Attempts by the European Commission to reduce air pollution poses new challenges for engine manufacturers in the form of Stage V emissions standards. Many manufacturers can use their knowledge and experience with on-road developments to ensure off-road engine developments work efficiently.
Following on from our previously published Stage V emissions article and discussions around tougher standards for more engine types; After-treatment systems for smaller engines; and DPF in the after-treatment system, John Deere has become one of the first to release their developments.
In December 2016, John Deere (JD) announced their lineup of Stage V ready engines to meet the implemented European Union (EU) Stage V emissions regulations. Leveraging new catalyst technologies, emissions control calibrations and next generation after-treatment solutions, John Deere PowerTech™ engines will deliver greater package flexibility and offer easier installation over previous John Deere engines.
The lineup of Stage V ready engines have been optimized for increased torque response, low-speed torque, fluid efficiency, and provides responsive power at higher altitudes.
Martin Ryley, JDPS commented:
“John Deere is committed to helping OEMs through every step of the application process, ... well positioned to transfer our experience from various applications and operating conditions directly to our customers, giving them peace of mind. OEMs, regardless of location, are best served through timely and strategic preparation, and JD is ready to help them identify and implement the best solutions for their business.”
OEMs will benefit from the continual product improvements and advancements JD has made by retaining the same engine performance in reduced package size.
Ryley added that to achieve Stage V emissions levels for engines in the 19 kW to 560 kW power band, manufacturers will have to use DPF technology.
John Deere Power Systems has extensive experience with the development and integration of DPF technology in both JD and OEM equipment through Interim Tier 4/Stage III B and Final Tier 4/Stage IV implementation. OEMs new to the technology will be able to leverage their experience as they transition to Stage V.
“Our experience with DPF technology clearly sets a benchmark in the industry that positions JD as a leader capable of helping customers seamlessly transition to Stage V,” Ryley said. “That depth of experience extends throughout our distributor network and with all JD service dealers, giving us a distinct advantage.”
JD will continue to look for additional opportunities to make improvements to existing technology, leading to development of new engine offerings that will continue to meet emissions regulations, while providing reliable, durable products.
John Deere Power Systems manufactures and markets industrial, marine, and generator drive diesel engines, as well as drivetrain components for use in a variety of off-highway applications.
