GF07.61-P-3018BK ME-SFI Safety Fuel Shutoff - Function







The safety fuel shutoff has the following tasks:
- In the event of mechanical faults at the throttle valve actuator, the engine speed is limited to approx. 1400 to 1800 rpm by cutting in and out the fuel injection valves (strong surging engine running).
- It interrupts fuel pump actuation if the TNA engine speed signal is missing.
- It shuts off the fuel pump when the airbags are activated (head-on collision) through the ME control unit receiving a crash signal from the airbag control unit. The fuel valves are actuated briefly to reduce the pressure in the fuel system.
