Benzine's octane number is more than 100,but they say, it is apt to knock on commercial engines. More than ten years ago, benzene was blended in gasoline, but not now. We tried to make these combustion characteristics clear, and compared the benzene, toluene, xylene and gasoline with each others, in 1944. This experiment was operated by a air-cooled single cylinder testing engine. As testing fuel ; pure benzene, toluene and xylene were mixed with 72-octane gasoline free from aromatic compound, and their octane numbers were 92. And the 72-octane gasoline containing lead-liquid was added to make its octane number 92. We obtained knocking zones, out-put courves, and other characteristics of these fuels. Then we found these aromatic compounds could be used as high class internal combustion engine fuel, especialy at low intake mixture temperature, and toluene, was the best in these aromatic fuels.
