The Nature and Cause of Internal Diesel Injector Deposits and the Effectiveness of Fuel Additives

该论文已在赫尔辛基举行的第28届CIMAC大会上发表,论文的版权归CIMAC所有。ABSTRACT In the late 1980’s the International Maritime Organisation (IMO) started work on reducing air pollution from ships. Since then in a parallel movement to automotive application, the introduction of further legislation and emission regulations have seen the introduction of low sulphur fuels (0.1% sulphur limit inside Emission Control Areas, meaning an unprecedented increase in MGO consumption) and common rail diesel injection equipment. Increasingly marine grade fuels are nearing the specification of that seen in the automotive industry, such as the potential introduction of FAME into ISO specs. As in the automotive industry, injection equipment manufacturers are also moving to increased pressure and temperature common rail systems. It can be noted that large two stroke engines are now also using Common Rail systems; however these are relatively low pressure at the rail (1000 Bar) and are often designed to operate on both MGO and HFO. Common rail engines not only offer improvement in emissions but are also more efficient and allow more operational flexibility than their predecessors. It is anticipated that next generation medium speed engines will increase the pressure at the rail and will continue to run on both HFO and MGO. High pressure common rail diesel engines are currently seen on MGO only vessels such as high speed Naval or Coastguard vessels.
