DC12Voltage 9mm Hole LPG/CNG Injector Rail Automotive Solenoid Coils In Autogas System

Injector rail solenoid valve for an injector, comprising a valve body, a valve core, a LPG/CNG injector rail solenoid coil and an armature assembly, the armature assembly comprising an armature and a ball engaged with the armature, the valve core being located in a cavity of the valve body, the valve core comprising a valve core And the solenoid coil wound at the corresponding position of the spool magnetic pole, the armature and the valve core magnetic pole clearance fit, characterized in that the armature is connected to the valve body on the side deviated from the center thereof, and the valve body is on the other side deviating from the center thereof The elastic connection causes the armature to generate a non-parallel movement after the solenoid valve is de-energized, thereby applying an eccentric torque to the ball to bias it on the valve seat.

Structure and working principle of common rail injector with DC24V LPG/CNG solenoid coils:
Let us talk about the structure and working principle of common rail injectors for common faults in injectors:

1. Initial state
When the injector solenoid valve is not triggered, the injector is closed, the drain hole is also closed, and the small spring presses the armature ball valve against the orifice to form a common rail high pressure in the valve control chamber. Similarly, a common rail high pressure is also formed in the injector, and the common rail pressure balances the pressure of the control plunger section and the pressure of the nozzle spring with the opening force of the high pressure fuel on the tapered surface of the needle valve, so that the needle valve remains closed. status.

2. Fuel injection start state
When the solenoid valve is triggered, the armature opens the drain hole, the fuel flows from the valve control chamber to the upper cavity, and returns from the cavity to the oil tank through the oil return pipe, so that the control chamber pressure is lowered; the control chamber pressure is reduced, and the pressure is reduced. The force acting on the control plunger, at which point the nozzle needle is opened and the injector begins to inject oil.

3. End of injection
Once the solenoid valve is powered off, the force of the small spring will not be triggered, and the solenoid valve will be pressed down. The ball valve will close the drain hole. After the drain hole is closed, the fuel will enter the control chamber from the oil inlet hole to establish the oil pressure. This high pressure is controlled. On the cross section of the plunger, the rail pressure plus the spring force is greater than the pressure on the conical surface of the needle valve, causing the nozzle needle to close.
