UPS Takes the Lead on Hydraulic Hybrids

    The delivery company will deploy seven trucks with a technology to challenge the electric hybrid—and may point the way for more green vehicles.

    Read page #2 as it will make you shake your head in disgust as to what we have given away :( -- Ed.

    Next year, UPS will deploy on U.S. streets a new model of its signature boxy brown truck. At first glance, it'll look no different than any of the company's 93,000 other delivery trucks. Inside the hulking chassis, however, will sit a hybrid technology that uses a hydraulic system in concert with a diesel engine to power the vehicle. The Environmental Protection Agency has received numerous patents on the system since 2000.

    Of seven test trucks, UPS will launch the first two in Minneapolis during the first quarter of 2009. They will join UPS's 1,600-truck "green fleet," which includes electric hybrids and natural gas trucks. For a company that uses nearly 1.5 million gallons of fuel each day in the U.S. alone, energy-saving technologies are welcome…

    Assisting the Diesel Truck Engine

    Similar to electric hybrids, hydraulic hybrids draw energy from braking, but are twice as efficient collecting that energy because the braking energy is not wasted by being passed into an electric motor. Instead, this energy is used to power a pump, which transports hydraulic fluid from a low-pressure reservoir to a high-pressure accumulator. As more fluid passes into the accumulator, the pressure grows, eventually being released as energy that is used to directly power the rear wheels. The hydraulic system replaces the driveshaft and traditional transmission… [rm][/rm]

    I assume you mean the part where a 2000 Ford Taurus with the hydraulic hybrid technology was getting up to 80 mpg... I don't see why that technology cannot be brought back to light vehicles today... Still, a shame that the current president cut funding on that program. I hope that it can be revitalized, better late than never...

    I can just see hyd. oil spills all over the roads. Wont that be nice to drive on. Hyd. systems are not very reliable and they tend to leak! Hope they fail! H
  4. Blame the war, not the president. The way the author worded it makes it sound like Bush just on a whim decided to reduce funding. No mention of the reason the funding was reduced...possibly a War on Terror??
    I guess if you write these things it pays in spades to blame the president.

    Anyway hopefully the funding will find a way to return.

    We're not paying for the war now. We've doubled the national debt since 2000. Before then we were paying down the debt.

    The idea that Bush has ever cared about limiting spending is not a reality.
    The idea that somehow a bill that was maybe a billion dollars max was cut to pay for the war is pure fantasy.
    We were not even at war when this was cut.

    Farm subsidies spending of course was increased after 9/11, again disputing your notion that this was somehow cut due to the war.

    This has been sop for republican party, Bush vetoed no spending bills when it was a republican controlled congress. This was killed because his buddies in the auto industry didn't want it. Any bills that came up through congress he passed, and played a large part in setting those bills up, and negotiating in congress before bills came up.

    Bush and the republicans have played a huge part in the failure of the auto industry due to cuts like this, that came well before 9/11. They pushed the ethanol BS on us again to help the agro industry and to give a crutch to the big 3.

    There are many hydraulic systems out there. Reliability?- how about airplane control systems and landing gear. And on the road systems are taking a beating now: Garbage trucks, dump trucks, low boy trailers, etc. all use hydraulic systems to operate their bodies.

    Regarding propulsion use for light duty vehicles/cars: doesn't seem to be the best application. Hydraulic systems that are pressurized can provide lots of power, but only for short bursts. Thats what makes them great for large vehicles in urban/stop and go operations.

    I hope they succeed.

    Lets not forget that almost every passenger vehicle on the road (excluding buses) have hydraulic brakes, and many have hydraulic power steering.
