Experiments on a Heat Plug

抄録

In the cylinder injection engine, for example, the Texaco Combustion Engine, the continuous ignition source was required in order to get knock-free combustion with the stationary flame front, as already reported in the previous paper⁽1). An electrically heated hot spot in the combustion chamber, named "Heat Plug", was utilized as a continuous ignition source. Following experiments-on the relations between temperature of heated surface and ignition lags of fuels, photographic study of ignition and also combustion by a heat plug-were made. In addition, the performances of the two-stroke-cycle gasoline engine ignited by the heat plug were measured, running with gasoline and Diesel light oil.
