Parker-Autocar-Cummins Westport Collaborate on Prototype
Parker Hannifin is supplying the RunWise series hydraulic hybrid driveline and Cummins Westport the brand new 8.9-liter ISL G engine for a compressed natural gas-fueled version of the Autocar E3 refuse truck, now in prototype stage.
Customers in states including Florida, Texas and California are enjoying substantial fuel savings with upwards of 100 of the now commercial RunWise-powered diesel trucks, says Tom DeCoster. With CNG fuel they can expect even lower operating costs and reduced greenhouse gas emissions.
How much fuel does RunWise save? As a percentage of gallons burned, “Our national fleet average is in the 40s,” DeCoster told F&F. “RunWise is fuel-agnostic,” he adds, noting that operators can expect relatively quick payback – between two and five years – on a per-truck price premium of about $99,000.
Stopping Brake Jobs
Besides saving fuel, RunWise virtually eliminates brake replacements reducing brake-job frequency from two or three times a year to once in six or even seven years, DeCoster says: “The only time the brakes are on is under a mile an hour and in an ABS event.”
RunWise cut its teeth with fleets in southern Florida (F&F, November 27, 2012 and previous reports). Now Orlando has placed two large orders and is readying a third. Also to be announced soon is a RunWise Autocar E3 sale in Loveland, Colo., DeCoster says.
“Word of mouth is positive and it’s spreading,” he says. “Customer demand is strong.”
Tacoma, Wash. is likely to see first placement of the CNG variant.
Package Delivery Is on Its Way
In addition to the heavy drivetrain for garbage trucks, Parker Hannifin has a smaller version of the RunWise (F&F, March 8) series hydraulic hybrid drive in pre-production trials for package delivery, DeCoster says – some 48 vehicles being put through their paces by fleets including FedEx and UPS.
“The fuel economy improvements on the parcel delivery side average between 35 and 50%,” DeCoster says, noting that the delivery sector applies miles per gallon as its key mileage metric.
