| Caterpillar showcases Tier 4 Interim//Stage IIIB products Construction and mining equipment maker Caterpillar Inc. showcased its Tier 4 Interim//Stage IIIB readiness at an emissions strategy update event for industry professionals at the company's Edwards, Illinois, Learning and Demonstration facility. Caterpillar's Tier 4 Interim//Stage IIIB engine technology includes state-of-the-art integrated system design built upon the success of the company's ACERT technology. Additional technologies, including powertrain innovation and aftertreatment devices, will be specifically tailored and applied to products to provide maximum value to customers while meeting the stringent emission requirements mandated by law. In 2004, the Environmental Protection Agency and the European Union introduced Tier 4 and Stage IIIB/IV emission standards respectively, with effective dates ranging from 2008 to 2015. Tier 4//Stage IV standards require emissions of particulate matter (PM) and oxides of nitrogen (NOx) to be reduced by more than 90 percent. It is projected that Caterpillar will accumulate nearly one million hours of testing on Tier 4 Interim//Stage IIIB engines and machines by the end of 2010. During the strategy update, Caterpillar previewed some of its newly developed machines including a 336E Hydraulic Excavator, 140M Motor Grader, 980H Wheel Loader and 775 Off-Highway Truck. The company will also showcase its Tier 4 Interim//Stage IIIB readiness at the international trade show, bauma 2010, this April in Munich, Germany. write your comments about the article :: © 2010 Construction News :: home page |
