Origin of particle emissions of a new IMO NOx Tier 2 category cruising ship compliant with European SOx emission control areas

Research output: Contribution to conferenceConference AbstractScientific


Parameters affecting exhaust particle emission rates from a new Tier 2 NOx emission category ship were investigated. The ship was operated with current emission control area (ECA) compatible fuel that contains max. 1 % sulphur S and in EU port areas with the allowed fuel quality of max. 0.1 % S. The operation of the ship was realistic containing cruising at sea and transitional manoeuvring and port operations. In addition, changes in particle emission rates during gradual power increase 10 % -> 100 % were analysed. Particle number PN emissions were analysed on continuous basis with ELPI, and particle mass PM emissions both from the hot stack (ISO9096) and from diluted and cooled exhaust (ISO8178:2006). The most pronounced reduction on PM and PN emission rates was associated with fuel quality, not with engine load or ship's operational mode
