This study has mainly focused on the development of turbine type LPLi pump. The flow rate of turbine pump was examined with various fuel blends of LPG. The experimental results of flow rate and fuel injection quantity of turbine type fuel pump have equivalent or better performance using summer season LPG fuel compared to BLDC one. However, the flow rate of turbine type pump decreased as the proportion of propane content in LPG fuel increased. The cause of flow drop was thought as the cavitations phenomena at high speed impeller component. Finally, the noisy characteristics and durability performance of turbine pump were tested. The hot start delay of LPLi engine was assessed with various composition ratio of LPG. The engine starting and pressure settling time of turbine pump showed equivalent performance to those of BLDC one.
