The word

Autocar E3 RunWiseThe garbage trucks use the hydraulic system made by PH that improves several portions of drivability including shifting and braking, which also reduces wear-and-tear on the truck and improves economy.

The RunWise system underwent a month of testing in South Florida this year and showed a whopping 72% improvement in fuel economy over its standard counterparts.

The average garbage truck's duty cycle will see a huge reduction in brake wear as well, dropping the maintenance period on brakes from an average of every six months now to over 2 years with the new system.

Parker RunWiseParker Hannifin's RunWise system is a hydraulic hybrid system capturing energy when the vehicle slows down or stops by pressurizing hydraulic fluid. This fluis is then released, reversing the process, and recovering the energy stored to assist the vehicle's forward movement or hydraulic systems use (such as the can lift on a refuse truck).

Vehicles which do a lot of stop-and-go driving benefit the most from this system. The RunWise system was unveiled in 2006 and has been gaining popularity world wide.

The Autocar company has been selling E3 heavy duty trucks with the RunWise system installed for over a year.

And so ...

This is a very innovative and easily retro-fitted way of greatly boosting economy in combustion vehicles that operate mostly in-town. Eaton-Fuller, Parker Hannifin's most direct competitor, is also developing a similar system.
