Cummins Announces 5.0L V8 Diesel Engine for North America
Cummins Inc. (NYSE: CMI) has 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.
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. Together, the OEM and Cummins complete a rigorous installation quality assessment, ensuring that the highest-quality product is delivered to our mutual customers.
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.
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. 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 lb-ft (759 N•m), and quick throttle response. Ratings from 200 (149 kW) to 275 horsepower (205 kW) 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™ 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 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.
