Integrated Emissions Control: Technology Tailored to Fit Your Application

From the start of increasingly stringent emissions regulations in 1996, John Deere has focused on adopting emissions-reduction technologies meeting regulatory requirements and customer needs. This carefully planned “building block” approach has led to our Integrated Emissions Control system — a Final Tier 4/Stage IV technology solution optimizing engine performance, operating efficiency and long-term durability.

John Deere defines the Integrated Emissions Control system as any configuration of aftertreatment and emissions-reduction components. We tailor these technology combinations to meet emissions and customer expectations in a variety of off-highway applications. There are two existing John Deere Integrated Emissions Control system configurations for Final Tier 4/Stage IV:

  • For engines below 56 kW (75 hp), we will offer a solution using an exhaust filter containing a DOC/DPF, without cooled EGR or SCR.
  • Our engines 56 kW (75 hp) and above will feature a configuration consisting of cooled EGR, a DOC/DPF and SCR.

The DPF is being used to provide optimized performance and fluid economy. The Integrated Emissions Control system configuration with SCR will meet emissions regulations while using low levels of DEF — 1 to 3 percent of diesel fuel consumption depending on the application. Low DEF consumption means DEF tank size can be smaller, which minimizes the impact on vehicle applications while extending DEF filter service intervals and reducing operator involvement.

All John Deere Integrated Emissions Control system configurations are specifically designed to meet the demands of off-highway applications. We’re excited about showcasing our Final Tier 4/Stage IV lineup at bauma 2013, April 15 – 21 in Munich.
