How does a fuel shut off solenoid work?
The fuel shut-off valve contains two sets of coils: the holding coil and the pull-in coil. Power is supplied to the holding coil when the key is in the start position, preventing the valve core from being pulled in and shutting off the fuel supply. When the key is turned to the start position, power is supplied to the pull-in coil, pulling in the valve core, opening the fuel passage, and igniting the engine.
After releasing the key, the pull-in coil loses power. The holding coil remains energized, keeping the valve core in the pulled-in position, thereby keeping the fuel channel open and ensuring smooth engine operation. When the key is turned to the off position, the entire power supply, including the holding coil, shuts off. It causes the valve core to spring out and cut off the fuel supply, stopping the engine. This way, the fuel shut-off valve can fully perform its switching function.
Types of fuel shut off solenoid
Mechanical fuel shut off solenoid: Commonly found in small engines such as lawnmowers or generators. It controls the fuel flow and shuts down the engine by connecting to the control mechanism via a cable or linkage.
Pneumatic type: Powered by compressed air or other gases, typically used in industrial applications with pneumatic systems.
Hydraulically operated fuel shut off solenoid: Heavy equipment utilize this type of solenoid driven by hydraulic systems.
Vacuum type: It controls fuel flow based on vacuum pressure, commonly found in vehicles equipped with emission control systems.
Electric type: Used in automobiles, ships, and industrial engines, it opens or closes the fuel flow via electrical signals, allowing or cutting off fuel passage.
Common faults
- The fuel shut off valve overheats, leading to loss of function.
- When the key is turned to the start position, the engine ignites, but once released, the engine stops. This indicates a faulty solenoid coil.
Any of the above issues occur, it's wise to maintain or replacement to restore the equipment to normal operation. Could not find what you need? They may be in stock, welcome to contact us for details.
