FPT Presents New HI-eSCR2 Aftertreatment System to Meet Stage V

At bauma 2016, FPT introduced the next generation of its HI-eSCR aftertreatment system which will enable compliance with the impending Stage V emissions regulations.

Alongside FPT Industrial’s comprehensive range of engines, the world-leading manufacturer and supplier showcased its patented second generation HI-eSCR aftertreatment Stage V solution at the 31st edition of bauma in Munich, Germany, April 11-17, 2016.

The extensive range of off-the-shelf powertrain solutions for construction applications, from mini excavators to wheel loaders, covers from 2.2-20 L and can satisfy all customer requests. If this is not enough, FPT has the capability, with its seven R&D centers and over 900 engineers around the world, to develop customized products, matching even the most demanding request from an OEM.

To comply with Stage V emissions standards, all engines above 4 L will use HI-eSCR2, the second generation of FPT Industrial’s renowned and patented High Efficiency Selective Catalytic Reduction (HI-eSCR) aftertreatment technology. FPT Industrial confirms its long-term SCR-only strategy in order to achieve uprated standards. It’s one of the few manufacturers to retain an Exhaust Gas Recirculation (EGR) and active regeneration free solution, maintaining the competitive advantages achieved in Stage IV/Tier 4 Final, such as best in class in fuel economy and best in class in power and torque density.

In order to meet Stage V, both particle mass and particle count requirements, the second generation HI-eSCR system has an integrated particle filter on the SCR, which makes it an extremely compact solution. When considering the engine, its cooling and aftertreatment system, FPT’s solution is 10% smaller than the competitor average (considering 6 L, 6-cylinder engine competitors).

On top of this, FPT’s flexible solution, with up to 20 different layouts available for each power node, avoids additional redesign efforts from the vehicle manufacturer, as its predecessor. The newly integrated particle filter does not require active regeneration and the engine is best in class in fluid consumption, using around 3% less versus average competitors using EGR and active regeneration. 

Engines on display

FPT Industrial’s smallest Tier 4 Final engine, the 3-cylinder, 2.2 L R22, is the most compact engine in the low displacement segment, especially suited for applications such as mini excavators and pavers, offering high performance up to 52 kW and low maintenance. Featuring Common Rail fuel injection and a turbocharger with after-cooler and waste gate, this powertrain solution has service intervals of up to 600 hours and meets Tier 4 Final/Stage IIIB emissions regulations with the aid of a maintenance-free aftertreatment solution, adopting a combination of Diesel Oxidation Catalyst (DOC) and Partial Flow Filter (PFF), contained in an integrated converter.

Alongside the low displacement R22, FPT Industrial showcased its N45, a 4-cylinder, 4.5 L engine delivering up to 129 kW, part of the NEF Series, recognized for offering high-performance, reliable, cost-effective and compact solutions for applications such as telehandlers and wheeled excavators.

Also from the NEF Series, the N67 was on display. Ideal for applications such as wheel loaders, crawler excavators and graders, this 6.7 L, 6-cylinder unit has a maximum power output of 210 kW.

At the high end of the scale, the 6-cylinder, 16 L Cursor 16 delivers 18 L performance in a 13 L compact package with best in class power and torque density, performance and service intervals. With up to 630 kW, this engine is developed for applications such as large excavators and dumpers. 

To comply with Tier 4 Final/Stage IV emissions standards, all engines above 4 L, including the Cursor 16, use the patented HI-eSCR system.

Developed ahead of Euro VI and Tier 4 Final emissions regulations implemented in 2014, FPT Industrial’s patented HI-eSCR aftertreatment solution maximizes combustion efficiency in order to reduce particulate matter production and meet legislation. The solution uses clean air rather than EGR before the aftertreatment HI-eSCR converts NOx to diatomic nitrogen and water, and does not need a Diesel Particulate Filter (DPF).

To further support customers with Tier 4 Final/Stage IV emissions regulations, the HI-eSCR aftertreatment system is extremely flexible in terms of installation. Resulting from the absence of EGR, FPT Industrial’s solutions do not require OEMs to change the existing cooling packs used in Tier 4 Interim. This saves costs, weight and space and is in direct contrast to Tier 4 Final solutions adopting EGR.

In view of the future Stage V emissions regulations, FPT also presents the F34, its 3.4 L, 4-cylinder engine ideal for applications such as telehandlers, backhoe loaders and pavers.

All these engines and more are also available for power generation applications, in versions including bare engines, G-Drives, soundproof and open gensets. FPT Industrial has recently extended its range of these solutions to now support applications from 31-582 kW with the launch of two new G-Drives (S8000 and C16) at Middle East Electricity 2016.
