What’s the Solenoid Valve?
The Bosch diesel injector solenoid valve is a vital component consisting of the solenoid valve itself, solenoid spring, armature shaft, armature disc, and return spring. The solenoid valve is controlled by the engine’s electronic control unit (ECU) using a PWM signal with a specific duty cycle. It operates at high voltage (close to 100V) to enable rapid lifting of the armature shaft. For maintaining current under a standard power supply voltage of 24V, a lower voltage is typically used to conserve energy.
The Solenoid Valve Working Principles:
- When the solenoid valve is not energized, the armature shaft, under the force of the spring, presses the ball seat and ball against the return flow throttle orifice of the control valve, sealing the orifice and preventing fuel injection.
- When the solenoid valve is energized, the armature shaft overcomes the spring force, slightly lifting the ball seat and ball to open the return flow throttle orifice. This reduces the pressure in the nozzle needle control chamber, causing the needle to rise and allowing fuel to spray into the combustion chamber through the nozzle spray holes.
