Stage V

Thanks to a EGR-free architecture, latest generation Common Rail injection,WG turbocharger and redesigned hardware, NEF engines ensure optimal combustion efficiency resulting in low fuel consumption and high power density. 

Performance increase compared to Stage IV / Tier 4Final with same engine displacement and no layout changes: up to 260 kW on N67 (+13%), ensuring torque and power density leadership (15% higher than competitors average in 6 lt range) Moreover, VGT turbocharger allows for prompt engine response for highly demaning missions in Agricultural and Construction applications.

Best in class service interval up to 1200 hours thanks to new high capacity filters with clogging sensor. 

Maintenance-free HI-eSCR2 for low running costs over lifecycle (no need to replace aftertreatment) Optimized fluid efficiency with EGR-free combustion and, where adopted, VGT turbocharger. 

No need to stop equipment for un-necessary parked regenerations. 

Reduced oil consumption thanks to new piston rings design and advanced machining process.

Produced in more than 1.7 million units since 2001, ensuring robustness and durability. More than 25 years experience SCR technology with exclusive patented solutions. 

Proven system reliability thanks to lean design with EGR-free and single stage turbocharging solution.

Both NEF engines and Hi-eSCR2 system are offered in a compact and lightweight design to reduce packaging and facilitate installation on vehicle, offering a wide range of aftertreatment layouts for customized solutions. 

EGR-free technology reduces cooling power needs, further simplifying OEMs’ installation with same cooling requirements across all emission stages.
