Thanks to FPT’s pioneering EGR free combustion and exclusive, patented HI-eSCR2 aftertreament technology, NEF series represents the productivity benchmark in mid-range applications, with further enhancements in performance and efficiency with newly designed Stage V engines.

Maintaining the same engine dimensions and layout of previous versions, cylinder head, pistons and turbochargers have been redesigned for performance increase.

66 – 150
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 150 kW on N45 (+15%).

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. 

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