- Freightliner Custom Chassis commitment for 20 series hydraulic hybrid
systems for delivery vehicles represents milestone in technology's
commercialization










CLEVELAND, Oct. 16 /PRNewswire-FirstCall/ -- Parker Hannifin Corporation
(NYSE: PH), the global leader in motion and control technologies, today
announced initial commercial commitment for its new series hydraulic hybrid
system, which is designed to completely replace the traditional drive train on
delivery vehicles and has yielded significantly increased fuel efficiency and
reduced carbon emissions. The commitment came as part of a grant under the
United States Department of Energy's Clean Cities program and was funded
through the American Recovery and Reinvestment Act.  


Daimler Trucks North America LLC (DTNA) spearheaded the submittal of these
winning applications which will support the purchase of 638 hybrid and
alternative fuel vehicles.  Parker is the only supplier of the hydraulic
hybrid systems for the vehicles. The systems will be purchased by DTNA
subsidiary, Freightliner Custom Chassis Corporation and incorporated into
delivery vehicle models intended for use by United Parcel Service (UPS).


"This is a significant development in the advancement of this new hydraulic
hybrid system, one of several technology platforms on which we are currently
working," said Don Washkewicz, Chairman, CEO and President of Parker.  "The
commercial application of our technology is recognition that our system has
demonstrated several unique advantages over electric hybrids including
significantly better fuel efficiency. Importantly, with products from Parker
divisions across geographies, this system is a shining example of our ability
to leverage our existing technologies to build complete systems and address
some of the most pressing and current engineering challenges of our time, such
as the need to decrease energy consumption and reduce our environmental
impact."


Field testing of the system during the past year has indicated that the
hydraulic system is capable of generating as much as a 50 to 70 percent
increase in miles per gallon in stop-and-go applications when compared with
traditional diesel powered vehicles that have automatic transmissions. Prior
to field testing, the system was validated for fuel efficiency by the United
States Environmental Protection Agency at its National Vehicle and Fuel
Emissions Laboratory in Ann Arbor, Michigan.


The series hydraulic hybrid system is unique in that the engine is not
connected to the rear wheels of the vehicle. This de-coupling of the engine
from the drive wheels offers several advantages including: the ability to
recover and store energy from braking, thus reducing brake wear; an engine
management system that optimizes the vehicle's engine for reduced fuel
consumption; drive the vehicle with the engine off, significantly reducing
carbon emissions in depots and at delivery points, contributing to reduced
fuel consumption. 


"We are on the cutting edge of advancements in series hydraulic hybrid
technology working in close partnership with customers such as Freightliner
Customer Chassis Corporation to commercialize new systems," commented Dr. Joe
Kovach, Group Vice President of Technology and Innovation for Parker's
Hydraulics Group. "We believe the series hydraulic hybrid technology has
application not only in delivery vehicles, but also for yard hostlers and city
buses. Additionally, our advanced series hydraulic hybrid system, called
RunWise(®), is currently being field tested in more demanding applications
such as with refuse vehicles. This is a technology that holds great promise as
a contributor to reduced environmental impact and increased fuel efficiency." 


The Parker series hydraulic hybrid system stores energy recovered during the
braking process in an advanced accumulator. The energy stored in the
accumulator is then used to accelerate the vehicle on the next launch. Once
that energy is depleted, the engine is restarted. Unlike electric-hybrid
systems which store energy in a battery, the series hydraulic hybrid can
recover and reuse as much as 70 percent of the energy used from braking that
otherwise would be lost energy. By comparison, traditional electric systems
can recover only 20 to 25 percent of brake energy. The system is one of a
growing range of technologies Parker is developing to address energy-related
challenges, with systems in development for renewable energy applications such
as wind, solar and wave; and in making traditional energy more efficient.
