Cummins Reveals More Details About New Engine

It wasn't that long ago that it would be using a new Cummins engine in its next-generation full-size Titan pickup truck, presumably a 2015 or 2016 model. At the time we had very few details or images of the V-construction (a first-ever for Cummins) motor other than some preliminary horsepower and torque specifications. Now we have more.

At a recent press conference in its hometown of Columbus, Ind., Cummins offered more details about its new 5.0-liter V-8 ISV motor, called the ISV5.0. Because of its size, Cummins hopes this engine will be popular with the pickup-and-delivery segments, light- and medium-duty commercial trucks, and even downsized school buses and motorhomes. Here are some of the technical highlights of the new turbodiesel.

• Was designed to be similar in size to other gas V-8 or V-10 models
• Uses compacted graphite iron in the engine block
• Has a pair of high-strength aluminum-alloy heads for weight savings
• Offers a pair of thick composite valve covers for strength and quietness
• Employs a dual overhead camshaft strategy with four valves per cylinder
• The Bosch high-pressure common rail system uses sophisticated piezo injectors
• The variable geometry turbocharger design is both simple and efficient
• An all-new advanced ceramic glow plug system is quick and cost effective
• A two-stage fuel system (with dual filters) makes combustion super clean
• The ISV motor uses cooled exhaust gas recirculation, a diesel particulate filter and a selective catalytic reduction setup with a downstream diesel exhaust fluid injection to meet current (and future 2016) emissions standards

Cummins will start production of the new engine at the new Columbus plant by the fourth quarter of 2014, with the engines going into medium-duty bus and truck platforms soon after that. Nissan has not officially announced when the new Titan will debut, and Cummins isn't saying either — nor will either company talk about costs or possible take rates.

Because this engine is likely to have quite a few different applications, Cummins is offering several maximum horsepower and torque ratings to accommodate a wide range of uses. We're expecting the Titan to offer close to 300 horsepower and a minimum of 560 pounds-feet of torque. More information on those fronts is sure to follow.
