Technological excellence and product innovation are at the core of FPT Industrial’s mission. We have focused our R&D activities in order to become the innovation leader in the industrial powertrain field and a go-to provider of the most advanced solutions with a low environmental footprint. Compliance with emission standards comes with minimal impact on vehicle architecture. HI-eSCR is a breakthrough technology bringing vast performance and efficiency benefits. This FPT patent makes the most of a 25-year, 1-millionunit experience. To comply with future Stage V standards, the second generation HI-eSCR2 builds competitive advantages, including best-in-class performance and low running costs.

During the combustion process, the chemical energy of the fuel is converted into mechanical energy. Because of the chemistry of combustion, several pollutants are produced, of which the most harmful are Nitrogen Oxides (NOx) and Particulate Matter (PM). Since 2011, when Tier4 Interim/Stage IIIB came into force, many efforts have been made to reduce such pollutants damaging the environment. Tier4 Final/Stage IV regulation, introduced in 2014, implied a further significant reduction of NOx (-80% Vs. Tier4 Interim/Stage IIIB levels) while PM was not affected by further reductions. Stage V, a new regulatory step, will be introduced in Europe starting from 2019/2020 depending on engine power level, further tightening the limits on PM emissions: admitted PM quantity will be reduced by 40% compared to Stage IV and a new limit will be introduced on the number of emitted particles (Particle Number Limit, PN). In addition, Stage V regulation will involve power ranges currently with lighter or no legislation at all in Europe (power ranges below 37kW or above 560kW).

FPT's Hi-eSCR 2

Stage V To maintain the advantages of the unique and unbeaten HI-eSCR 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, applicable for engines above 56kW and below 560kW, where different emission limits apply, will maintain the same after-treatment dimension of the current Tier4 Final / Stage IV applications, requiring no machine redesign nor layout changes for easier upgrade to next emission level. Thanks to optimized combustion, leadership on performance and fuel efficiency is confirmed, while maintenance free aftertreatment and no need for parked regeneration ensure low running costs avoiding unplanned downtime.

Advantages

• High performance for increased vehicle productivity.
• No additional complexity and lean design for easier installation and maximum reliability.
• Low operating costs thanks to high efficiency and long service intervals.

By way of continuous technical advantages our state of the art engine range allows our customers to have class leading features, such as minimized total cost of ownership and outstanding performance. Key to the optimization of engine efficiency is EGR-free combustion on NEF and Cursor engine families, together with high cylinder pressure and high injection pressures: engines adopting the latest generation of Common Rail system feature peak nozzle pressures of up to 2200 bar. To achieve these targets, crankcase and cylinder head design has been improved to ensure increased structural stiffness. An Electronic Control Unit manages engine parameters and guarantees an accurate control of the after treatment system. Extended service interval, together with a maintenance-free after-treatment solution reduce running cost for end users.

Main Components

The whole system is fitted with a network of integrated sensors to control temperature, pressure and NOx levels. Exhaust gas flow coming from the engine enters the DOC, where NO is oxidised to NO2, in order to maximize SCR catalyst’s efficiency conversion. The ECU (Engine Control Unit), the brain behind the HI-eSCR 2 system, checks, through integrated sensors network, the amount of Water-Urea (DEF/AdBlue) solution to be injected in the exhaust pipe. To increase the durability of the injector, Dosing Module is cooled by the engine coolant. The HI-eSCR 2 after-treatment system adopts a fiLering device on its SCR catalyst. At the same time as trapping and oxidizing the Particulate Matter, the catalyst converts NOx into Nitrogen (N2) and water (H2O) thanks to the chemical reaction of Ammonia (NH3) generated from DEF/Adblue. In the end, the integrated CUC eliminates the remaining Ammonia (NH3). The result is a reduction of NOx superior to 95% and the PM levels within Stage V emission limits.

Patents

Cursor Designed to Go Beyond

Developed for the most demanding heavy duty needs, the Cursor series provides robust design for highly intensive missions in a wide range of cons- truction applications from 175 to 570 kW. First launched in 1998, the Cursor range has gone through continuous improvements to keep pace with growing market requirements in performance and efficiency, while complying with stricter emission regulations and always offering innovative technical contents, such as variable-geometry turbochargers, high-pressure common rail injection, new materials and breakthrough after-treatment technologies.

All Cursor engines share 6 cylinder architecture and EGR-free technology, ensuring optimal engine output with highly efficient combustion, resulting in effective performance and low cooling requirements, unchanged from Stage IIIA to Stage V for smart synergies across machine layouts. Moreover, all engines meet Stage V regulation with maintenance-free HI-eSCR2 system, the latest generation of FPT’s longstanding experience in after-treatment technology, proven by more than 1 million systems sold to date. No need of filter replacement over lifecycle, together with up to 600 hours oil change interval, minimizes running costs.

Cursor9, with 8,7 lt displacement, is a compact and yet powerful solution in 175 to 330kW range, adopting a 1800 bar common rail system, fixed or variable-geometry turbocharger resulting in prompt engine response and leading power density (up to 7% better than market average)

With 11,1 and 12,9 lt respectively, Cursor 11 and Cursor 13 features heavy-duty 2200 bar common rail system and newly designed engine hardware for maximized robustness and durability. With single and high-performance two stage-turbo on Cursor13, these engines cover range from 300 to 515kW peak.

Awarded as Diesel of the Year in 2014, Cursor16 is the latest addition to the Cursor range, with 15,9 lt displacement and up to 570kW delivering 18 lt-like performance in a 13 lt package, with leading power-to-weight ratio (0,5 hp/kg). 2200 bar common rail system, innovative ball-bearing turbocharger, high-resistance cylinder head in compacted graphite iron (CGI) and more than 20.000 hours of bench-test specifically dedicated to off-road missions, make the Cursor16 a strong, reliable yet compact solution.
