Abstract

The invention provides a novel air flow control electromagnetic valve, namely, an electronic control carburetor electromagnetic valve, in a novel electronic control integral system of motor vehicle carburetor which can achieve the emission standard of Europe III. The outstanding feature of the electromagnetic valve is beautiful in appearance, remarkable shrinkage in size, convenient in mounting, high in sensitivity and fast in response speed, good in sealability, high in reliability; in addition the electromagnetic valve has obviously reduced working noise and has no general connection parts, and all the parts are connected by means of mutual embedding, welding and punching, and the electromagnetic valve is convenient to be added with an LED indicating lamp. The main parts of electromagnetic valve are: a drive coil and a frame (provided with a seal ring) thereof, a movable iron core and a seal ring thereof, a fixed iron core and a rubber gasket thereof, a soft iron shell, a soft iron gasket, a signal input wire, a resetting spring, a relevant connection wire and the like; if the LED indicating lamp is required to be mounted, a flexible circuit board, a patch light-emitting diode LED, a patch resistance and the like are further provided.

Description

technical field [0001] The invention relates to the technical field of an electronically controlled air supply system device for a motor vehicle engine, in particular to an airflow control solenoid valve with a new structure and connection method, which is suitable for indoor and outdoor applications. Background technique [0002] In the electronically controlled energy-saving purification system device (or electronic air supply system device) in automobiles and motorcycles, the air supply solenoid valve is the core executive component. Figure 5 In the block diagram of the working principle of the original electronic control air supply system device, the intake pipe of the valve seat of the air supply solenoid valve is connected to the air filter, the air outlet pipe is connected to the throttle between the carburetor and the engine, and the signal input line of the solenoid valve is connected to Controller ECU, the controller ECU in this system outputs a control signal to t...
