目前,各国为提高低速柴油机的经济性,正在竞相开发应用劣质燃料油。国产海军舰用燃料油是军舰锅炉专用劣质燃料油,未曾作为低速船用柴油机燃料油使用过。这次,“极地号”船首次赴南极考察的远距离航途中,将此种油料作为该船主机燃料油,并获得较好的经济效益。 At present, in order to improve the economy of low-speed diesel engines, all countries are racing to develop and apply inferior fuel oils. Domestic naval marine fuel oil is a special low-grade fuel oil for warship boilers, and has never been used as low-speed marine diesel fuel oil. This time, the “Polar” ship made its first trip to Antarctica for long-distance voyages and took the oil as the host fuel of the ship and obtained good economic benefits.
