Cummins - On-highway experience brings benefits to the Tier 4 off-highway engines for 2011 and 2012

摘要

As one of the largest manufacturers of diesel engines - on and off road - and with thousands of OEM customers worldwide, Cummins came to the Tier 4 interim standards with three basic mandates: Keep it simple; Keep it flexible; Introduce the right technology for Tier 4i to minimize changes for Tier 4 final. A big part of being able to meet the first two goals was the creation some 10 years ago of Cummins Emissions Solutions. This division of the company manufactures aftertreatment devices for on- and off-road engines as well as retrofit applications, and the experience garnered there played a significant role in the company's ability to develop robust aftertreatment technology for Tier 4i.
