Maintaining the advantages of the unique & unbeaten HI-eSC​R technology FPT Industrial will integrate a maintenance-free ​​filtering device on its SCR catalyst, thus allowing to comply with tightened limits on PM emissions within a compact package. The second generation HI-eSCR 2 will maintain the same after-treatment dimension of the current Tier 4B/Stage IV applications,​ requiring no m​​achine redesign nor layout changes for easier upgrade to next emission level; thanks to the EGR-free combustion, performance and operating costs are optimized confirming the FPT Industrial’s competitive advantage.​

HIGH PRODUCTIVITY & ​​​​​SAFETY​​​​
Best in class power & torque density. Lowest after treatment temperature: no need of heat protection against active regeneration peak temperatures. Maximising uptime: no need to stop equipment for regeneration.


LOW OPERATING COSTS
Best in class fluid consumption cost*. After treatment system for life: based on particle number reduction experience with over 3.5 billion hours in field.


EASY OF INSTALLATION
Same engine cooling package from stage IIIa to stage v. Smallest overall packaging**. Multiple off-the-shelf configurations available: more than 20 different layouts available for each power node.​


* compared to competitor average using EGR & active regeneration 
** when considering a packaging including cooling system, engine & after-treatment system
