LOW NO X CONVERSION PACKAGE<br />
The Low NO X conversion combines various<br />
engine modifications designed to obtain low<br />
NO X values. The modifications set the ideal<br />
combination of compression ratio, injection<br />
timing and injection rate.<br />
IMO TIER I UPGRADE SOLUTIONS<br />
The solutions focus on NO X emission<br />
reduction below the IMO Tier I NOx limits for<br />
2-stroke engines built between 1.1.1990 and<br />
31.12.1999. Depending on engine type and<br />
rating, the solution will consist of injection<br />
timing related modifications or a combination<br />
of injection timing and compression ratio<br />
related modifications. The solutions will<br />
be commercially available for most engine<br />
types, when they are registered with IMO as<br />
certified Approved Method. The regulation for<br />
engines built 1990-1999 will be in force as of<br />
01.07.2010.<br />
SELECTIVE CATALYTIC REDUCTION<br />
(SCR)<br />
SCR is currently the most efficient method<br />
of NO X reduction. The SCR method reduces<br />
NO X emissions by 85-95%. Hence, it is easy<br />
to reach NO X level of 2g/kWh or lower, which<br />
complies with the most stringent emission<br />
limits.<br />
