SCR Looms on the Horizon - Selective Catalytic Reduction promises benefits for 2010

摘要

For 2010, the U.S. Environmental Protection Agency (EPA) will require a reduction in nitrogen oxide (NOx) from diesel engine exhaust. All but one engine supplier for medium- and heavy-duty trucks have announced they will be using a technique known as Selective Catalytic Reduction (SCR). While this is a proven technology, it will be the first time it is implemented on heavy-duty trucks in North America.
