Biglorryblog is in debt to John Walsh of MackTrucks who has very kindly answered my call for a picture of this splendid beast---the Mack TerraPro Low Entry diesel electric hybrid refuse truck which has just entered service with the US Airforce Advanced Power Technology Office (APTO) at APTO at
The TerraPro hybrid has a rear loading refuse packer body and is equipped with a 325 hp U.S.'07-compliant Mack MP7 engine (which if Biglorryblog recalls correctly is based on the Volvo D9 diesel). The Mack hybrid-electric powertrain used in the truck features an integrated starter, alternator and motor that assists the MP7 in providing torque to the wheels and regenerates energy during braking. The energy captured during braking -- stored as electricity in lithium ion batteries -- then is used in place of diesel fuel and helps launch the truck from stops. Now click through here for more...
Mack says its diesel electric hybrid technology provides the maximum fuel savings on routes with frequent braking and accelerations. Which means that in addition to refuse collection work it's good for urban delivery runs and certain construction applications. indeed, on the right mission Mack reckons its hybrid system can boost fuel economy by 20-30% whilst cutting greenhouse emissions and the cost of maintenance.
"Mack shares the Air Force's commitment to reducing both the country's dependence on fossil fuels and imported oil, as well as the impact of truck operations on the environment," Dennis Slagle, president and CEO of Mack tells Biglorryblog. "The vehicles we're producing under this partnership are a key stepping stone to offering commercially viable hybrid-electric vehicles to our customers."
The TerraPro truck underwent extensive testing of the hybrid system prior to delivery, with several thousand accumulated miles of operation. After APTO reviews and tests the truck, they'lll provide it to the City of Macon, Georgia, for continued testing in their municipal waste collection operation. The trials are part of an agreement between APTO, the City of
Nothing new here Brisbane city bus fleet had R.e.g the bus which is now stored for display by the bus club.. It works the same way using braking force to generate power stored for lift of helping hand, all simple stuff no Doubt the new one has a lot more computor aided control as REG was made in the repair shops here in Brisbane Queensland and saw service with trianed drivers about the city, a tad heavy with two fork lift batteries under the floor and wheel motors at the rear but proved the point.
