Maynard, Trevor . 2011. Diesel Aftertreatment Systems. 1151 1305P. San Dimas, CA: U.S. Department of Agriculture, Forest Service, San Dimas Technology and Development Center.
In 2001, the Environmental Protection Agency drafted new standards for diesel engine emissions, to be phased in gradually beginning in 2007. These requirements, developed to reduce the amount of particulate matter and exides of nitrogen produced by diesel engines, have led manufacturers to pursue new emission technologies. Aftertreatment sytems, devices which modify the chemical and/or physical composition of exhaust gases, have emerged as the leading technology. Though designed to require a minimal amount of driver intervention, most aftertreatment systems require some form of periodic maintenance. The purpose of this Tech Tip is to inform readers on the identification, operation, and maintenance of these new systems to ensure they do not hinder operations.
