A new Cummins diesel V8 engine will be powering some 2015 pickup trucks.
Cummins Inc. announced 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.
“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 – 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.”
Cummins said 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.
Cummins also said the ISV5.0 brings together a compacted graphite iron (CGI) cylinder block, forged steel crankshaft, high-strength aluminum alloy heads, and composite valve covers. These features, along with dual overhead camshafts, contribute to what the company considers excellent noise, vibration and harshness (NVH) characteristics achieved by the ISV5.0.
High injection pressures from 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. With multiple injection events driven by integrated electronic controls, the HPCR fuel system, along with Cummins VGT Variable Geometry Turbocharger, contributes to a peak torque of 560 pound-foot; the V8 will be available in versions ranging from 200 to 275 horsepower.
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. NanoNet’s unique construction provides lower fuel-flow restriction, and traps greater than 99 percent of all particles as small as 4 microns.
Cummins also included a high-efficiency coalescing filter, for eliminating crankcase hydrocarbon emissions and oil mist.
According to Cummins, its 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.”
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.
Only one OEM pickup truck is currently available with a Cummins diesel engine, the Ram pickup (previously Dodge Ram). It is too early to know if this V8 will replace the current Cummins inline 6-cylinder 6.7L Turbo Diesel, which delivers 385 horsepower and 850 pound-foot of torque.
Cummins has not yet revealed which OEM will use this engine in their pickup truck.
