Maintaining the advantages of the unique & unbeaten HI-eSC​R technology FPT Industrial integrates 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 maintains 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.​
