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.
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.
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:
The key additional components of FPT Industrial’s ECOBlue™ HI-eSCR system are:
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.
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.
Emissions released from burning diesel are a significant contributor to a farm’s overall carbon footprint. ECOBlue™ Hi-eSCR technology for Tier 4B compliance reduces NOx emissions and maintains the impressive fuel efficiency of New Holland high-horsepower tractors, bringing about a substantial cut in your farm’s carbon emissions.
