GF40U2-FI

  • A starter generator system is newly installed based on the 4-stroke single-cylinder 40cc engine "GF40U-FI" with an electronically controlled fuel injection device.
  • A 200W class generator is mounted on the rear of the engine aligned with crank shaft and operates as a starter at start-up.
  • The ECU (engine control unit) equipped with a 32-bit CPU performs optimal management for the engine based on the throttle opening, engine speed, crank angle, atmospheric pressure, and cylinder head temperature.
  • The ECU provides the parameter information of the ECU such as engine speed, cylinder head temperature, throttle opening, and atmospheric pressure to the outside in real time by serial communication and CAN.
