John Deere Engines 130 kW and Above Earn Final Tier 4, Stage IV, CARB Certification

John Deere customers can be confident in our tailored Final Tier 4 Integrated Emissions Control systems. That was confirmed with the recent announcement that our engine lineup 130 kW (174 hp) and above achieved U.S. Environmental Protection Agency (EPA) Final Tier 4, European Union Stage IV and California Air Resources Board (CARB) emissions certification. The PowerTech PVS 6.8L, PowerTech PSS 6.8L, PowerTech PSS 9.0L and PowerTech PSS 13.5L models are our first engines to receive Final Tier 4, Stage IV and CARB certification in the 130 kW to 560 kW (174 hp to 750 hp) power segment.

We worked with our customers throughout the design process to ensure that our innovative Final Tier 4/Stage IV emissions solutions will provide not only emissions compliance, but also leading performance and low operating costs. To meet the Final Tier 4/Stage IV challenge for engines 130 kW (174 hp) and above, we followed our planned building-block technology approach. We equipped our 93 kW (125 hp) and above engines with an Integrated Emissions Control system consisting of cooled EGR, a DOC/DPF and an SCR system.

With the use of SCR technology for Final Tier 4/Stage IV, we’re confident that our total fluid operating costs will maintain an industry-leading position. DEF consumption with John Deere Final Tier 4/Stage IV engines will be 1 to 3 percent of diesel fuel consumption depending on the application. With diesel fuel economy gains achieved through increased injection pressures and the optimized Integrated Emissions Control system, we expect our Final Tier 4 engines to improve upon the total fluid economy of our Interim Tier 4 engines. Low DEF consumption also means the DEF tank size can be smaller, minimizing space required on equipment.

We have adopted the best available technologies to meet Final Tier 4/Stage IV regulations in each power range, and we’re confident that all our solutions will deliver power, performance, ease of operation, fluid efficiency, reliability, durability and economical operating costs in addition to emissions compliance.
