How Cooled EGR Engines Meet IT4 Regulations with Doug Laudick

Doug Laudick, Manager of Product Planning at John Deere Power Systems (http://straightforwardblog.com) explains the technology at the center of John Deere’s path to Interim Tier 4 compliance: cooled exhaust gas recirculation, or “Cooled EGR.” Interim tier 4 regulations challenged OEMs, contractors and other customers to reduce particulate matter (PM) emissions by 90% and nitrogen oxide (NOx) emissions by 50% over final tier 3. At CONEXPO-CON/AGG 2011, Doug took the time to help us understand how John Deere’s Cooled EGR solution achieves this standard with minimal impact on customers.
