Cat gets non-road Tier 4 certification
Lauren Heartsill Dowdle | September 21, 2010

Caterpillar’s C13 ACERT and C15 ACERT engines received the United States Environmental Protection Agency’s Tier 4 emissions certification. The engines are the latest to receive certification in the 130- to 560-kilowatt power category.

These engines, in addition to the previously announced certified C9.3 ACERT engine families, will power a number of Cat products such as mid-range track-type tractors, motor graders and hydraulic excavators.

It is projected that Caterpillar will accumulate nearly one million hours of testing on Tier 4 Interim engines and machines by the end of 2010.
