2016 Nissan Titan XD Turbocharger a new design in V8 pickup diesels
When the covers were pulled off the 2016 Nissan TITAN XD full-size pickup at the 2015 North American International Auto Show in January, it was really two debuts in one with the all-new Cummins 5.0L V8 Turbo Diesel engine being shown for the first time too.
The Cummins 5.0L V8 Turbo Diesel in the upcoming 2016 Nissan TITAN XD features a unique Cummins M² Two-Stage Turbocharger is configured to work well at both low and high engine speeds.
The series sequential turbocharging system, involving two differently sized turbochargers, effectively provides a small turbocharger for low air flow requirements and a large turbo for high air flow.
The small turbo provides the advantage of 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.
In order to control the air flow between the two turbochargers, the new M² system from Cummins Turbo Technologies uses a patented rotary valve to open ports that perform the bypass or waste-gate functionality and provide exhaust after-treatment thermal management.
