This paper reviews the latest accomplishments in controlling gas emissions from large two-stroke diesel engines. During the last few decades several alternative methods have been developed, tested in service and evaluated for reduction of the exhaust gas emission. NOx emission can be reduced by Water Emulsion Fuel, High-pressure Water Injection, Exhaust Gas Recirculation (EGR), Scavenging Air Moistening (SAM), Low NOx Fuel Injectors and the Emission Mode of the ME Engine.
With regard to SOx emission it can be solved by Exhaust Gas Treatment. Operation on low-sulphur fuel Will also solve the problem. However, this requires special operational procedures.
The HC and particulate emission is the result of an insufficient combustion process. It is preferable to trace the reasons, as the resultant heat load and contamination has a negative influence on the engine's performance.
