The degree of vaporization of fuel oil in the suction pipe has been studied experimentally using gas oil in case of mixture heating. The experiment has been performed in a horizontal suction pipe under continuous air stream varying air-fuel ratio, air velocity, degree of heating, and throttle-opening. On condition that heat supply was constant, the following results were obtained : The rate of vaporization has been increased by larger air-fuel ratio under constant air velocity and lower air velocity under constant air-fuel ratio. In case of non-heating, the rate of vaporization was only few percent, but at the wall temperature of 200℃, the rate of vaporization was increased to about 30 percent. In narrow thro ttle-opening, a large percentage of fuel oil flowing along the pipe wall, the rate of vaporization being lowered remarkably, then heating of mixture (pipe-wall) has become more effective.
