Recently, exhaust emissions from marine engines have become a cause of growing concern. Emission reduction technologies applicable to marine engines need to be developed and tested so that the emission regulations can be met. A review of emission reduction technologies applicable for marine engines is presented in this study. The experimental results of onboard testing of a high-speed passenger ferry to determine the benefits of low sulfur diesel (LSD) fuel and intake air water injection are presented. Gaseous emissions of oxides of nitrogen (NOx), carbon dioxide (CO2), and particulate matter (PM) emissions were measured using on-board emission measurement systems developed at the Engine and Emissions Research Laboratory (EERL), West Virginia University. The NOx emissions were reduced by approximately 11%--17% with intake air water injection and, the PM emissions were reduced by approximately 38%--45% with operation on LSD fuel without a penalty in fuel consumption or work output.
