We talked about the engines for automobiles and ships in the last article.<\/span><\/p>\n This time we would like to share information about the fuel to power the engine.<\/span><\/p>\n <\/p>\n The same raw materials are used regardless of ships and automobiles, but not the same type.\u00a0<\/span><\/p>\n Of course, the raw material is petroleum.<\/span><\/p>\n So, what is the difference?<\/span><\/p>\n Gasoline is used for automobiles.\u00a0<\/strong><\/p>\n On the other hand, heavy oil is used for ships.<\/strong><\/p>\n <\/p>\n <\/p>\n <\/p>\n Petroleum is a mixture of many components such as gasoline and kerosene<\/span><\/p>\n Those components are extracted by distillation.\u3000<\/span><\/p>\n The remaining residue after the extractions of various components is used as heavy oil and asphalt.<\/span><\/p>\n Heavy oil is classified into three categories : A, B and C Types<\/span><\/p>\n A type heavy oil is the one mixed with 90% light oil.<\/strong><\/p>\n B type heavy oil contains 50% light oil and 50% heavy oil.<\/strong><\/p>\n C type heavy oil contains 90% heavy oil.<\/strong><\/p>\n C type<\/strong> heavy oil<\/strong> is mainly used as fuel for ships.\u00a0<\/span><\/p>\n <\/p>\n <\/p>\n The price is the main factor.<\/strong><\/p>\n Since the huge vessels consume a large amount of fuel everyday (dozens of tons per day!) to power the engines, they use C type heavy oil which is inexpensive.<\/span><\/p>\n Furthermore, A type heavy oil is not only used as fuel but as another purpose for which it is\u00a0 filled with the piping connecting to the engine to prevent fuel sticking.<\/span><\/p>\n C type heavy oil must be kept its liquidity at high temperature all the time.<\/span><\/p>\n When a ship needs to be parked for a long period of time, the piping from the fuel tank to the engine will be cooled and C type heavy oil will get solid in it, resulting in the clogging.\u00a0<\/span><\/p>\n A type heavy oil does not get solid due to 90% light oil, different from C type heavy oil.<\/span><\/p>\n <\/p>\n <\/p>\n Although C type heavy oil is affordable, it has the disadvantage that a large amount of exhaust gas is generated <\/span>when C heavy oil combusts.<\/span><\/p>\n In January 2020, IMO (International Marine Organization) established emission control regulation to prevent air pollution.<\/span><\/p>\n This strict regulation does not allows ships belching black exhaust from the chimney <\/span> Since the regulation was enacted, we are working on the improvement of the environment by changing fuels to less exhaust-intensive ones and by installing emission gas cleaning equipment (scrubber systems) in chimneys.<\/span><\/p>\n <\/p>\n <\/p>\n<\/h2>\n
Is the same engine fuel used for ships and automobiles?<\/span><\/h2>\n

Is inexpensive C type heavy oil safe?<\/span><\/h3>\n
\n<\/span>to enter some countries.\u00a0\u00a0<\/span><\/span><\/p>\nWhat is the difference between gasoline and C type heavy oil?<\/span><\/h2>\n
