摘要

After more than 15 years of work, the end is in sight. A steady-stream of emission standards from the Environmental Protection Agency has prompted AGCO, Cummins, Fiat Powertrain Technologies, John Deere and other makers of off-road diesel engines to develop cleaner technologies. Today, manufacturers are preparing for Tier 4 Final compliance. The Tier 4 Interim standard required a 90% reduction in particulate matter and a 50% reduction in nitrogen oxides (NO_x). The final standard requires no further reduction in particulate matter but calls for an additional 80% reduction in NO_x.
