CNH to Use Both SCR and EGR in Tier-4 Strategy

February 25, 2010

Case, New Holland and Kobelco have announced that they are 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.

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.

Sounds like there will be a lot of old machines staying in the working environment if this does happen.  The fuel consumption on the new Fords with a particulate filter exhaust is drastically increased as to the old engines and one has to have the filter maintenance runs to keep them clear:  Sitting at high rpm in the drive burning the particulates off after the damn thing loads up.  I do not see the benefit of using more fuel to "decrease" emission levels, that does not add up.

Case or CNH isnt doing anything to meet the new standards, the press release obviously written by someone at CNH, specifically on the CaseIH side of it had put some "spin" on this. Cummins is the engine supplier to all of the CaseIH products so Cummins is achieving this standard. New Holland on the other hand has Fiat built Iveco diesel engines that the fiat group and NewHolland will use to achieve the tier 4 standards, in some of ther larger products. Not sure why these marketing guys always have to slide around the truth.
