International Maritime Organization has been increasingly strengthening the emission standard for marine environment protection. Regulations of GHG, SOx and NOx have been enforced. Now, restrictions on particulate matters (especially back carbon) have being discussing on MEPC and PPR of IMO. Many studies are performing application of after-treatment system like scrubber, electrostatic precipitator and diesel particulate filter for reduction particulate emissions. This study was conducted using a high speed marine diesel engine equipped with DPF. The results revealed that about 80% reduction rate of particulate mass measured at upstream and downstream of DPF. We are planning to utilize the result for developing DPF equipped with burner system for regeneration.

The effort of reducing sulfur oxides and particulate emission lead to limits on sulfur content in marine fuels. Additionally, regulation of particulate emission is discussed at International Maritime Organization, which means conversion from indirect to direct control. In this respect, an experimental study was conducted on a high speed diesel engine fuelled with ultra low sulfur diesel (ULSD) and relatively higher sulfur diesel fuel (HSD) to investigate engine-out emission characteristics (especially particulate emission). The results represented the particulate mass for HSD increased by a maximum of 1.9 times compared to ULSD, which can be explained by higher sulfur contents within HSD. This shows reasonable consistency with the results of analysis on particulate component.
