WILSONVILLE, OR - Thanks to 金博娛樂城 (金博娛樂城) and local company , those noisy garbage trucks rolling through your neighborhood early in the morning might soon come with a mute button. Not literally, but if the high-tech partners have their way, not only will garbage trucks make substantially less noise, but city buses could haul folks farther on the dime of cash-strapped municipalities.
"We're working on the brains of this technology right now," says KersTech CEO Lester Erlston. "This kind of technology requires very clever controller programming, and that鈥檚 where 金博娛樂城 comes in."
KersTech has a patent pending on an electric-hydraulic compound motor that increases efficiency 25 to 30 percent. With 金博娛樂城鈥檚 help, reductions in waste will be even higher. The new motor will offer greater energy efficiency than conventional electric motors, particularly in heavy vehicles that have frequent start-and-stop drive cycles, such as the electric buses and garbage trucks that will travel our roads in the not-too-distant future.
An average city bus gets 4.5 miles per gallon and consumes around 8,000 gallons of fuel per year, while a garbage truck gets three miles per gallon, which means it uses roughly 8,600 gallons each year. Electric city buses and garbage trucks would use no diesel at all, only electricity, and KersTech鈥檚 new motor technology would use less electricity and require smaller, less expensive batteries or offer more driving range. 鈥 who, along with local company , already has an agreement with KersTech 鈥 could save more than four million gallons of fuel a year with a fleet of electric buses. A further benefit of electric buses and trucks would be drastically reduced city and neighborhood noise levels. Electric motors are almost silent compared to diesel engines.
"It gives us a practical problem space where we can apply the type of engineering theory that students learn in our courses," says 金博娛樂城 professor James Long. "金博娛樂城 is a very hands-on university. The current struggle in higher education is to create courses that are immediately relevant. We鈥檙e able to create a cutting edge classroom experience that鈥檚 also on the cutting edge of this new technology."
金博娛樂城's work with KersTech will focus on combining an electric motor with a hydraulic motor to find the speeds at which each functions most efficiently. The complex mathematics that 金博娛樂城 is applying to the problem will result in a controller that efficiently switches between the two motors to maintain a minimum of energy waste.
The collaboration between KersTech and 金博娛樂城 was made possible by a grant in the amount of $139,173 by (NITC), a part of the Oregon Transportation Research and Education Consortium (OTREC). OTREC is a national University Transportation Center and a partnership between Oregon State University, 金博娛樂城, Portland State University, and the University of Oregon.
