World's First Fully Active, Regenerative Suspension for Automobiles

1. It's only a matter of time before cars' suspensions become a part of the electric power-regeneration process (similar to regenerative braking). ZF Friedrichshafen AG and Levant Power Corp. Levant Power is developing GenShock-technology( see Supplement p.???? ) , the first active suspension system with the ability to recapture energy. They are promoting efficient innovations that are tailored to meet global requirements.

2. The active dampers employ a new type of valve technology to regulate the flow of oil in the shocks, which is the basis for the active and regenerative characteristics. The technology is contained in a device mounted to the outside of each shock. The device houses its own control unit, an electric motor and an electrohydraulic gear pump, and controls the flow of fluid in the shocks to adjust the damping rate, like a normal active damper.

3. The process is reversed when the shock is regenerating energy. As the vehicle is traversing uneven terrain or is unsettled in a turn, during acceleration or while braking, the swaying motion of the piston in the damper pushes fluid past the electrohydraulic gear pump, which drives the electric motor and converts the kinetic energy into electricity that is fed back into the power supply. A system like this would function better on poor road surfaces. The rougher the road surface, the more movement the damper experiences, which generates more electricity. Ride and handling are at the core of the driving experience.

4. GenShock-technology is a fully active system for passenger cars which combines dynamics, safety and comfort characteristics with minimum energy consumption.
Automakers have long sought a suspension that allows sport cars handling while maintaining thecomfort of a premium luxury sedan. But comfort requires a soft suspension to absorb bumps, while handling requires stiffness for control. And it should mentioned that ride and handling are at the core of the driving experience. Previous attempts to achieve high-bandwidth activesuspension have fallen short due to cost, complexity and power consumption. ZF and Levant Power are now developing GenShock-technology to unite the vast gains of active suspension with modest power consumption, minimal complexity and affordable cost.

Exercise 4. Translate the following sentences paying attention to the suffix- ing

Participle

1. Lithium-ion systems also offer a far greater charge acceptance rate than lead acid, allowing the battery to capture more of the vehicle's energyduring deceleration/ braking and store it to support electrical loads when the engine is off.

2. Tesla Motors has patented a new battery system, pairing metal-air and lithium-ion batteries, and their future car models may also reach a range more than 400 miles per charge.

Gerund

3. Manufacturers and suppliers have offered different solutions, but few succeeded in combininga remarkable improvement on handling performance, low energy consumption, simplicity and low cost.
