In the technical solution adopted in this embodiment, a needle valve assembly is provided in the valve chamber 11 of the valve housing 10, and the needle valve is slidable in the valve chamber 11 in the axial direction of the valve housing 10. Meanwhile, a valve seat 20 is arranged at one end of the valve sleeve 10, and an oil injection port 21 communicated with the valve cavity 11 is arranged on the valve seat 20. The oil injection port 21 can be opened or closed by sliding the needle valve assembly.

After the power is off, the magnetic force disappears, and the needle valve assembly moves towards the direction approaching the oil injection port 21 under the elastic force of the elastic member 53. Alternatively, the elastic member 53 is a spring.

2. The methanol fuel injector of claim 1 wherein said armature includes first and second opposed sides, each of said first and second sides being slidably coupled to a wall of said valve chamber, said corrosion-resistant structure being disposed on said first and second sides.
3. The methanol fuel injector of claim 2 wherein the armature further comprises a top surface and a bottom surface, the first side surface, the second side surface, the top surface, and the bottom surface collectively forming an outer peripheral surface of the armature, the corrosion resistant structure being provided on the top surface and/or the bottom surface.
4. A methanol injector as in any of claims 1-3 wherein the corrosion resistant structure comprises any of a diamond-like coating, a thermal spray coating, and a nitriding coating.
5. The methanol fuel injector of claim 1 wherein the valve seat is further provided with a seal bore in communication with the fuel injection port, the needle valve assembly comprising:
the valve rod is arranged in the valve cavity in a sliding manner, and the armature is arranged at one end of the valve rod, which is away from the oil injection port; a kind of electronic device with high-pressure air-conditioning system
And the valve ball is arranged at one end of the valve rod, which faces the oil injection port, and the valve ball moves synchronously along with the valve rod and is matched with the sealing hole to close the oil injection port.
6. The methanol injector of claim 5, wherein a surface of the valve ball facing the oil injection port is provided with a reflective surface for reflecting gas.
7. The methanol fuel injector as in claim 5, wherein the valve stem is provided with a plurality of outlets, the outlets being provided in a circumferential direction of the valve stem, the outlets being in different directions and being perpendicular to an axial direction of the valve stem.
8. The methanol fuel injector of claim 1 wherein the electromagnetic drive assembly further comprises: and the elastic piece is connected with the armature and the electromagnetic coil.
9. An engine comprising a methanol injector as claimed in any one of claims 1 to 8.
10. A vehicle comprising the engine of claim 9.
