In this paper developed LPLi (liquid phase LPG Injection) fuel. 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. <br/> So Fuel consumption is better than LPG mixer system and result to reduced exhaust gas.<br/> LPLi car's fuel rail pressure is 5bar. Cause fuel pump has to operate the pressure. And 2 stage series connection for gasoline pump. All this while LPLi pump has developed is success include in basic function and normal temperature.

In this paper developed LPLi(liquid phase LPG Injection) fuel pump. 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.<br/> In addition to LPLi pump also used to turbine gasoline pump. Essentially come up to impeller noise. In this study changed steel case to rubber case. Because of LPLi pump is outbreak resonance between steel case and impeller frequency. In result noise is down till 7㏈ in the bombe.

In this study is automatic measurement equipment of fuel pump for automobile. Especially this equipment is used mass product line. Until now fuel pump has done sensuous test by worker. So object test was impossible. But this equipment is able to examine more objective test. We have considered DC motor 's character influence on noise. This program can check balancing defect, bearing defect, brush and commutator defect, impeller defect so on. From now no we will develop equipment vibration, noise and pulsation at once.
