Furthermore, by appropriate measures such as steaming and Nitrate the stop surface of the armature wear-resistant designed so that the stop surface during the entire Life of the fuel injector the same size and the operation of the Fuel injector is not affected.
  • Fuel injection valve is mainly the despite of optimized anchor stop surface still existing hydraulic damping force in the working gap when tightening of the anchor. Is an excitation current to the solenoid applied, the armature moves in the direction of the inner pole and displaces the between the inner pole and the anchor existing fuel. Due to friction and Inertia effects are the result of building a local Pressure field, which on the anchor stop surface a generates hydraulic force, which is against the direction of movement the anchor acts. This lengthens the opening and Metering times of the fuel injection valve.
