论文已在中国上海举行的2013年CIMAC大会上发表，论文的版权归CIMAC所有。With the upcoming reduction in fuel sulfur content there are concerns in the shipping industry for the future fuel quality and availability. The future fuel quality may also affect the particulate matter(PM) emissions in a negative way despite the significant reduction in PM mass that will be achieved by reducing the sulfur concentration in heavy fuel oils(HFO). The remaining PM emissions may increase if the fuel quality decreases in the future due to the reduced fuel sulfur content. The authors are looking for a method that allows simple and cheap comparison of different fuel qualities without the need for full scale testing on large marine engines. The idea is to use the FIA-100/FCA(FIA) or similar device for fuel combustion and estimating the PM emissions by measuring the particle size distribution (PSD) in the FIA exhaust. This study is looking into the possibilities and the objectives were to establish whether or not it was possible to see any effect of fuel quality on the measured PSDs and if the changes in PSDs resembled what is observed in real engines. This study shows that it is possible to observe the effect of fuel quality in the FIA PSDs although the behavior was not exactly the same as observed in a real engine. The agreement for high quality fuels such as marine gas oil, gas to liquid fuel and fish oil was good while there are improvements to be made for the HFO measurements. Further improving the method will probably require the flexibility of the Fuel tech combustion research unit (CRU) or similar equipment and improvement to both sampling and measurement methods.
