第3题:

Have you ever served the auxiliary engine to combustion heavy oil? What should be borne in mind when transferring oil; from heavy oil to light oil?


正确答案:I have ever served the auxiliary engine to combustion a combination of A and C oil. When transferring oil from heavy oil to light oil, the changing of temperature should not be rapid. 1℃ to 2℃ per minute is the best. Meanwhile the viscosity changing is invariably observed. The oil temperature to be heated varies in quality of fuel oil. In general, 180 CST needs to be heated to 95-105℃; 380 CST needs to be heated to 130-135℃. The viscosity is under the control of approximately 2 Englers.
