New Euro VI FPT engines, more powerful than ever

FPT Industrial, a market leader in power-train technology, supplies the new Iveco Eurocargo with evolutions of its Tector engines to meet Euro VI emission regulations. The updated and upgraded 4-cylinder Tector 5 and 6-cylinder Tector 7 will replace the previous Tector 4 and Tector 6 engines.

The European benchmark in middleweight goods transport, the Iveco Eurocargo will benefit from increases in engine power, torque and durability, if compared with Euro V versions; furthermore, the engine upgrade also improves user comfort with reduced engine noise and vibration.

Setting the standard in their class, Tector engines offer high-performance, reliable, cost-effective and compact solutions. The displacements of both Tector 5 and Tector 7 engines, respectively 4.5 and 6.7 litres, have been right-sized to ensure better versatility across a variety of applications.


The increased displacement, along with the use of a second-generation Common Rail HD system with maximum pressures of up to 1600 bar, bring advantages both in terms of performance and with regard to torque at low speeds. The new Common Rail system multiple injection, with new nozzles for increased dosing precision and timing control, serves to optimise the combustion process, reducing engine particulate and fuel consumption under full load.


The engine with 4-litre displacement has received a 13% power increase to achieve an output of 210 HP. Torque has been improved by 23% with the new evolution producing 750 Nm at 1,400-1,800 rpm. The performance of the 6 cylinder engine has also been improved, with an increase of up to 320 HP thanks to a 7% power boost, while the torque has been increased by 5%, to reach 1100 Nm at 1250-1900 rpm.


Thanks to engines performance increase, Iveco has been able to redefine its own product offer, minimizing fuel consumption and at the same time extending its range.


The Euro VI's 4 cylinder 210 HP Tector 5 engine replaces the 6 cylinder 220 HP Tector 6 on the Euro V, guaranteeing lower fuel consumption whilst maintaining high performance; the six-cylinder Tector 7 reaches a power of 320 HP, while the previous Tector 6 reached a maximum power of 300 HP.


Despite the increased displacement, the Euro VI engine and the relative exhaust gas after-treatment system produced by FPT Industrial are even lighter compared to those of the engines produced by the main competitors, ensuring a greater vehicle payload compared to the market average.


Both engines feature High Efficiency SCR (HI-eSCR), FPT Industrial’s breakthrough after-treatment system that decreases Nitrogen Oxide (NOx) emissions by more than 95 per cent. The HI-eSCR system is the latest evolution in FPT Industrial SCR technology, and has already been successfully used on more than 350,000 engines.


The SCR-only system utilises clean air to maximise combustion efficiency and minimise Particulate Matter (PM) production without the use of Exhaust Gas Recirculation (EGR), thus minimizing fuel consumption and maximizing performance.


The post-treatment system uses a catalytic converter (SCR) which uses the chemical reaction with the water-urea solution (AdBlue) to convert the nitrogen oxide emissions produced during combustion into nitrogen (N2) and water vapour (H2O).

The absence of both the EGR system and of an active regeneration particulate filter (DPF) also ensures increased engine reliability.

The “SCR-Only” technology sees the introduction of a new integrated approach that is the result of extensive research by FPT Industrial, research that has led to the creation of numerous significant patents for:


           "Closed" control, based on the use of sensors, to ensure accurate information regarding the composition of the exhaust gas at any moment as it passes through the HI-eSCR after-treatment system.

           Adaptive dosing system, thanks to "closed" control technology, to reduce the use of AdBlue.

           Thermally insulated high turbulence mixing, to allow homogeneous hydrolysis of urea and correct distribution in exhaust gas flow.

           Improved thermal management to speed up SCR light-off in the cold part of the emission cycle.


Together with HI-eSCR, the engines also feature an electronically governed Exhaust Flap, which contributes significantly to the meeting of Euro VI emission regulations. The exhaust flap is used to speed up SCR warm up in the cold part of the emission cycle, ensuring the optimum SCR working temperatures and therefore peak NOx reduction.


Engine braking power will also be improved with the introduction of this system, achieving maximum brake power of 100 and 150 kwh in the Tector 5 and Tector 7 respectively.

Service intervals of 80,000 km for the Euro VI engines remain unchanged, compared to the Euro V versions, thanks to new high efficiency multi-layer fuel filters and an oil separation blow-by gas system; while the DPF has service intervals of 300,000 km.


In summary, the HI-eSCR system is the only Euro VI post-treatment system that optimizes consumption, reduces system complexity and maintains the original maintenance requirements of the vehicle.


The HI-eSCR technology was an important factor in winning the “International Truck of the Year 2013” accolade awarded to the Iveco Stralis Hi-Way. The quality of the HI-eSCR technological system has recently received major recognition: TÜV (one of the most respected European technical certification centres) has certified that there is a 2.33% reduction in fuel consumption when using the HI-eSCR system.
