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 under the prerequisite that does not change former spark coil external structure, special high-tension coil and dual pressure controller are combined into one, its structure outline is: be provided with still on the top of shell that high pressure output is chewed, the former wiring pile of direct current and trigger the input wires stake, be equipped with high-tension coil, insulator and controller in the enclosure; Controller is by the self oscillations inverter circuit, trigger input circuit, trigger circuit, the trigger circuit voltage stabilizer, inversion high-frequency ac output circuit and rectification circuit, middle voltage rise volt circuit, gate turnoff thyristor and middle pressure pulse output capacitance are formed, wherein, gate turnoff thyristor is positioned at the end of trigger circuit, the trigger circuit voltage stabilizer was arranged before trigger circuit, trigger input circuit and self oscillations inverter circuit, inversion high-frequency ac output circuit and rectification circuit and middle voltage rise volt circuit are arranged after gate turnoff thyristor, press the pulse output capacitance between middle voltage rise volt circuit and high-tension coil are elementary, having.

After the utility model is received by trigger input circuit from the defeated next trigger signal in automobile platinum contact, directly enter trigger circuit, after trigger circuit triggers, can draw the transwitch conducting, the frequency of gate turnoff thyristor conducting changes with external trigger signal frequency,, after the rectification of high-frequency ac rectification circuit, boost 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.

Below in conjunction with drawings and Examples the utility model is further specified:

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

Fig. 2 is a circuit diagram of the present utility model.

As shown in Figure 1: the utility model by high pressure output chew 1, the former wiring pile 2 of direct current, shell 3, high-tension coil 4, insulator 5, controller 6 and trigger input wires stake 7 and form, its annexation is: have at the top end surface of shell 3 that high pressure output chews 1, a DC electrical source wiring pile 2 and trigger input wires stake 7, in shell 3, be equipped with high-tension coil 4, insulator 5 and controller 6, in conjunction with Fig. 2 as can be known, controller 6 is made up of following circuit: self oscillations inverter circuit (BG ₁, BG ₂, R ₁, R ₂, R ₃, R ₄, L _1-1, L _1-2, L _1-3, L _1-4), trigger input circuit (C ₁, D ₁); Trigger circuit (R ₅, R ₆, C ₄, C ₅, C ₆, C ₇); Trigger circuit voltage stabilizer (C ₂, C ₃, IC ₁); Inversion high-frequency ac output circuit and rectification circuit (D ₃, D ₄, D ₅, D ₆, L _1-5); Middle voltage rise volt circuit (D ₇, D ₈, C ₈, L ₂), gate turnoff thyristor BCR and middle pressure pulse output capacitance C ₉Form, wherein: gate turnoff thyristor BCR leaves the position end of trigger circuit, and trigger circuit voltage stabilizer, trigger input circuit and self oscillations inverter circuit were arranged before trigger circuit; Inversion is arranged with frequently exchanging output circuit and rectification circuit and middle voltage rise volt circuit after gate turnoff thyristor BCR; At middle voltage rise volt circuit and the elementary B of high-tension coil _1-1Between press pulse output capacitance C in having ₉

Further learn from Fig. 2: the self oscillations inverter circuit is positioned at before the trigger input circuit, and it exports high-frequency ac voltage, supplies rectification circuit and the required high-frequency ac of middle voltage rise volt circuit with this; Trigger input circuit is positioned at before the trigger circuit, provides trigger signal to trigger circuit, makes controllable silicon BCR conducting.Also can be learnt by Fig. 2: inversion high-frequency ac output circuit was rectification circuit (D before middle voltage rise volt circuit ₃, D ₄, D ₅, D ₆) high-frequency ac is provided; Middle voltage rise volt circuit is rectification circuit (D ₃, D ₄, D ₅, D ₆) direct current exported is upgraded to middle pressure, supplies high-tension coil required high-frequency pulse current with this.
