CASE ANNOUNCES ITS TECHNOLOGY CHOICES FOR MEETING TIER 4 EMISSIONS STANDARDS
| March 01, 2010 |
RACINE, Wis. (February 25, 2010) – Case Construction Equipment today announced that it is ready to meet the next two phases of emissions requirements. Tier 4 interim standards begin in 2011, and Tier 4 final standards come into effect beginning in 2014. Case is using two distinct technologies, cooled exhaust gas recirculation (CEGR) and selective catalytic reduction (SCR) to address Tier 4 interim standards across its product line, which includes more than 90 equipment models, ranging from 11.3 kW (15.15 hp) to 397 kW (532 horsepower).
The challenge in trying to meet Tier 4 standards—interim and final—is that the CEGR technology that reduces nitrogen oxides (NOx) increases particulate matter (PM) levels, while the SCR technology that reduces PM levels increases NOx levels. In order to meet the ultimate goal of near-zero emissions, an after-treatment exhaust filter system must be part of a CEGR solution, and a diesel exhaust fluid additive must be part of an SCR solution.
Case sees advantages to both technologies depending on engine size and load and also application demands, and it is taking advantage of the tremendous resources available to it as part of the Fiat Group, as well as the strengths of its worldwide strategic partners and suppliers.
Case has an excellent track record of meeting customer needs for increased productivity, improved fuel efficiency, increased uptime, best-in-class serviceability and operator comfort. And these improvements have been made with an eye toward the environment.
When Case machines meet Tier 4 final standards, they will have achieved a 90-percent reduction in particulate matter and nitrogen oxides, compared to Tier 3.
Benefits of SCR and CEGR
SCR is a cool-running, quiet system that’s separate from the main engine function and does not compromise horsepower or torque. It does not interfere with engine performance and, in fact, it actually improves performance. The SCR after-treatment system requires the addition of a diesel exhaust fluid.
CEGR technology provides a user-friendly solution that requires no change in the operation of the machines. It is a system that relies on an exhaust filter system to remove particulate matter from the exhaust. This technology provides excellent durability and low maintenance costs.
Case developed its SCR and CEGR technologies to ensure that customers continue to receive the productivity they expect from their Case equipment while complying with Tier 4 interim and eventually Tier 4 final standards.
