CE822 Triplex Pump – High Pressure Version
Triplex Pump – High Flow Version

Triplex Metering Fuel Pump

The triplex metering fuel pump represents a substantial step forward for EFI technology in small engines. The triplex provides high-pressure regulated fuel delivery of particular application to heavy fuel and gasoline engines. Its unique phased three-piston design, combined with an integrated control system, gives very precise regulation of fuel delivery across a wide range of pressures.

    • Description
    • Additional information

    The triplex is an enabling technology for heavy fuel engines, providing high pressure fuel that is able to be finely atomized using Currawong’s unique atomization technology.

    A special feature of the pump is built-in precision measuring of fuel flow without having to rely on separate meters and other non-design-intent hardware. This feature can be used throughout system development, and is particularly useful when used with a dynamometer as Brake Specific Fuel Consumption can be easily calculated in real time.

    Principle Features

    • Self priming ability
    • Integrated electronics that provide precise fuel pressure and flow metering
    • Three phased pumping cylinders to provide a smooth fuel delivery without the use of a fuel accumulator or mechanical regulator
    • Fully compatible with the Currawong ECU and with other ECUs
    • Very low power consumption
    • High pressure fuel delivery
    • Entirely compatible with Cloud Cap Technology’s avionics as well as with other avionics systems
    • Able to be deployed as a flow metering pump with < 1% error

    The system can be used on its own, or can be used in conjunction with the Currawong ECU and other parts of integrated EFI systems.

    An example of a typical configuration (that may be altered by changing the motor/gearhead configuration) is shown. The following figures are for a motor fitted with a 28:1 gearhead:

    • Voltage: 15V
    • Current: 100mA
    • Pressure: 8 bar
    • Pressure Regulation: within 2%
    • Flow regulation: within 1%
    • Flow Rate: 36 g/min *

    * Flow rates up to 400 g/min (50 Hp) are in development
