On Jan. 1, 2011, the U.S. Environmental Protection Agency (EPA) introduced the next phase of its Tier 4 emissions control regulations, which will significantly reduce diesel emissions. Even if these regulations will not impact your business today, we want to assist you in learning about and gathering information for when you will need it.
Hawthorne Cat will introduce a family of Caterpillar products designed to meet the Federal Government’s Tier 4 Interim requirements for reduced emissions -- including application-specific products to better meet the unique needs of its customers. Caterpillar offers a full line of Tier 4 Interim engines for every application-with optimized emissions solutions tailored for each application.
Reduce Emissions with Cat Tier 4/Stage IIIB Technology
Emissions standards have been systematically reducing levels of Particulate Matter (PM) and Oxides of Nitrogen (NOx) since 1996 when the first standards went into effect.
From Tier 1/Stage I (1996) levels to Tier 3/Stage IIIA (2006), emissions standards required an approximate 65 percent reduction in PM and a 60 percent reduction in NOx.
The next phase of emissions standards, called Tier 4 Interim in the U.S. and Stage IIIB in the European Union, take effect in 2011. Compared to Tier 3/Stage IIIA levels, Tier 4 Interim/Stage IIIB standards require a 90 percent reduction in PM and a 50 percent decrease in NOx. Tier 4 Final/Stage IV standards, which will become effective in 2014, reduce NOx by an additional 80 percent, taking PM and NOx emissions to near-zero levels.
