John Deere Power Systems Receives Final Tier 4 Certification on PowerTech Engine Lineup

July 19, 2013
John Deere Power Systems last week announced that its engine lineup 130 kW (174 hp) and above has received U.S. Environmental Protection Agency Final Tier 4, European Union Stage IV and California Air Resources Board emissions certification.
John Deere Power Systems has reached Tier 4 Final certification on its PowerTech engine line-up 130 kW and above.

John Deere Power Systems last week announced that its engine lineup 130 kW (174 hp) and above has received U.S. Environmental Protection Agency Final Tier 4, European Union Stage IV and California Air Resources Board emissions certification. The PowerTechTM PVS 6.8L, PowerTech PSS 6.8L, PowerTech PSS 9.0L and PowerTech PSS 13.5L models are the first John Deere off-highway engines to receive Final Tier 4, Stage IV and CARB emissions certification in the 130 kW to 560 kW (174 hp to 750 hp) power category.

“We began the design process by listening to our customers, and we have worked with them every step of the way to ensure our solutions deliver the industry-leading performance and low operating cost they expect from John Deere,” said Geoff Stigler, manager of worldwide marketing for John Deere Power Systems. “Our building-block approach has enabled us to adopt the best available technologies to meet each new regulatory tier, and this continues with Final Tier 4/Stage IV.”

Final Tier 4/Stage IV emissions regulations begin Jan. 1, 2014, for engines 130 kW and above, and require an 80-percent reduction in nitrogen oxides (NOx) from previous Interim Tier 4/Stage III B requirements. Particulate matter levels remain the same as those mandated by Interim Tier 4/Stage III B regulations.

For Final Tier 4/Stage IV, John Deere continued with its planned building-block approach by developing the Integrated Emissions Control system to meet the standards. For 93kW (125 hp) and above engines, John Deere will offer models equipped with an Integrated Emissions Control system configured with cooled exhaust gas recirculation, a diesel oxidation catalyst and diesel particulate filter, as well as an selective catalytic reduction system. The DOC/DPF reduces PM while cooled EGR and the SCR system reduce NOx.

“The certifications of our PowerTech engines 130kW and above are tremendous milestones for John Deere, and confirm that our customers can be confident in our tailored Integrated Emissions Control systems, which deliver innovative technologies capable of meeting more stringent emissions standards,” Stigler said. “We are confident that all of our Final Tier 4/Stage IV solutions will provide the power, performance, ease of operation, fluid efficiency, reliability, durability and economical operating costs customers expect from John Deere.”

John Deere Power Systems manufactures and markets 30 kW to 448 kW (40 hp to 600 hp) industrial diesel engines and 56 kW to 559 kW (75 hp to 750 hp) marine diesel engines, as well as drivetrain components for use in a variety of off-highway applications.
