The ISV5.0L 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.
Cummins Inc. unveiled 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.
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, according to the company.

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., and quick throttle response. Ratings from 200 to 275 HP are available.
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 reported.
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.
