Tier 4: Past, Present, and Future Technologies for Meeting Regulatory Challenges

Thursday, October 20, 2011: Noon ET

With 2011 Tier 4 Interim engines currently in the field proving their worth not only in terms of meeting increasingly stringent emissions regulations but also exceeding efficiency and productivity expectations, engineers throughout the off-highway industry are looking to finalize just what technologies will go into future diesels to meet 2014 Tier 4 Final regulations. Panelists will discuss some of the challenges that presented themselves in meeting T4I and what technologies were used to mitigate and master those challenges. While many of the engine and aftertreatment technologies used in T4I are expected to also prove vital for 2014, some may either not make the cut or have to undergo marked improvements. Panelists will discuss why meeting T4F has forced engineers and designers to focus with an almost microscopic intensity on the most esoteric components of the engine and aftertreatment, and, simultaneously, on the equipment itself, as the optimization of every vehicle system becomes a critical part of the ultimate solution. Also, what is next? Panelists will give some insight into what the next set of rules and regulations may look like for the off-highway industry and some of the technological solutions that may follow.
