기체분사 LPG 연료공급시스템을 위한 저차압 타르휠터 개발

다국어 초록 (Multilingual Abstract)

Unsaturated hydrocarbons in domestic LPG fuel for vehicles form tar when vaporized. A LPG fuel also reacts with rubbers in the fuel supply system and forms tar. Tar is also formed by contaminants such as grease and compressor oil in LPG. In order to develop a tar filter, tar was collected from vehicle’s fuel supply system and analyze to investigate its composition. A reference tar consisting of Di-Octyl Phthalate, 2-(Methyl Amino)Ethanol and Methyl Palmitate, which represent the primary three components resulting, respectively, from the main sources of tar formation, was made. Tar filtration characteristics, through a basic study of tar vaporization and filtration test, were measured. And, a filtration media, using pressure drop and filtration performance test, was developed. A filter structure with low pressure resistance was deigned by numerical analysis. A prototype tar filter was developed, and its performance and pressure drop across were measured using engine as well as rig. The experimental results were compared with that of numerical. This study concludes that a tar filter for LPG gaseous injection system satisfying about 2kPa pressure drop across at WOT has been successfully developed.
