In this study, plasma reformer technology with a LPG injector was investigated. It was developed with injection of LPG fuel and air in a region where the plasma discharge to make the thermal decomposition carbon fuel and to generate additional hydrogen. As a result of reforming test, when power is 70~100W supply, about HC 0.7% of the full reformed gas and hydrogen was generated from 1.2 to 1.5 %.

The liquid phase LPG injection (LPLi) system (the 3rd generation technology) has been considered as one of the most promising fuel supply systems for LPG vehicles. To investigate the reaction characteristics of LPG with rubber parts in LPLi system, various rubbers were tested. The results showed that the amount of residue from the cover rubber of a fuel pump was increased about 10 times after testing. Furthermore, the amount of sulfur and nitrogen species which are considered as main sources of deposit formation in LPLi fuel injectors were also found to be higher than those in original LPG fuel. In addition, these residues made the core parts of LPLi injector such as needle and nozzle, partially worn, which eventually causes leakage in LPLi injectors.

Until now LPG car has drived used to mixer and vaporizer. So LPG car always has problems back fire and when in the winter. LPG Car's Fuel consumption is rather than gasoline. But LPLi Fuel pump located in the fuel tank is directly injection in the engine. So Fuel consumption is better than LPG mixer system and result to reduced exhaust gas. In this paper to reduction of beating noise of LPLi(liquid phase LPG Injection) fuel pump. General speaking we know, beating noise is occur to near frequency each of pump. So we Modification of RPM through chang of amature turn number and area of dimension of the pump's body.

Recently, several LPG engines for heavy-duty vehicles have been developed, which can replace some diesel engines that are one of a main source for air pollution in urban area. As a preliminary study on the liquid phase LPG injection (hereafter LPLI) system applicable to a heavy duty LPG engine, the engine output and combustion performance were investigated with various combustion chambers and fuel compositions using a single cylinder engine equipped. Experimental results revealed that ellipse, double ellipse and nebula type combustion chamber made a more advantage in breaking swirl flow into small turbulence scale than bathtub type. Especially, performance of nebula type showed most highest efficiency and engine output under lean mixture conditions. An investigation fur various LPG fuel compositions was also carried out, and revealed that the case with 40% propane and 60% butane shows the lowest efficiency at stoichiometry, however, as the mixture became leaner its efficiency increased and became even higher for 100% propane case.

최근 LPG의 유통비용을 감소시켜 가격경쟁력을 제고하기 위한 움직임이 나타나고 있다. 도시외곽지역이나 특정사용시설을 중심으로 설치되는 LPG소형저장탱크의 보급을 통한 벌크공급시스템이 바로 그것이다. 따라서, 본고에서는 LPG벌크공급시스템에 대해 살펴보고자 한다.
