排ガス管の断熱材表面に滴下した燃料油の自発火燃焼 Self-Ignition of Fuel Oil dropped on Surface of Heat Insulator of the Exhaust Pipe
In the engine room area. the leakage or the spray of inflammable oil from the pipe lines gives the cause of a fire. Oil will self-ignite by contact with the high temperature surface of the heat insulator.<BR>In regard to the self-ignition temperature, there are many data, obtained from the experiment under the closed, highly pressurized circumstances, but there are few data under the opened circumstances at atmospheric pressure.<BR>A purpose of this research is to confine the self-ignition temperature within narrow limits for marine diesel gas oil, contain various kinds of hydrocarbon, in the case of dropping oil on high temperature surface. As a result of an experiment, it is confirmed that gas oil ignite certainly at temperature above 398°C, not below 337°C, on dropping volume 0.04cm<SUP>3</SUP>-0.3cm<SUP>3</SUP>.
