HI-eSCR and Cursor 9 CNG are the keywords of leading powertrain supplier FPT Industrial’s presence at the IAA Commercial Vehicles in Hannover, Germany, taking place September 22-29, 2016. With a vast range of powertrain solutions for the commercial vehicle industry, FPT Industrial’s excellence is a result of almost 150 years of continuous innovations and cooperation with truck and bus manufacturers.
Present with its own private lounge and through its CNH Industrial Group’s sister company Iveco (stand A01 Hall 16), FPT is showcasing the last releases of its most representative engine from its alternative fuel lineup, its class-leading 9 L CNG engine and its TCO leader Cursor 11.
FPT Industrial is a pioneer in Natural Gas solutions for on-road and off-road market
FPT Industrial, with over 25 years of experience and more than 30,000 CNG engines sold, has always been a pioneer in the development of natural gas engines and boosts the broadest engine range on the market for on-road use, able to satisfy requests for both commercial vehicle and bus applications. FPT's extensive offer of natural gas engines includes the F1C, the NEF6 and the last release of Cursor 9 CNG.
Cursor 9 CNG, the most powerful 9 liter CNG engine
Launched by FPT at the Beijing Bus and Truck Show in May, this 6-cylinder CNG engine is the ideal solution for applications such as heavy haulage, garbage collection, city and intercity transportation. Powered by natural gas in its compressed (CNG), liquefied (LNG) or renewable form (bio-methane), it offers power up to 400 hp at 2,000 rpm, torque up to 1,700 Nm at 1,200 rpm while at the same time having emissions lower than Euro VI. Furthermore, Cursor 9 has a ratio of 10 hp per ton of load, which is in line with commercial long-distance standards.
Equaling the performance of FPT Industrial’s Best in Class Cursor 9 diesel version, it is the only alternatively fueled 8.7 L that can compete with its diesel counterpart without compromise. Compared to diesel, the CO2 emissions of natural gas powered vehicles are significantly less and can be close to zero by using bio-methane.
To comply with Euro VI, the Cursor 9 CNG does not need Exhaust Gas Recirculation (EGR) or Selective Catalytic Reduction (SCR), but relies on a simple three-way catalyst. A compact catalytic converter, located at the end of the exhaust, with an integrated structure plated with three precious metals. Where the Platinum and Palladium convert CO and HC into CO2 and H2O, the Rodium converts NOx into nitrogen gas (N2).
Compared to the Cursor 9 diesel, the new engine has a Ni-Resist cast-iron exhaust manifold and water cooled wastegate turbocharger, increasing reliability. This is further supported by new piston rings to increase the oil service intervals by 25% versus the Cursor 8 CNG, arriving at best in class for scheduled maintenance. To increase driver comfort and thus performance of the final product the Cursor 9 CNG is the first alternatively fueled heavy-duty engine that can be coupled to an automated robotized transmission. Furthermore, the truck equipped with the new engine makes less noise than the average vacuum cleaner allowing for inner-city delivery at less than 72 dB(A).
The Cursor 9 CNG uses stoichiometric combustion to generate its power. Since 1995, when FPT Industrial started developing CNG solutions for industrial applications, it has been company’s chosen technology, proven to be the only viable and cost-efficient solution available today to meet Euro VI emission limits.
HI-eSCR, the innovative EGR free and regeneration free High Efficiency Euro VI Step C solution
To comply with Euro VI Step C, the NEF and Cursor Series engines are equipped with FPT Industrial’s innovative High Efficiency SCR (HI-eSCR) technology, which has NOx conversion efficiency higher than 95%. HI-eSCR represents the latest breakthrough in SCR, which was pioneered by FPT Industrial at its Research & Development Center in Arbon, Switzerland. Since 2005, over 650,000 units have been produced and are in operation in various applications like trucks, agricultural and construction equipment.
FPT's engines equipped with HI-eSCR introduce a wide range of advantages both for customers and for OEMs. With a focus on maximizing combustion efficiency and reducing particulate matter production to meet regulations, the HI-eSCR enabler avoids the use of high rate EGR to reduce NOx. It means no efficiency loss, resulting in more power and torque density and lower specific fuel consumption. Regeneration free: at the same time, with no DPF active regeneration, no additional device to burn soot increases reliability and reduces thermal and mechanical system stress allowing best in class DPF service intervals. HI-eSCR requires also no DPF forced/parked regeneration: no vehicle stops, no temperature increase and no additional fuel consumption, assuring no downtime, top safety in all working condition and best in class TCO. Furthermore, HI-eSCR needs no additional cooling requirements and is easy to install due to small packaging of the ATS solutions.
Cursor 11, the TCO leader
Also present in the Iveco stand at IAA Commercial Vehicles 2016 FPT’s 11.1 L Cursor 11. Cursor 11 represents one of the examples of FPT’s continuous research and development activities, adopting the most advanced technologies, such as a last generation heavy-duty Common Rail injection system and electronically controlled variable geometry turbocharger. It offers power outputs from 309- 353 kW and torque from 2,000-2,300 Nm.
The Cursor 11 showcased in the new Iveco Stralis at IAA is a 460 hp, Euro VI Step C, clutch air compressor, smart alternator and has a variable geometry steering pump, enabling fuel consumption reduction up to 3%.
Cursor 11 is available also in an extremely low rate EGR version (Smart EGR) which is used to optimize combustion, resulting in significant fuel savings on long distances. This solution harnesses a small amount of exhaust re-circulation – just 8% – to allow an earlier start of injection. The result is greater fuel economy while maintaining the high 97% tailpipe NOx conversion delivered by the HI-eSCR system and all the benefits of this technology: regeneration free, no impact on radiator size, no extra maintenance, and the longest service intervals bringing a further fuel and TCO reduction to the customer.
