Altair unveils world's first hydraulic-hybrid transit bus

The LCO-140H which means "low cost of ownership-first hybrid 40-foot" was developed under the program in partnership with BUSolutions Automation Alley, in an effort to revitalize the public bus transportation in America.

On the criteria of MPG, the CDO-140 achieved a fuel efficiency of the industry high of 6.9 mpg when tested using the center "stop-and-go" cycles work and a testing protocol established by the Federal Transit Administration (FTA) for certification testing of transit bus.

Now before you think MPG is low compared to assume that the database of the bus tested in Altoona, where the ALE certification program is conducted, the results LCO-140H fuel economy are impressive enough to 110 percent better than conventional diesel buses and 30 percent better than the first diesel-electric hybrid buses available today.

From an economic perspective, the total cost to be considered. On this front, BUSolutions is projected to lower the cost of ownership of $ 170,000 per bus, compared to a conventional diesel bus.With the local authority average transit operating about 300 buses, savings could reduce the cost of operating a city bus transit of about $ 50 million.

When compared to an estimated $ 27 million increase in the cost of operating a fleet of hybrid electric similar, it is clear that the LCO-140H could revolutionize the transportation industry by offering reduced fuel consumption and emissions while improving the financial performance of a regional transit.

Media Day

I was lucky, thanks to Jenn Korail wing.com, have met and interviewed Jeff Brennan, marketing manager for Altair to the MBS 2011 in Traverse City last month. His offer to participate in the event BUSsolutions was immediately accepted by me because of my interest in art, and he was in Troy, MI, not far from my home. Win-win!

Speakers at the event included James Scapa, president and CEO of Altair, Jeffrey Brennan, CMO, Altair, Mike Heskitt, COO, Altair, Martin Dober, Mich. Econ Corp in December, was for Maureen L.Brook Patterson, Oakland County Exec (who had a death in the family); Walter Kulyk, Federal Transit Administration, Ken Rogers, Automation Alley, and Louise Schilling, Mayor, City of Troy.

Parker Hydraulic piston pumps now incorporate proportional ...

A new range of hydraulic piston pumps has been launched to help reduce the size of the fan drive systems for both on and off road vehicles. Developed by Parker Hannifin, and based on the proven technology of the company pump piston P1, the new system has a dedicated proportional valve pressure control, integrated directly into the pump assembly. This effectively minimizes system size and weight, without affecting the overall performance or functionality, and enables design engineers to make the best use of available space on each vehicle, in addition, as part of the system hydraulic fan drive, the new system contributes to improved fuel efficiency and reducing emissions.

Parker says he "is the world's leading manufacturer of motion and control technologies and has developed a complete range of hydraulic and electrohydraulic for the automotive industry, especially off-road vehicles.In particular, the company has pioneered the use of hydraulic fan drive cooling for heavy equipment, as this provides considerable units. belt motor, for example, hydraulic systems offer the possibility to control the fan speed independent of engine speed, to provide significantly improved cooling efficiency and fuel economy. addition, hydraulic components for driving the fan can be located virtually anywhere on the vehicle, where space is available."

To date, however, the fan drive systems are generally composed of independent components, with the fan speed is variable by using a separate proportional pressure valve to control the pressure of the hydraulic motor system, although effective This solution takes an additional space and require additional piping and connectors.Â

To resolve this problem, Parker has developed versions of its hydraulic piston pump P1 that incorporate proportional pressure regulating valve in the assembly of the pump combination, which both minimize the number of individual parts and the necessary connections, reducing the overall space and installation and maintenance costs.
