Cummins announces five-liter diesel

Cummins Inc (NYSE: CMI) will be offering the ISV5.0, a new 5-liter V8 diesel engine designed to power light- and medium-duty vehicles such as pickup-and-delivery trucks, school buses, and motorhomes.

"Cummins ISV5.0 creates new opportunities for our OEM customers as a compact and lightweight engine that delivers best-in-class fuel efficiency and total cost of ownership," said Dave Crompton, Cummins vice-president and general manager of the company’s engine business. "Many of our customers have asked for a Cummins alternative for gasoline or other small displacement automotive diesel engines. The ISV5.0 represents the next dimension in fuel economy and performance as Cummins continues to broaden our on-highway product line."

The ISV5.0 has been designed to easily fit where a comparable V8 or V10 gasoline engine was previously installed. Multiple front-end accessory drive options handle the common automotive accessories required by a wide spectrum of applications, including the alternator, air compressor, A/C compressor and hydraulic pump. These available options, coupled with Cummins integration expertise, minimize OEM engineering time and vehicle retooling costs, the company says.

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 contribute to the excellent noise, vibration and harshness (NVH) characteristics achieved by the ISV5.0.

With multiple injection events driven by integrated electronic controls, the HPCR fuel system, along with Cummins VGT(TM) variable-geometry turbocharger, combine to produce peak torque of 560 lb-ft.  Ratings from 200 to 275 horsepower are available.

In cold weather, the advanced ceramic glow plug system significantly reduces start time and electrical current draw, reducing vehicle charging system requirements. The ceramic glow plugs are designed to last the life of the engine, with no maintenance.

A two-stage fuel filter system for the ISV5.0 features the latest NanoNet(TM) media from Cummins Filtration, to ensure that the HPCR 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.

Cummins Filtration's expertise also extends to a high-efficiency coalescing filter, for eliminating crankcase hydrocarbon emissions and oil mist, further adding to the clean-engine credentials of the ISV5.0.

Proven air handling and emissions control technology draws upon Cummins extensive emissions technology expertise. Cummins VGT Turbocharger, cooled Exhaust Gas Recirculation (EGR) and Cummins Emission Solutions Aftertreatment System, featuring a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR), result in near-zero oxides of nitrogen (NOx) and particulate matter (PM) emissions while delivering better performance and fuel economy.

"Cummins has integrated the latest technologies in the ISV5.0 to deliver performance, fuel efficiency and durability in a highly sociable package. 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."

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.
