Nissan is offering a 5.0-liter Cummins turbo diesel with its 2016 Titan pickup for the first time that will give work truck buyers greater capability for towing and payload, Nissan has announced.
Nissan introduced its redesigned next-gen Titan at the North American International Auto Show in Detroit.
The new 5.0-liter V-8 turbo diesel, from the Cummins ISV family, is rated to produce 310 hp and 555 lb.-ft. of torque. It contains 70 percent of the parts offered on the commercial variant of the engine. The turbo diesel will be offered on the Titan XD model.
Nissan has been working with Cummins since 2007 in a partnership to possibly introduce a diesel engine for the Titan. Production will begin later in 2015.
The turbo diesel uses a compacted graphite iron cylinder block, forged steel crankshaft, high-strength aluminum allow heads, and composite valve covers to achieve a durable, lightweight package. The engine uses dual overhead camshafts.
The Cummins M2 two-stage turbocharger has been configured to work well at low and high engine speeds.
The series sequential turbocharging system uses two differently sized turbochargers, including a small turbocharger for low air flow requirements and a large turbo for high air flow. The small turbo provides good transient response due to its low inertia, and the large turbo maintains power at higher engine speeds. This helps eliminates turbo lag, providing a continuous delivery of peak torque through the RPM range, according to Nissan.
In order to control the air flow between the two turbo chargers, the new M2 system uses a rotary valve to open ports that perform the bypass or waste-gate functionality and provide exhaust after-treatment thermal management.
High injection pressures from the 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, Nissan announced.
