Caterpillar C9.3 ACERT Engine
Caterpillar’s C9.3 ACERT engine has received the U.S. EPA Tier 4 emissions certification and European Union (EU) emissions type approval.
The C9.3 ACERT is the first Caterpillar non-road engine to receive emissions certification in the 130-560 kW power category. Interim Tier 4/Stage III B emissions regulations began Jan. 1, 2011 for 130-560 kW engines and require a 90 percent reduction in diesel particulate matter (PM) and a 50 percent reduction in nitrogen oxide (NOx) from previous Tier 3/Stage IIIA requirements. ACERT is an advanced combustion technology that uses a building-block approach for reducing emissions that is based the integration of key systems technologies. The C9.3 ACERT engine family will power a number of Cat products including mid-range track type tractors, motor graders and hydraulic excavators in a wide variety of customer applications. catrequests@cat.com
