Influence of Mixture Heating on the Vaporization of Fuel Oil in the Suction Pipe of Kerosene Engine (Part 2)

Abstract

By motoring a kerosene engine mixture being sucked, the rate of vaporization of gas oil in the horizontal suction pipe has been studied varying the air-fuel ratio and the wall temperature of heater. Results of motoring test have been compared with results of blower-test, which was performed under equivalent air velocity and the same conditions as motoring test. Thermal efficiency of vaporization has been proposed as standard of effective vaporization in the suction pipe. For vaporization of fuel oil in the suction pipe under continuous air flow, the lower air velocity, the less fuel flow, and the more heat supply, the higher thermal efficiency of vaporization has been obtained.
