| Caterpillar receives Interim Tier 4/Stage IIIB engine certification Caterpillar Inc. (CAT: NYSE) announced that the company's C9.3 ACERT engine has received the United States Environmental Protection Agency'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 IIIB emissions regulations begin January 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 on 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. Additionally, the C9.3 ACERT engine is being offered in several configurations and ratings for use by customers in the industrial, agriculture and petroleum markets. By the time Tier 4 Interim/Stage IIIB products reach customers, the Caterpillar Tier 4 validation program will have accumulated nearly one million hours of operation, making it the most extensive validation effort in Caterpillar history. write your comments about the article :: © 2010 Construction News :: home page |
