One of the main differences between the ISV5.0 and this Cummins engine is the new Holset M2 Two-Stage Turbo system by Cummins Turbo Technologies that was developed in the U.S. and U.K. specifically for the Titan XD. The compound turbo setup is mounted in the valley of the V8 engine and utilizes a small and large turbo in series. Helping them work in tandem is an electronically actuated wastegate system with a patented “Rotary Turbine Control” valve that operates the opening of ports during four main operating modes:
1. Low Pressure Single-Stage Turbo Mode
2. High Pressure Two-Stage Turbo Mode
3. Wastegate Mode (maximum engine power output)
4. Regeneration Mode
This system is designed to provide minimal turbo lag and good responsiveness in all driving situations while maximizing the effectiveness of the emissions controls for clean operation along with good fuel economy.
As for construction, The Nissan Cummins 5.0 L V8 uses a block made from compacted graphite iron with a forged steel crankshaft and aluminum pistons. The heads are made from aluminum alloy and have composite valve covers to keep weight low and reduce noise. The dual overhead camshafts that rest inside the covers are used to operate four valves per cylinder. Ceramic glow plugs by Bosch are designed for quick start times and to last the lifetime of the engine without any maintenance. Bosch also provides the CP4.2 high-pressure common-rail fuel system with piezo-controlled injectors. A two-stage fuel filter system uses NanoNet media by Cummins Filtration to provide high flow rates while filtering out 99 percent of particles 4-microns and larger. All of this technology along with the M2 turbo system combines to give the all-new diesel-powered Nissan Titan XD a towing capacity of 12000 pounds and a maximum payload rating of 2000 pounds.
