‘RunWise’ with ISL G Saw Testing with Republic Services,
Numerous Further Fleet Evaluations Planned for This Year
Parker Hannifin and partner Autocar have added compressed natural gas fuel to an Autocar E3 trash truck with Parker’s fuel and brake-saving RunWise hydraulic hybrid drive. More than 100 of the commercial diesel-fueled hydraulic hybrids have been placed with refuse operators.
The CNG-fueled engineering prototype, with Heil body, has been run through month-long initial trials with Republic Services in Chula Vista, Calif.
The vehicle has an 8.9-liter ISL G engine from Cummins Westport.
“We are pleased with the initial results of the CNG-powered RunWise refuse trucks,” Parker Hannifin hybrid drive systems division GM Shane Terblanche said in a release.
Productivity Up, Fuel Use Down
“Test data shows that the RunWise system is delivering up to 20% incremental fuel savings over traditional CNG trucks and a 10% improvement in productivity,” Terblanche said. “We can anticipate that reduced brake wear and routine maintenance requirements will also contribute to the value of these clean energy vehicles.”
Parker Hannifin hydraulic hybrid business development director Tom DeCoster notes that the powerful hydraulic drive more than makes up for any perceived lack of torque from the CNG system.
“At the end of the day they can haul more trash in less time with less fuel with a corresponding reduction in emissions,” he told F&F.
DeCoster notes terrific brake maintenance savings too: “brakes done once in the life of the truck.”
More Fleet Trials Planned
DeCoster says that more trials are planned, with “pent-up demand in California all the way up the coast to Washington.” The CNG hybrid will be tested in the East too, with the calendar for 2014 “pretty much booked.”
“We’ll continue to run it and get customer feedback,” he says.
Initial trials and subsequent initial sales of the Autocar E3 hydraulic hybrid truck were in the Miami area.
“The RunWise Advanced Series Hybrid Drive System improves upon the typical gains achieved by using natural gas as a fuel source, making these refuse trucks the cleanest environmental solution on the road today,” states the company announcement.
“As many municipalities and fleet operators look to convert to CNG, the RunWise system is attractive to those who are under pressure to meet reduced emissions mandates.
“With a million miles of operation and 99% uptime,” Parker says, “RunWise technology has proven effective in consistently providing significant reductions in fuel consumption and emissions resulting in numerous repeat orders, and drivers who appreciate the responsiveness and reduced noise.”
Diesel-Fueled Hydraulic Hybrid Sales Progress
Parker says it will continue to develop the combined vehicle with to commercialize a CNG option for RunWise trucks. The concept for a CNG-fueled hybrid was initially floated by Autocar at the combined WasteCon-American Public Works Association show in Boston in summer 2010 (F&F, August 23, 2010).
Thus far in 2014, Autocar has placed diesel-fueled E3 hydraulic hybrid trucks in
- Orlando, Fla. – five new trucks for a total of nine;
- New Braunfels, Texas – three new trucks for a total of six;
- Marin Sanitary, Marin County, Calif. – one new truck for a total of two; Santa Cruz, Calif. – five new trucks for a total of six;
- Tacoma, Wash – eight new trucks for a total of nine;
- Oberlin, Ohio – three new trucks; and
- Loveland, Colo. – six new trucks.
