Case IH to use Selective Catalytic Reduction technology to meet Tier 4B engine emission standards


To meet the 2014 Tier 4B (Tier 4 Final) engine emission standards, Case IH has announced that it will use exclusively Selective Catalytic Reduction (SCR) technology. That’s the same technology that Case IH is using to meet Tier 4A interim standards in high-horsepower tractors.

The Tier 4 standards, which have been phased in over a number of years, will become final in 2014, and will require a minimum 90 percent reduction in particulate matter and nitrogen oxides (NOx) compared to Tier 3 requirements.

SCR is an engine exhaust after-treatment system that works outside the engine in the exhaust system. With SCR technology, daily engine maintenance and upkeep are easy, because SCR treats exhaust to eliminate NOx after it exits the engine, allowing the engine to perform at peak efficiency, according to the company.

For Case IH customers who have purchased Tier 4A equipment, there will be no additional requirements in 2014.

With Tier 4 final regulations a little more than two years away, what are you doing to prepare?
