Description
Technical Field
[0001] The utility model relates to the technical field of fuel injection nozzle cleaning, in particular to a canning device for a fuel injection nozzle cleaning agent for an engine. Background Art
[0002] The fuel injector used in today's cars is actually a simple solenoid valve. When the electromagnetic coil is energized, suction is generated, the needle valve is sucked up, the spray hole is opened, and the fuel is sprayed out at high speed through the annular gap between the needle at the head of the needle valve and the spray hole, forming a mist, which is conducive to complete combustion. In the past, the fuel injectors used in diesel engines were mechanically controlled. The mechanical diesel nozzle works by controlling precision parts (needle valve, needle valve body). The nozzle part is one of the three major precision parts of traditional diesel engines. The gasoline engine nozzle is part of the gasoline engine's electronic control system, replacing the carburetor of the carburetor-type gasoline engine.
[0003] Filling cleaning agent is required for cleaning the fuel injector. Generally, the cleaning agent is first loaded into the tank body, and a certain pressure of gas is input and sealed. The gas easily overflows from the nozzle, causing the pressure difference between the inside and outside of the cleaning tank to decrease, and the cleaning tank cannot be used. After the cleaning agent is used up, it is difficult to recycle the tank body, resulting in a waste of resources. When cleaning the general fuel injector, an external device is required to suck up the needle valve. The process is relatively cumbersome and wastes a lot of time, which seriously affects the cleaning efficiency of the fuel injector. In view of the above problems, a canning device for engine fuel injector cleaning agent is proposed to solve them. Utility Model Content
