Cummins 2.8 L diesel revealed in Nissan concept truck

11 February 2014

Cummins and Nissan unveiled a concept Nissan Frontier Diesel Runner pickup truck at the Chicago Auto Show. The vehicle is powered by a concept 2.8 L turbo diesel engine—developed at the Cummins Technical Center in Columbus, IN—that produces approximately 200 hp and over 350 lb-ft of torque. This concept 2.8 L has been matched with a Nissan Frontier Desert Runner 4x2 in a project to evaluate the viability of this package for North America.

Cummins has been supplying diesel pickup truck engines for a number of years. The 5.0 L V8 Turbo Diesel for the next-generation Nissan Titan and the ISF2.8, used in markets outside the United States, are the latest production engines for the pickup truck market.

The concept Nissan Frontier Diesel Runner – Powered by Cummins on display at the Chicago Auto Show was one of two trucks specially repowered by Cummins to demonstrate the latest in diesel capabilities.

In addition to the concept 2.8 L engine and the new 5.0 L V8 Turbo Diesel for the next-generation Titan, Cummins has been developing a 2.8 L pickup truck diesel targeting US EPA Tier 2 Bin 2 (T2B2) emissions. The development—conducted in cooperation with Johnson Matthey and Nissan—is a part of the US Department of Energy (DOE) ATLAS research project.

A number of advanced emission technologies have been considered for the ATLAS T2B2 engine, such as a Johnson Matthey’s cold start concept (dCSC™) that adsorbs HC and NOx after a cold start and releases them after the other aftertreatment components have warmed up sufficiency to achieve high conversion efficiency. The dCSC™ would be followed by a close-coupled DPF coated with an SCR catalyst (SCRF®) and an underfloor SCR system. An Amminex direct ammonia system has been considered to supply SCR reductant.
