This week, John Deere Power Systems is in Paris for INTERMAT 2012. Held every three years since 1988, INTERMAT (the International Exhibition for Equipment and Techniques for Construction and Materials Industries) is one of of the industry’s biggest international events.
At this year’s show, John Deere revealed its planned building-block approach to meet the upcoming challenge of Final Tier 4/Stage IV regulations. The Integrated Emissions Control system is a solution that optimizes engine performance, operating efficiency and reliability.
For Deere engines 56 kW (75 hp) and above, the Integrated Emissions Control system will consist of a diesel oxidation catalyst (DOC), a diesel particulate filter (DPF), and a selective catalytic reduction (SCR) system specifically designed to meet the unique demands of off-highway equipment. The DOC/DPF exhaust filter reduces PM while the cooled EGR and the optimized SCR system work to reduce NOx to Final Tier 4/Stage IV levels.
John Deere has already achieved a world-class fuel economy position with its Tier 3/Stage IIIA engines. Since then, we have continued to demonstrate industry leadership by developing solutions that not only considers fuel economy, but also a machine’s total fluid economy.
