A flammable material such as fuel oil or lubricating oil can often be the cause of a ship's fire disaster. There have been many studies of pure materials, such as benzene or alcohol, but very little of practical use is known about self ignition phenomena of fuel oil and lubricating oil, as far as the authors are aware. We examined the ignition characteristics of gas oil, marine diesel oil, heavy fuel oil, and lubricating oil, and reported the characteristics of these flammable materials. In this study, especially in the part using turbine oil, we tested by the same method used previously. Because new information was found, we report the new portions.
