Truckers Moving to Hybrids, But Not Electric Ones

According to a Thomson News edge online report quoting the publication Design News:

"Researchers at the U.S. Environmental Protection Agency’s Office of Transportation and Air Quality have developed a hybrid in conjunction with Eaton Corp., the Southwest Research Institute and other partners, the report noted. Since June 2006, this system has been under evaluation on a UPS delivery truck in Detroit. The EPA has also worked on aspects of hydraulic hybrid design with Parker Hannifin under a separate cooperative research and development agreement, the report noted."

"The EPA has opted to offset the efficiency loss during highway driving differently than Parker. Weve redesigned the pump-motors to get more efficiency than we could with an off-the-shelf model, Kargul says. For example, EPA researchers created a pump-motor design with higher displacement angles than most off-the-shelf bent-axis pump-motors the type used to drive the rear wheels. Our pumps displacement angles in the 45-50 percent range in the same package size as off-the-shelf pumps with displacement angles in the 20 to 25 percent range, says Kargul, noting bent-axis pump-motors run most efficiently with higher displacements."

"The main difference between EPAs UPS truck and Parkers in-house hybrid design comes down to the use of a secondary mechanical direct drive system for the rear wheels under certain driving conditions. In the EPAs full-series hybrid, only the hydraulic system connects the diesel engine and rear wheels. Parker, by contrast, augments the hydraulic drive train with a mechanical direct drive system that connects the engine to the rear wheels during highway driving, meaning steady state speeds of 50 mph or so."

Where have we heard this before?
Oh, that's right at TORVEC.
I think that JG had been the first to mention all of this.
Here's to the Torvec patents.
