Patent ID: 7096855

Claim:
A device ( 1 ) for controlling the fuel quantity supplied to an internal combustion engine, with an injection nozzle ( 2 ) including a nozzle needle ( 5 ) and an actuator ( 6 ) for controlling the position of the nozzle needle ( 5 ), said device having a fuel supply line ( 3 ) for supplying fuel to the injection nozzle ( 2 ), a mass flow sensor ( 10 ) for the detection of injection parameters, and a control unit ( 4 ) in which control parameters for the actuator ( 6 ) are determined on the basis of the sensor data, said mass flow sensor being a miniaturized thin film sensor ( 10 ) capable of withstanding extreme operating conditions and arranged in the fuel supply line ( 3 ) to each fuel injection nozzle of the internal combustion engine for determining the fuel mass flow to each individual injector during fuel injection.
