Development of a Turbine In-Tank Fuel Pump 870121

Considerations have been made on using turbine pumps as in-tank fuel pumps for electronic fuel injection systems (EFI). Flow channel dimension values, which had not been previously used for these types of pumps, were found to be very suitable for use as a fuel pump. The oil film visualization method was used to observe the flow pattern within the pump, and the results served to improve the flow channel shape. This contributed to designing a compact and efficient high-pressure fuel pump.
