T7 tractors boast New Holland's cutting-edge and award-winning ECOBlue™ HI-eSCR (High-Efficiency Selective Catalytic Reduction) engine technology, developed by New Holland’s sister company FPT Industrial. These engines comply with the even-more-stringent Tier 4B emissions standards. These T7 engines continue to “breathe” better and maintain the performance advantages you’ve come to expect from the T7 Series line.
This new system is an evolution of the existing ECOBlue™ SCR system, and you will benefit from the highest NOx conversion efficiency in the industry. This multi-patented system uses a new Engine Control Unit, which not only manages the engine, but also the HI-eSCR after-treatment system by controlling the supply and dosing modules. Using a dedicated closed-loop system, it continuously monitors the NOx levels in the exhaust gases, ensuring that during every cycle the precise amount of DEF is injected to Achieve NOx conversion of over 95%, all while guaranteeing low fluid consumption.
T7 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 breath clean, fresh air, therefore optimizing it's combustion, power and torque density.
ECOBlue™ HI-eSCR is an after-treatment system that does not interfere with or restrict the engine's performance, enabling it to maximize its efficiency and power. It does not require any exhaust gas to be recirculated through the engine and does not require regeneration of particulate filters. Total fluid consumption will be the same or better from equivalent Tier 4A machines, and this system allows New Holland to continue leading the industry with 600-hour service intervals.
ECOBlue™ HI-eSCR is 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. The New Holland system uses proven technology with more than 35,000 machines working around the world, and requires no change in tractor operation.
In applications where a constant PTO speed is required, just select Engine Speed Management. This ensures the speed you select is accurately maintained even under changing loads. In many applications, this allows you to maintain a fixed forward speed in difficult terrain.
Engine Power Management (EPM) is a renowned New Holland tractor feature. In short, the engine develops more power and torque according to the load on the transmission, hydraulics and PTO. Now T7 tractors also feature EPM when driving in reverse, ideal for snow blowing or mowing.
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 T7 Series’ impressive fuel efficiency, bringing about a substantial cut in your farm’s carbon emissions.
