摘要

摘要: 为研究微小型发动机中的Г型蒸发管的蒸发性能,在进口空气为常压条件下,对微小尺寸Г型蒸发管的蒸发性能进行了试验研究。研究了气油比、进口空气温度以及蒸发管内空气流速的变化对蒸发管燃油蒸发率的影响。试验结果表明,气油比和蒸发管空气进口温度是蒸发率的主要影响因素,蒸发管内空气速度影响并不显著,气油比的增大和空气进口温度的增大都会导致燃油蒸发率的增大。

Abstract: 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.
