John Deere Power Systems prepares for Stage V emissions

John Deere Power Systems says its current engine line-up is already capable of meeting the expected Stage V emissions levels as a result of fitting DPF technology to meet current emissions requirements. It anticipates one of the significant impacts of Stage V to be the introduction of a particle number (PN) limit for engines in the 19-560kW power band, which will force the use of DPF technology.

John Deere Power Systems’ experience with DPF over the last five years puts it on target to meet expected Stage V emissions regulations

257 John Deere Power Systems says its current engine line-up is already capable of meeting the expected Stage V emissions levels as a result of fitting DPF technology to meet current emissions requirements.

It anticipates one of the significant impacts of Stage V to be the introduction of a particle number (PN) limit for engines in the 19-560kW power band, which will force the use of DPF technology.

John Deere has been employing DPF technology since the introduction of Stage IIIB in 2011, and has amassed more than 150 million DPF hours of in-field use.

“DPF technology is very familiar to us,” explained Martin Ryley, John Deere Power Systems’ manager of marketing support and sale engineering. “And our dealer network is comfortable with it too.”

It means Deere engines will continue to use a combination of existing technologies, including cooled EGR, which is said to contribute to the use of a smaller SCR package.

New catalyst technologies and emissions control calibrations will enable downsizing of after-treatment systems. And the next generation after-treatment solutions from John Deere are expected to deliver greater package flexibility and easier installation, while providing reductions of up to 20% in size and 40% in weight.

    New engine emission regulations pose major challenges for engine manufacturers - Geoff Ashcroft reports. The arrival of emissions regulations in January for engines over 130kW has meant that engine makers have adopted varied technologies to meet and exceed those goals. For the end user though, buying new kit that complies with Tier 4 Interim/Stage IIIB emissions regulations is likely to carry additional costs.
