steering, which uses a
hydraulic system and electric
pump, feels tuned for a comfortable, easy
driving character.
The company's wave - power system acts as a sort of
hydraulic pump that converts the vertical motion of waves into pressurized sea water, which in turn
drives a piston that forces sea water through a turbine.
* Mechanical power, derived from the turbines, is applied directly through a speed increaser to an internal gearbox / generator, or to a
hydraulic pump that in turn
drives an on - shore
hydraulic motor and generator * Requires no dams nor impoundments * Poses no threat to the environment, nor to water quality * Produces no by - products while in operation - clean and pollution free (no greenhouse gases) * Harmless to marine life and allows safe fish passage
