SPECIAL REPORT
£ Cummins Inc. unveiled its new, more compact ISV5.0 V8 diesel engine last month for school bus operators who are looking for better fuel mileage and lower total cost of ownership.
Dave Crompton, Cummins’ vice presi- dent and GM of engines, said the potential for lowered total cost of ownership, not to mention the other bells and whistles, pres- ents new opportunities. “Many of our customers have asked
for a Cummins alternative for gasoline or other small-displacement automotive diesel engines,” he added. “Te ISV5.0 represents the next dimension in fuel economy and performance as Cummins continues to broaden our on-highway product line.” Small bus operators especially will take
NEW KID ON THE BLOCK CUMMINS AIMS FOR HIGHER RESIDUAL VALUE FOR CUSTOMERS WITH UNVEILING OF LIGHTER-WEIGHT, MORE FUEL-FRIENDLY DIESEL V8 OPTION WRITTEN BY RYAN GRAY
Good, more economical things can come
in small packages. Tat is precisely what Cummins is banking on with the unveiling of the ISV5.0 V8 diesel that touts lower total cost of ownership with a less expensive install, increased fuel mileage and a more pleasant on-board experience for drivers and passengers.
Cummins said a CGI cylinder block,
forged steel crankshaft, high-strength aluminum alloy heads, and composite valve covers offer maximum durability in a lightweight package. It also reduces noise, vibration and harshness. “Every day, drivers will appreciate the
smooth, quiet operation of the ISV5.0,” said Jim Katzenmeyer, executive engineer of Cummins’ V8 program. Te North American school bus industry
must wait at least a year before it gets its hands on the new option, which Cummins said can be installed in the same compart- ment space previously reserved for V8 or V10 gasoline engines. And the carbon footprint is less. Te engine features the latest NanoNet media
from Cummins Filtration to ensure the fuel system is fully protected against fuel contamination. Cummins said NanoNet’s unique construction provides lower fu- el-flow restriction and traps greater than 99 percent of all particles as small as 4 microns, smaller than the naked eye can see. Cummins Filtration’s expertise also ex- tends to a high-efficiency coalescing filter to eliminate crankcase hydrocarbon emissions and oil mist, further adding to the clean-en- gine credentials of the ISV5.0. Te Cummins VGT Turbocharger, cooled EGR and an aftertreatment system featuring a DPF and SCR reduces NOx and PM emissions to near-zero levels while delivering better performance and fuel economy. An in-tank dosing module also eliminates coolant lines. At launch, Cummins said the ISV5.0 will
meet greenhouse gas requirements through 2016, and 2015 Air Resources Board (ARB) standards, including on-board diagnostics. Te ISV5.0 also features dual overhead camshafts that Cummins said will improve engine performance.

notice. Ford ended the 6.0L diesel option on its E-450 cutaway chassis in 2010. Since then the only alternative for small school bus customers is to purchase the Chevrolet Express or GM Savana cutaway with diesel or an alternative fuel conversion offered on a Ford. “Te only chassis currently available for
type A school bus body up-fitting are the Chevy/GM CG30 and Ford’s E350 and E450. With no diesel power available in Ford’s chassis, buyers choices were limited by Ford to gasoline or alternative fuel con- version,” commented Robert T. Pudlewski, STN’s technical editor at large and chair of NSTA’s Manufacturer Supplier and Technology committee. “Perhaps the intro- duction of the Cummins 5L diesel, with its suitable torque/horsepower and emission control, might find its way as an option into present or future manufacturers of Type A chassis. We can only wait and see.” Te ISV5.0 fuel system and turbo-
charger touts 200 to 275 horsepower while delivering 520 to 560 pounds per foot of torque. In addition to school buses, it will also be available to the pick-up and delivery, light- and medium-truck and motorhome markets. An Oct. 4 ride and drive event at Cummins’ airfield in Columbus, Ind., located about 45 miles south of Indianap- olis, showcased for members of the press the reduced noise, yet similar power to the ISB6.7. Test vehicles equipped with the ISV5.0 included a school bus loaded with sandbags to replicate a fully loaded route at 31,000 GVWR. Other test vehicles on hand included a delivery van, a work truck and a motorhome.
