Cummins announces its "next generation of performance"

Cummins - a global power leader - has announced its new ISV5.0 - a 5L V8 diesel engine designed to power pickup-and-delivery vehicles, as well as light and medium duty trucks, school buses and motorhomes through Class 5.

The ISV5.0 extends Cummins range of clean-diesel engines for North American vehicles, said Dave Crompton, Cummins vice president and general manager - engine business, and features industry-leading technology that delivers performance and a low total cost of ownership to customers.

It is the company's "next generation of performance" in its diesel engine product line, Rich Freeland - vice president, Cummins, and president, engine business, said.

"As a compact and lightweight engine that delivers best-in-class fuel efficiency and total cost of to customers, the ISV5.0 creates new opportunities for our OEM customers," noted Crompton. "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 new engine is the commercial version of the Cummins V8 turbocharged diesel engine developed for the 2015 Nissan Titan pickup truck, according to Mike Taylor - director, Cummins customer engineering and business development.

Easy fit

The ISV5.0 has been designed to easily fit where a comparable V8 or V10 gasoline engine was previously installed, noted Jim Katzenmeyer, Cummins executive engineer - V8 program. 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, he said. "Together, the OEM and Cummins complete a rigorous installation quality assessment, ensuring that the highest-quality product is delivered to our mutual customers."

Features

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, said Katzenmeyer. These features, along with dual overhead camshafts, also contribute to the excellent noise, vibration and harshness (NVH) characteristics achieved by the ISV5.0.

The CGI and aluminum alloy heads are a first for Cummins, he noted. 

"High injection pressures from the latest Bosch High Pressure Common Rail (HPCR) fuel system and piezo fuel injectors provide precise fuel control for optimized in-cylinder combustion, leading to better fuel efficiency and reduced emissions," said Katzenmeyer. "With multiple injection events driven by integrated electronic controls, the HPCR fuel system, along with Cummins VGT Variable Geometry Turbocharger, contributes to a very impressive peak torque of 560 ft/lbs (at1,600 rpm) and quick throttle response."

Ratings from 200 to 275 hp at 3,200 rpm 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 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 media, from Cummins Filtration, to ensure that the HPCR fuel system is fully protected against fuel contamination, said Katzenmeyer. "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, he added

Emissions

"Proven air handling and emissions control technology draws upon Cummins extensive emissions technology expertise," Katzenmeyer said.

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," he said.

"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.

"In addition," Katzenmeyer said, "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.

To market

Cummins plans to begin production of its new ISV5.0 V8 diesel engine in the last quarter of 2014, said Jeff Caldwell - Cummins general manager, global pickup business.

The ISV5.0, along with the 5.0L V8 Turbo Diesel for pickup trucks, will be manufactured at Cummins Engine Plant in Columbus, Ind., on a newly built, dedicated production line.

"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."

Cummins Care is available 24/7/365, free of charge, for all Cummins engines, by calling 1-800-DIESELS (1-800-343-7357).

"Built on Cummins strong commitment to customer support, the Cummins Care team is prepared to answer all operational questions on topics such as fuel and oil specifications and maintenance intervals, and can assist customers with finding the nearest authorized and available service location," he pointed out.

"Customers also have access to the largest and most capable service network in the United States and Canada, with over 3,500 locations.”
