In the engine room area, there are many pipe lines of inflammable oil, and the exhaust pipes from an engine, a super-charger, too. If the leakage of the spray from the former pipe lines drops on and contacts with the high temperature surface of the heat insulator of the latter pipes, the oil will often self ignite and cause a fire.<BR>A purpose of this research is to confine the self ignition temperature within narrow limits for marine diesel gas oil and A heavy fuel oil, contain various kinds of hydrocarbon, in the case of dropping oil on high temperature surface. We reported the results of gas oil last year, for A heavy fuel oil, we took place the experiment, too. Comparing the experiment data of both oils, it is confirmed that gas oil cannot ignite certainly at temperature below 337 °C and A heavy fuel oil below 386 °C, on dropping volume 0.04cm<SUP>3</SUP>-0.3cm<SUP>3</SUP>. The boundary of self ignite and not self ignite for A heavy fuel oil is higher temperature than gas oil.
