Description

Automobile high-energy ignition coil

The utility model relates to a kind of automobile igniter, especially automobile high-energy ignition coil.

Be used for the spark coil on the automobile at present, because ignition voltage is lower, can not provide high-octane continuously sparking, thereby make mixed gas incomplete combustion, discharge amount of exhaust gas is many, befouling environment.Chinese patent 90224033.1 discloses a kind of " automobile high-energy electronic igniter ", though this igniter has improved ignition voltage, but owing to be on the shell of former old-fashioned automobile ignition coil, a dual pressure controller to be installed, therefore, it not only easily makes former spark coil damage because of overload, and changed original attaching mode, make the user be difficult for accepting.

The purpose of this utility model provides a kind of automobile high-energy ignition coil, and it can improve ignition voltage, but direct substitution general point fire coil again, and do not change original attaching mode.

The purpose of this utility model is achieved in that being provided with high pressure output on the top of shell 3 chews 1, DC electrical source wiring pile 2 and triggering input wires stake 7, be characterized in being equipped with in shell 3 high-tension coil 4, insulator 5 and controller 6, the output terminal of high-tension coil is chewed 1 with high pressure output and is connected; Controller 6 exchanges output rectification circuit by self oscillations inverter circuit, trigger circuit, trigger circuit voltage stabilizer, inversion and middle voltage rise volt circuit is formed, the input end of trigger circuit is connected with triggering input wires stake 7, trigger circuit voltage stabilizer input end is connected with DC electrical source wiring pile 2, and the output terminal of middle voltage rise volt circuit is connected with the input end of high-tension coil 4.

The utility model is defeated next trigger signal from automobile platinum contact, directly enter trigger circuit, after trigger circuit triggers, the gate turnoff thyristor conducting, the frequency of gate turnoff thyristor conducting changes with external trigger signal frequency,, after exchanging the output rectification circuit rectification, inversion boosts from the high-frequency ac of self oscillations inverter circuit output by middle voltage rise volt circuit; In the moment of gate turnoff thyristor conducting, middle pressure is through the output of pulse output capacitance, and it is elementary to enter high-tension coil, by the continuous high-energy ignition high pressure of high-tension coil secondary induction output.

Adopt such scheme, but direct substitution general point fire coil not only, and the wiring mounting type of wiring mounting type and general point fire coil is identical; And can keep high-octane continuously sparking, ignition energy improves 2.5 times than general point fire coil, make mixed gaseous combustion complete, both increased power, saved gasoline, reduced toxic emission again, because the raising of ignition voltage, the electric current by the platinum contact no longer damages the platinum contact below the milliampere level, under the extremely low condition of ambient air temperature, the success of also once lighting a fire.

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

Embodiment of the present utility model is described with reference to the accompanying drawings.The utility model by high pressure output chew 1, DC electrical source wiring pile 2, shell 3, high-tension coil 4, insulator 5, controller 6 and trigger input wires stake 7 and form, have at the top end surface of shell 3 that high pressure output chews 1, DC electrical source wiring pile 2 and trigger input wires stake 7, be equipped with high-tension coil 4, insulator 5 and controller 6 in the shell 3, as shown in Figure 1.With reference to Fig. 2 as can be known, controller 6 is by triode BG1, BG2, resistance R 1-R4, the self oscillations inverter circuit that inductance coil L1-1-L1-4 constitutes, thick film trigger IC2, capacitor C 4, the trigger circuit that gate turnoff thyristor BCR constitutes, diode D3-D6, capacitor C 5, inductance coil L1-5 constitutes inversion and exchanges output rectification circuit, three terminal regulator IC1, capacitor C 1, C2, filter coil L3, trigger circuit voltage stabilizer and diode D1 that L4 constitutes, D2, capacitor C 3, the middle voltage rise volt circuit that inductance coil L2 constitutes is formed, 3 pin of the input end IC2 of trigger circuit are connected with triggering input wires stake 7, the L3 of trigger circuit voltage stabilizer, the common contact of C1 is connected with DC electrical source wiring pile 2, and the end of the output terminal C3 of middle voltage rise volt circuit is connected with the first wire-wound group B1-1 of the input end of high-tension coil 4.High-tension coil 4 is made up of transformer B1, and the end of the output terminal C3 of the middle voltage rise volt circuit in the elementary winding B1-1 of input end and the controller 6 is connected, and output terminal secondary windings B1-2 chews (1) with high pressure output and is connected.The complete machine working power is the same with the general point fire coil to be supplied with by automobile storage battery, DC electrical source wiring pile 2 by shell 3 tops offers controller 6, when static, whole in case the self oscillations inverter circuit work in the controller 6 of switching on, in L1-5, produce in the high frequency and press, exchange the output rectification circuit rectifying and wave-filtering by inversion and produce in the direct current and press, compress into the voltage rise volt circuit in the direct current after, arrive output capacitance C3 wait.In the time of dynamically, the triggering input wires stake 7 of trigger signal through shell 3 tops of being sent here by automobile starter enters trigger circuit, trigger gate turnoff thyristor BCR, after treating that BCR triggers, the output capacitance C3 of middle voltage rise volt circuit will produce certain energy pulses electric current, cause the elementary winding B1-1 of input end of high-tension coil B1 to produce a high-frequency ac induced potential, make the high pressure side B1-2 output continuous impulse high-energy ignition high pressure of high frequency coil B1, chew 1 output from the high pressure output on shell 3 tops.
