Experimental study of vaporizing characteristics of a mini engine's "Г" type vaporizer was presented.The experiments were conducted under the atmospheric air pressure.The main factors of the vaporization rates including the Air/Fuel Ratio(AFR)

vaporizer inlet air temperature and the velocity of the airflow within the vaporizer were studied extensively.From the test results

it can be concluded that the AFR and the vaporizer inlet temperature are the important parameters to the fuel vaporization rates

and the increasing of the AFR and the inlet air temperature will cause an increase of the vaporization ratio.
