Background technique
In recent years, New Electronic Control Diesel Fuel Injection System is considered to improve jet pressure, optimizes diesel engine combustion, reduces discharging and keep the good fuel economy of motor to have the technological scheme of potentiality.The pulsed electronic diesel injection system of time control is system core parts---the high speed powerful solenoid valve that adds a control oil mass and injection timing in traditional mechanical type diesel injection system, to replace traditional mechanical adjustment mechanism.The core component of high speed powerful solenoid valve is an electromagnet.Referring to Chinese utility model patent " high speed powerful electromagnetic control valve " (patent No.: ZL 97202929.1), there is following major defect in the electromagnet that uses in this solenoid electric valve: (1) electromagnet adopts circular multipole monolithic construction, inductance is bigger, electric current is longer building-up time, and electromagnetic force is set up rapid inadequately; (2) active force of electromagnet generation is big inadequately; (3) electromagnetic coil is wound on each iron core pole by an enameled cable integral body, and coil adopts series-mode frame, and the coil rotation direction on the adjacent pole is opposite, and coiling is trouble very.
The model utility content
The purpose of this utility model and task are designs and make a kind of quick response electromagnet that uses in the pulsed electronic diesel injection systems of time control, make the active force that it is simple in structure, speed of response fast, produce big.
Above-mentioned purpose and task are achieved through the following technical solutions: a kind of quick response electromagnet that uses in electronic diesel injection system, mainly comprise electromagnetic core, winding, wiring terminal and mould shell, it is characterized in that: described electromagnetic core is to be formed by stacking by a plurality of three dentation core laminations, and coil forms winding on the center tooth of electromagnetic core.
Above-mentioned three dentation core lamination thickness are 0.1～1mm.
For electromagnetic core after the injection moulding does not produce looseningly with moulding shell, be provided with the injection moulding antiratchetting groove in the three dentation core laminations outsides.
The utility model compared with prior art has the following advantages and beneficial effect: 1. the inductance of electromagnet is little, and electric current is set up process and shortened, and electromagnetic force is set up rapidly, and speed of response is fast; 2. this electromagnet structure is simple, and coiling can conveniently be applied to the pulsed electronic diesel injection system of all kinds of time controls easily; 3. the eddy current loss of electromagnet is little, and heating value is little, the capacity usage ratio height.

Embodiment
Below in conjunction with description of drawings theory structure of the present utility model and most preferred embodiment:
The utility model is mainly moulded shell 1 by electromagnetic core 3, wiring terminal 2, coil winding 4 and injection moulding and is formed; Electromagnetic core 3 adopts three dentation structures (being E shape structure), is formed by stacking by a plurality of core laminations 5, and its size can be determined according to the requirement of use occasion; For electromagnetic core after the injection moulding 3 does not produce looseningly with moulding shell 1, be provided with injection moulding antiratchetting groove 6 in three dentation core laminations, 5 outsides, this antiratchetting groove can adopt circular arc and swallowtail-shaped structure or other structure; Enameled cable forms winding 4 on the center tooth of electromagnetic core 3; Shell 1 shape is moulded in injection moulding and size can be according to the specific design that requires of use occasion.
In the utility model, the iron core of electromagnet has adopted the sheet type structure 5 of E shape, and sheet thickness is very little, generally between 0.1～1mm.This structure can reduce the electromagnet inductance greatly, shortens the building-up time of electric current in the electromagnetic coil, promptly accelerates the generation of electromagnetic force.In this most preferred embodiment, the sheet thickness of employing is 0.2mm, and the boundary dimension of electromagnetic core is length * wide * height=27 * 19 * 22mm
3When VDC was 24V, can adjust the distance in the 1.4ms armature at 0.3mm place of electromagnet produced the electromagnetic force of 320N.
The utility model is suitable for the pulsed electronic diesel injection system of all kinds of time controls, as electronic control dispensing pump system, automatically controlled pump-pipe-valve-mouth system, electronically controlled unit pump system and electrically-controlled pump nozzle system, it is little of three, 40 kilowatts to be applied to power, arrives the diesel engine of several megawatts greatly.
