So when the vehicle needs to move forward, the operator hits the gas pedal, but the computer sees that and says "Ok, I will use some of this stored hydraulic pressure to move the truck." When the hydraulic pressure gets too low, the diesel engine kicks in to get the pressure back up, but it dose so at the diesels sweet spot, which is independent of the speed of the vehicle.

If that's the case, city driving would seem sort of difficult or you'd just be driving high in 2nd gear for long periods of time. I have a 5-speed Civic Si and i'd be shifting at somewhere around 20mph to get to second and 50mph to get to third gear. By the time I am hitting 6000 RPM, that car is booking. It doesn't seem very safe.]]>Dec 27th 2008 8:51AMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/
My question is, at 600 rpm, will the engine's pump-pressure (e.g. the air it pumps in to the tanks) match the usage of the car when at full speed? You would not want to run out of air on the middle of a highway!]]>Dec 27th 2008 5:47PMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/Dec 27th 2008 5:48PMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.popsci.com/cars/article/2002-01/350-horsepower-hydraulic-assisted-hot-looking-tonka-truck]]>Dec 27th 2008 7:36AMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/Dec 27th 2008 9:05AMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/@Bob w00t +1]]>Dec 28th 2008 3:46PMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/

Aside from the pieces that interact with the drive train, the storage tanks are good old highly recyclable steel containers.

Hydraulic drivetrains don't put traditional drivetrains in jeopardy, because hydraulic drivetrains become very inefficient when you want to move rapidly. Ask anyone who has driven a materials handler about it.]]>Dec 27th 2008 8:24AMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/

This system though sounds a bit iffy. It requires a lot of load on hydrolic pumps, motors, and lines continuously... not just for breaking. Cooling will likely be an issue. It will likely take a full radiator and fan, not just the little transmission cooler used in automatic transmissions now. Think of the mess you would have when the system develops a leak. I have seen hydrolic line rupture at work.... oh my.]]>Dec 27th 2008 10:54AMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/Dec 27th 2008 12:11PMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/Dec 27th 2008 2:14PMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/Glad to see someone actually doing it though!

Still, if this is anything like their superchargers on the Cobras, it'll be a bad ass stock system, and will be easily upgradable for mere pennies, but will still be inefficient compared to aftermarket options, and most people will swap out to a bigger and better system. (This is sarcasm before someone replies telling me how it wont be inefficient or something, other Cobra guys will get it)]]>Dec 27th 2008 2:29PMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/Dec 27th 2008 4:58PMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/Dec 27th 2008 8:07PMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/Dec 27th 2008 10:29PMhttp://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/http://www.engadget.com/2008/12/27/eatons-fuel-saving-hydraulic-hybrid-systems-put-traditional-dri/
