The new IVECO Cursor 13 NP engine, engineered by FPT Industrial, was specifically developed for long-haul international transport. The most powerful pure gas engine on the market, it delivers the performance needed for the most demanding missions. The enhanced combustion process of the 12.9-litre displacement engine ensure the best fuel efficiency in long distance missions. The high fuel-flow gas injectors, fuel rail, pistons and turbo are designed to deliver high power output and torque. The durability and maintenance intervals have been extended to ensure the right performance with no compromise on uptime.
This result was achieved by applying spark-ignition stoichiometric combustion to natural gas. It is a “single fuel” solution that enables the IVECO Cursor 13 NP to run on 100% natural gas. The exhaust after-treatment is based on a compact and light 3-way catalyst that requires no regeneration or additives, bringing obvious benefits in terms of package and payload, as well as in reduced downtime. The IVECO Cursor 13 NP offers the added advantage of low noise and vibration, as stoichiometric combustion runs at 12:1 compression ratio (well below the 17:1 ratio of the Diesel cycle) and is therefore intrinsically quieter.
The IVECO Cursor 13 NP engine is protected by two patents: the first, for which patent protection is in progress, is the FPT Industrial proprietary knock control that makes it possible to increase the performance, enables the widest fuel compatibility, and protects engine and 3-way catalyst from misfiring.
The second one is FPT Industrial’s proprietary reactive air-flow control management system, a new stoichiometric ratio control logic that is applied during gearshifts. This ensures a continuous torque delivery during AMT gearshifting, which enables maximised performance and the fastest gearshift. FPT Industrial has applied for patent registration for this system.
The Stralis NP 460 is the first natural gas truck with the latest-generation automated transmission, the new 12-speed HI-TRONIX automated gearbox which offers the most advanced technology in its category, with 99.7% efficiency, exceptional durability, best-in-class gear spread of 16.7 and torque-to-weight ratio. This new transmission reduces shifting time by 10% compared to the previous model, and offers additional functionalities such as rocking function, four reverse gears and a new offer of PTOs. The HI-TRONIX comes with standard integrated hydraulic retarder and hill-holder function for driver and load safety.
The air-flow control management system ensures the perfect integration of engine and gearbox in the Stralis NP 460.
The Stralis NP 460 delivers fuel economy on all missions ranging from medium-distance regional routes all the way to long-haul international transport. In addition to the outstanding fuel efficiency of the engine, it features fuel-saving solutions such as the DRIVING STYLE EVALUATION to monitor and improve driving behaviour, the ECOSWITCH speed and torque limiter, ECOFLEET for the most efficient shifting strategy, the optimised rear axle ratio, the low-rolling resistance eco-tyres and IVECO's Fuel Consultancy Services. It also introduces the HI-CRUISE integrated drive system that includes GPS-based systems such as predictive cruise control and gearshifting, and further enhances the eco-roll function.
