With Tier 4i standards for diesel emissions in effect as of January 1, 2011—and Tier 4 final looming in 2014/2015—MTU Onsite Energy is offering a new white paper about EPA compliance for generator sets. The free download is available at MTU Onsite Energy. “Understanding Tier 4 Interim and Tier 4 Final EPA Regulations for Generator Set Applications” provides an overview of the EPA’s standards as they relate to emergency stationary power (ESP) and other generator set applications.
The paper explains that for applications other than ESP, Tier 4 regulations for generator sets are being phased in two steps, beginning with Tier 4 I in 2011. Applications included are load management/peak-shaving, prime power, mobile rental power and spark-ignited engine generators used in non-ESP applications. Diesel generators used for emergency power in California and non-attainment areas throughout the U.S. are subject to the Tier 4 standards. The document also reviews the in-engine design changes and exhaust aftertreatment options that generator set manufacturers are applying to reduce engine emissions.
The free emissions regulations paper is available from local MTU Onsite Energy distributors or can be downloaded from MTU Onsite Energy’s “Technical Info” section at
