Cummins Inc. announced it will begin producing the ISV5.0, a new 5-liter V8 diesel engine designed to power pickup-and-delivery vehicles, other light- and medium-duty trucks, school buses and motorhomes.
The ISV5.0 extends Cummins’ range of clean-diesel engines for North American vehicles, and features industry-leading technology that delivers performance and a low total cost of ownership to customers.
“The ISV5.0 represents the next dimension in fuel economy and performance as Cummins continues to broaden our on-highway product line,” said Dave Crompton, Cummins Vice President and General Manager – Engine Business.
The ISV5.0 has been designed to easily fit where a comparable V8 or V10 gasoline engine was previously installed. The ISV5.0 brings together a compacted graphite iron (CGI) cylinder block, forged steel crankshaft, high-strength aluminum alloy heads, and composite valve covers to offer maximum durability in a lightweight package. These features, along with dual overhead camshafts, also reduce noise, vibration and harshness.
Leading engine technology produces better fuel efficiency and reduced emissions. With multiple injection events driven by integrated electronic controls, the ISV5.0’s fuel system and Cummins VGT™ Variable Geometry Turbocharger contribute to a very impressive peak torque of 560 lb-ft and quick throttle response. Ratings from 200 (149 kW) to 275 horsepower (205 kW) are available.
A two-stage fuel filter system for the ISV5.0 features the latest NanoNet™ media from Cummins Filtration, to ensure that the fuel system is fully protected against fuel contamination. NanoNet’s unique construction provides lower fuel-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 extends to a high-efficiency coalescing filter to eliminate crankcase hydrocarbon emissions and oil mist, further adding to the clean-engine credentials of the ISV5.0.
The engine’s air handling and emissions control technology draws upon Cummins’ extensive expertise in emissions technology. The Company’s VGT Turbocharger, cooled Exhaust Gas Recirculation (EGR) and Cummins Emission Solutions’ Aftertreatment System, featuring a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR), reduce the emission of oxides of nitrogen (NOx) and particulate matter (PM) to near-zero levels while delivering better performance and fuel economy.
“Every day, drivers will appreciate the smooth, quiet operation of the ISV5.0,” said Jim Katzenmeyer, Executive Engineer – V8 Program. “In addition, the fuel savings offered by the ISV5.0 result in fewer greenhouse gas emissions — a great environmental benefit.”
The Cummins ISV5.0 will serve customers in the United States and Canada, and will be certified to the near-zero NOx and PM emissions levels required by the U.S. Environmental Protection Agency (EPA). At launch, it will also meet greenhouse gas (GHG) requirements through 2016, and 2015 Air Resources Board (ARB) standards, including on-board diagnostics.
The ISV5.0, along with the 5.0L V8 Turbo Diesel for pickup trucks, will be manufactured at the Columbus Engine Plant. Production of the ISV5.0 will start during the fourth quarter of 2014.
“Our customers want the ISV5.0 engine to come with the world-class service network and customer support that Cummins already provides to them,” said Jeff Jones, Cummins Vice President – North American Engine Business. “The support of this engine will easily be integrated into Cummins distributors and authorized dealer shops, and into customer operations with fleets that are running the broad range of dependable Cummins power.”
