EcoBlue


New Holland is launching it first Tier-4B-compliant tractors in 2014. In line with our long-established roadmap, all high-horsepower tractors, T7 Series, T8 GENESIS® Series and T9 Series, will feature ECOBlue™ Hi-eSCR technology—an evolution of the existing ECOBlue™ SCR system—to meet the government’s new Tier 4B emissions standards. New Holland is providing its customers with a consistent solution that is already proven in more than 35,000 machines working around the world. Our SCR-only, single system solution for tractors over 100 horsepower maintains all of the productivity increases gained from Tier 4A in terms of power, torque, transient response and engine power management, while maintaining consistent operation and the same or better total fluid consumption from equivalent Tier 4A machines.


Efficient Emissions Solution

The primary focus was the reduction of Nitrogen Oxide (NOx) and Particulate Matter (PM). Aggressive standards have continued to be implemented since that time to reduce the amount of these pollutants being released into the atmosphere. The latest emissions standards are known as Tier 4, which have been implemented in a two-prong approach, Tier 4A and Tier 4B, which starts in 2014. Since the introduction of these stringent regulations in 1996, Nitrogen Oxide (NOx) and Particulate Matter (PM) have been reduced by 95%.


Traditionally, there have been two different engine solutions for meeting the Tier 4 regulations: SCR (Selective Catalytic Reduction) and CEGR (Cooled Exhaust Gas Recirculation). The fundamental difference between SCR and CEGR is that SCR controls the PM internally by allowing the engine to run as efficiently as possible, then converting the NOx outside the engine to nitrogen and water by treating it with urea (or DEF). CEGR, on the other hand, reduces NOx inside the engine by reducing combustion temperatures. However, this reduction produces more PM, which must then be filtered out externally by a particulate filter.


SCR is an after-treatment system that is separate from the main engine function and does not compromise horsepower or torque. It does not interfere with engine’s performance, but actually improves it. Exhaust gas is NOT recirculated through the engine and it does not require regeneration of particulate filters, which can compromise efficiency. SCR technology is the best approach for larger, higher-horsepower agricultural power products, especially when considering the importance of fuel efficiency and maintenance costs.

Powered By ECOBlue™ HI-eSCR Engine Technology

New Holland high-horsepower tractors are powered by ECOBlue™ HI-eSCR (Selective Catalytic Reduction) engines, which are designed and developed in house by FPT Industrial. As part of the Clean Energy Leader strategy, our proven high-efficiency SCR technology uses AdBlue® Diesel Exhaust Fluid (DEF) to transform the harmful nitrogen oxides contained in the exhaust gas into harmless water and nitrogen. This after-treatment system is separate from the main engine, which means only clean, fresh air is fed into the engine. What does this mean? Clean-running power units that offer improved performance, greater reactivity and enhanced fuel efficiency.


These engines, which comply with the even-more-stringent Tier 4B emissions norms, offer you four key benefits:


  • Performance: New Holland engines continue to provide industry-leading power, torque, transient response and Engine Power Management. The ECOBlue ™ Hi-eSCR after-treatment system enables the engine to breathe clean, fresh air, therefore optimizing its combustion, power and torque density.
  • Efficient Operation: ECOBlue™ HI-eSCR is an after-treatment system that does not interfere, or restrict, the engine’s performance, enabling it to maximize its efficiency and power. Total fluid consumption will be the same or better compared to equivalent Tier 4A machines, and this system enables New Holland to continue leading the industry with 600-hour service intervals.
  • Simplicity: New Holland uses a single system solution with less complexity. Since no exhaust gas is recirculated through the engine, no additional cooling requirements are needed, allowing the engine to operate at peak efficiency, while optimizing power and torque.
  • Consistency: The New Holland system uses proven technology with more than 35,000 machines working around the world, and requires no change in tractor operation from Tier 4A.

The Key Components of HI-eSCR

The key additional components of FPT Industrial’s ECOBlue™ HI-eSCR system are:


  • Patented closed loop system Using additional sensors located at the exhaust outlet of the engine, precise levels of NOx are recorded for exact DEF/AdBlue dosing. This enables the neutralization of even more NOx, without excessive DEF/AdBlue consumption.
  • Engine exhaust flap ensures the engine always operates at its optimum temperature, and it delivers efficient NOx conversion upon start up.
  • Diesel Oxidisation Catalyst (DOC) oxidizes the exhaust gas, guaranteeing the optimal mix between Nitrogen Oxide (NO) and Nitrogen Dioxide (NO2), increasing the conversion efficiency in the SCR catalyst.
  • Patented mixing pipe with an optimized fluid dynamic design. Delivering optimal exhaust gas and DEF/AdBlue mixing for the highest NOx conversion rates (over 95%) and the best use of the catalyst’s surfaces, to ensure the most efficient use of DEF/AdBlue.
  • Clean up catalyst (CUC) removes excess NH3 (Ammonia).

THE EMISSIONS REDUCTION STORY

1996 saw the introduction of the first Tier 1 emissions standards, and since then, nitrogen oxides (NOx) and Particulate matter (PM) have been reduced by 95%. With the introduction of Tier 4B regulations in 2014, NOx will be further lowered by 80%. These toxic substances are produced during combustion and can harm the environment and human health. NOx: nitrogen monoxide and nitrogen dioxide are produced during combustion when the engine is at its hottest. These gases are two of the main causes of acid rain and the shrinking ozone layer. PM: particulate matter is mainly made up of tiny carbon particles and other poisonous substances which are created when not all of the fuel is burned during combustion, generally when the engine is cooler.


YOUR GUIDE TO THE ECOBLUE™ HI-eSCR SYSTEM

Developed by new Holland’s sister company FPT Industrial, both the engines and the after-treatment system have been tailored to comply with new Holland customer-specific requirements, thus creating the ECOBlue™ HI-eSCR (High-Efficiency Selective Catalytic Reduction) solution which uses a catalyst to treat the NOx contained in the exhaust gas, transforming it into harmless water and nitrogen. To achieve this, it uses an after-treatment system that adds Diesel Exhaust Fluid (DEF)/AdBlue, a water and urea mix, which is colorless and non-toxic, to the exhaust stream. The solution developed by FPT Industrial is the most efficient in the industry, and is protected by seven different patents to guarantee you the most efficient operation. The entire system is managed by the engine control unit, which controls the Dosing Control Unit (DCU) and the supply module. This uses sensors contained within the closed-loop system to monitor the exhaust gases, and it uses this information to calculate the precise amount of DEF/AdBlue required.

New Holland is not going it alone when it comes to Tier 4 technology. They can draw on the experience of their in-house engine development group: FPT Industrial.


  • Pioneers: Fiat invented Common Rail technology in the 1980s. They were the very first to introduce it on agricultural machines on the TS-A tractor. Pioneering. Always.
  • Cleaner: Fiat Industrial has topped the Dow Jones Sustainability World and Europe indexes for the Industrial Engineering sector for two consecutive years.
  • Proven: FPT Industrial has pioneered SCR technology since 1995 and has already produced over 350,000 SCR engines during the last six years for the agricultural, construction and trucking industries. The award-winning Hi-eSCR solution has been extensively tested and has clinched numerous awards.
