For a long period, marine diesel engines were solely fueled with the distillate type of fuels. The higher fuel cost required also an improvement in the overall efficiency of the marine propulsion systems. The hydrocarbon composition of marine diesel fuels depends mainly on that of the crude oil used in the refinery but on the secondary refinery process units, e.g. aromatics content when the highly aromatic catalytic cracker cycle oil is used as a component in the residual fuels. Water content is often increased after delivery in the ships fuel tanks, either because of leakage into the tank or by tank breathing and condensation.encrude oil distillationhydrocarbon compositionmarine diesel enginesmarine diesel fuelsmarine fuelswater contentEngineeringBook part10.1002/9783527813490.ch26Other
