John Deere Plans for Stage V Engine Changes | Construction News

John Deere Power Systems reports it has a modular building block approach to emission control that will transition from Stage IV/Tier 4 to anticipated Stage V regulations. This approach has led to a DPF solution capable of complying with the requirements indicated in the EU Commission’s proposal COM (2014)581 concerning Stage V emissions.

One of the significant impacts expected of Stage V will be the introduction of a particle number (PN) limit for engines in the 19 kW to 560 kW power band, which will necessitate use of DPF (diesel particulate filter) technology by OEMs. John Deere has been employing DPF technology since Interim Tier 4/Stage III B, with more than 150 million DPF hours logged in the field.

John Deere is leveraging new catalyst technologies and emissions control calibrations to enable downsizing of their after treatment. OEMs benefit by retaining the same engine performance in a reduced package size. The next generation after-treatment solutions from John Deere will deliver greater package flexibility and offer easier installation while providing up to a 20 percent reduction in size and up to 40 percent reduction in weight. 

“John Deere adopted DPF technology as part of an integrated emission control system because it is the best solution for most applications. By treating NOx and PM downstream of the engine, John Deere engines with DPF are optimized for increased torque response, low-speed torque, and fluid efficiency; and provide responsive power at higher altitudes,” said John Piasecki, director of marketing, sales and customer support for John Deere Power Systems.

John Deere Power Systems has experience with the development and integration of DPF technology in John Deere and OEM equipment through Stage III B and Stage IV implementation. This experience continues to lead to enhancements in efficiency and optimization of aftertreatment solutions that strengthen application flexibility for OEM customers.

Piasecki said John Deere recognizes as Stage V approaches, OEMs new to DPF technology may be worried it will add installation complexity or impact operational performance. “We are committed to helping OEMs through every step of the application process to make it as seamless as possible,” Piasecki said. “We are well positioned to transfer our experience level directly to our customers, giving them peace of mind and a distinct advantage in the process. John Deere has expertise in integrating the engine and drivetrain into the rest of the vehicle for optimized performance, operator convenience, fluid economy and overall value.”

John Deere is prepared for the growing complexity in world emissions standards; by 2022, there may be at least five different levels of emissions standards globally. “We are fully committed to supporting our customers around the world with solutions to meet their unique application needs,” said Geoff Stigler, director – sales, marketing and customer support – EAME, ASIA and AU for John Deere Power Systems. “OEMs, regardless of location, are best served through timely and strategic preparation, and John Deere is ready to help them identify and implement the best solutions for their business. Our modular building block approach offers greater application flexibility to help OEMs meet increasingly challenging machine design goals.”
