Volvo Penta Will use SCR to Meet 2014 Emissions Regulations

Volvo Penta used SCR technology to meet the emission legislation in 2011. In order to keep it simple for the OEMs, the same technology will be used to comply with the stringent emission steps of 2014. For the OEMs this means no re-generation, limited installation challenges, continuous optimized fuel consumption and low operating costs.

It is true to say that the diesel power industry is in the middle of the most exciting and demanding times ever in terms of development challenges. The emission legislation introduced in North America and Europe in 2011 (Stage IIIB/Tier 4 Interim) forced all engine manufacturers to introduce after- treatment systems to deal with either nitrogen oxide (NOx) or particulate matter (PM).

This, in turn, has put enormous demands on original equipment manufacturers (OEMs) who need to re-design their machines to install the new engines and after treatment systems. To ease this transition, the authorities in Europe and North America have flexibility schemes that allow OEMs to place previous step engines, Stage IIIA/Tier 3, on the market within certain parameters. The outcome is a mixed picture of engine manufacturers and OEMs either ready for 2011, on time, or delayed and with one eye to the future storm clouds coming in 2014.

Within a three-year period, the same markets will be introducing the next step in the regulations: Stage IV/Tier 4 Final. This step changes the Nox from 2.0 g/kWh to 0.4 g/kWh, an 80% reduction. This will result in further changes to the engine and after-treatment systems on diesel engines that are to comply with the new regulations.

Volvo Penta’s strategy is to keep these changes as simple as possible. On 1 January 2011 Volvo Penta was ready with its range of engines compliant with Stage IIIB/Tier 4 Interim – and will be ready to meet OEMs’ needs in 2014.
The solution Volvo Penta put forward in 2011 was based on SCR, optimizing fuel consumption, same size cooling-package size and no re-generation. In 2014, Volvo Penta will achieve the same objectives again, no re-generation and limited installation challenges for OEMs and low operating costs.

Volvo Penta will be unveiling its Stage IV/Tier 4 Final product range at the Intermat exhibition in Paris, in April 2012. OEMs and operators are welcome to view and discuss the engines that will be on display.
