Wärtsilä, ABB and HUG to jointly develop next...

Wärtsilä Corporation, Trade Press release, 15 June 2010, at 6 pm (EET)

New SCR system promises more operational flexibility in conjunction with
2-stage turbocharging.

In an extension of their existing cooperation in the development of 2-stage
turbocharged medium speed diesel engines, Finnish power solutions provider
Wärtsilä and Swiss turbocharging specialist ABB Turbo Systems intend to
cooperate with a third partner, aftertreatment specialist Hug Engineering, based
in Elsau, Switzerland. The object of the new joint project is to develop an
innovative compact selective catalytic reduction (SCR) system especially
tailored to operation with two-stage turbocharging.

Under the envisaged agreement, Wärtsilä, ABB Turbo Systems and HUG Engineering
will target a further expansion of flexible engine operation at reduced NOx
emissions and optimized fuel consumption, as well as targeting savings in first
and life cycle costs. To develop the new combined SCR and turbocharging solution
and its integrated application on the engine, the partners will combine their
expertise and resources in order to achieve early readiness for market.

A further step in co-operation

In April 2010, Wärtsilä and ABB Turbo Systems announced about co-operation in a
joint development programme for a new and groundbreaking application of
two-stage turbocharging on large diesel engines. The application of two-stage
turbocharging technology on Wärtsilä diesel engines has been developed through
close co-operation between the two companies.

In this programme, Wärtsilä is focusing on developing advanced engine
technology, which with the turbocharger, is able to reach the highest possible
performance and become a cost-effective commercial solution for its customers.
ABB Turbo Systems is delivering the turbocharging technology with defined
performance in terms of airflow, pressure ratios and efficiency.
