Interim Tier 4/Stage III B emissions regulations begin January 1, 2011 for 174 horsepower and above engines and require a 90 percent reduction in diesel particulate matter (PM) and a 50 percent reduction in nitrogen oxide (NOx) from previous Tier 3/Stage III A requirements.

John Deere met the challenge of Interim Tier 4/Stage III B regulations by starting with their proven PowerTech Plus Tier 3/Stage III A in-line, six-cylinder engine platform — which includes cooled exhaust gas recirculation (EGR) for NOx control — and adding an exhaust filter for reducing PM. These engines will feature full-authority electronic controls, a four-valve cylinder head, a high-pressure fuel system, turbocharging and an air-to-air aftercooling system.

With their Interim Tier 4/Stage III B engines featuring cooled EGR and VGT technologies, John Deere expects to maintain fuel-economy levels similar to those achieved with their Tier 3/Stage III A engines. John Deere’s cooled EGR engines operate efficiently with ultra low-sulfur diesel as well as biodiesel blends, providing owners and operators with optimal performance and fuel-choice flexibility.

In choosing a solution for Interim Tier 4/Stage III B, John Deere elected not to use selective catalytic reduction (SCR). John Deere’s cooled EGR and exhaust filter approach provides OEMs and end-users a proven solution with the best total fluid economy. The single-fluid approach of cooled EGR means owners and operators won’t have to incur the cost of diesel fuel plus the additional cost for diesel exhaust fluid (DEF) required by SCR systems.

The certified and compliant PowerTech PVX 9.0L offers up to 300 horsepower while the PowerTech PSX 9.0L offers up to 425 horsepower. PowerTech 9.0L engines went into production in May 2010. 309.765.8000, www.deere.com
