EPA TPEM Program
TPEM or "Tier 4 Flex" is a program created by the U.S. EPA that allows original equipment manufacturers to continue selling Tier 3 engines after Tier 4 emission standards have been implemented. The intent of this program is to help ease equipment manufacturers through the transition to Tier 4 requirements and to delay the additional expense of purchasing more technologically advanced engines.
Tier 4 emissions standards require the reduction of particulate matter emissions by over 90 percent and nitrogen oxide emissions by 45 percent. This has driven the use of engine component technologies such as particulate filter after treatment, cooled exhaust gas re-circulation and variable geometry turbochargers in the new Tier 4 Diesel Engines. |
The implementation of Tier 4 Final carries with it a significant increase on the price of non-road diesel engines. Equipment manufacturers are faced with many difficult decisions as to how to stay competitive while trying to offset this dramatic cost increase.
If you are not participating in TPEM, then your company is allowing its competitors to gain a significant advantage by continuing to legally sell thousand’s* of Tier 2/Tier 3/Tier 4i engines each year for the next 7 years.
