| Abstract |
In December 2007, EPA published an Advanced Notice of Proposed Rulemaking to enact more stringent exhaust emission standards for engines on ocean going vessels. New NOx and SOx exhaust emission standards were discussed for engines on Category 3 marine vessels. Two new tiers of NOx standards have recently been adopted by the IMO. Tier II NOx standards are roughly 20 percent lower than the existing Tier I NOx standards set by the International Maritime Organization in Annex VI. To meet these standards, in-cylinder emission control approaches such as electronically controlled high pressure common rail fuel systems, turbocharger optimization, compression ratio changes and electronically controlled exhaust valves could be used. Tier III NOx standards which only apply in designated Emission Control Areas are roughly 80 percent below Tier I NOx standards and would likely require exhaust aftertreatment such as selective catalytic reduction (SCR). Other approaches that may be considered to reduce NOx emissions from Category 3 vessel engines are exhaust gas recirculation and water technologies such as direct water injection or fumigation. |
