Cummins Develops Lightweight 5.0L V8 Diesel
Cummins Inc. announced Friday (Oct. 4) 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,” Dave Crompton, Cummins vice president and general manager – engine business, said in a statement. “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 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 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 variable geometry turbocharger (VGT), contributes to a very impressive peak torque of 560 lb-ft and quick throttle response. Ratings from 200 hp to 275 hp are available.
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.
