Sufficient attention to fuel oil systems, which is one of primary factors to revitalize marine transportation, is a great importance. Today's fuel oil used aboard sea-going vessels is low-grade heavy fuel oil (densit-1.0g/cm3@15°C, kinematic viscosity-500cSt@50°C) which requires complicated heating systems and excessive heating energy. This causes hard-working environment to engineer crew due to high temperature in engine room (approximately45-50°C) . Still more, because of high heating temperature (approximately80-100°C) some fine components of fuel likely degenerate, coke or is wasted.
This study proposes a new usage of heavy fuel oil without heating, by mixing heavy fuel oil with oil thermally processed from waste plastics (hereafter called Waste Plastic Disposal or WPD) . In previous papers, authors have presented the achievement of application of WPD-mixed DO and WPD-mixed A.Oil to diesel engines.
This paper reports the result of application of non-heated WPD-mixed HFO to diesel engines including the inspection of engine functions and exhaust gas characteristics.
