The utility model electronic ignition device is made up of Ignition Module and high-tension coil two parts; The mouth of Ignition Module links to each other with the primary winding of high-tension coil; The output primary of high-tension coil is chewed with the automobile high pressure and is linked to each other.Firing unit makes the output primary of high-tension coil produce many sparks of high frequency continuously, thereby ignites driving engine.
As shown in Figure 1, the utility model Ignition Module mainly is made of ignition signal generation circuit 1, dwell angle control circuit 2, the many spark circuits 3 of high frequency and protective circuit 4.The mouth of ignition signal generation circuit 1 links to each other with the signal input end of dwell angle control circuit 2; The control signal output ends of dwell angle control circuit 2 links to each other with the signal input end of the many spark circuits 3 of high frequency; The control signal output ends of the many spark circuits 3 of high frequency links to each other with the primary winding of high-tension coil.The signal input part of the utility model power-off protecting circuit 4 links to each other with the signal input end of dwell angle control circuit 2; The signal output part of power-off protecting circuit 4 links to each other with the signal input end of the many spark circuits 3 of high frequency; The output primary of high-tension coil is chewed with automobile engine high pressure and is linked to each other.
Ignition signal generation circuit 1 is made up of Hall switch K1, aerotron T1, optocoupler N1 and resistance R 1～R3.A resistance R 1 in parallel between the pin one of K1 (positive pole) and the pin 3; The pin 3 of K1 links to each other with the base stage of T1 by R2; The pin one of K1 (positive pole) links to each other with the collecting electrode of T1 by the light-emitting diode among R3, the N1; The pin 4 (negative pole) of the emitter of T1, the emitter of the aerotron among the N1 and K1 is ground connection all.Hall switch K1 is the hall effect type signal generator for ignition, and its pin 3 is constantly exported square-wave signal, and whether conducting and the shutoff of control T1 produce spark thereby control whole ignition device.
The utility model also can pass through the platinum contact controlled ignition, i.e. a platinum contact K2 in parallel between the pin two of Hall switch K1 and pin 4.
Dwell angle control circuit 2 mainly is made up of aerotron T2, source of stable pressure W1, comparator U1:A, U1:B and resistance, electric capacity.The base stage of T2 links to each other by the collecting electrode of the aerotron of light lotus root N1 in R4 and the ignition signal generation circuit 1, and the collecting electrode of T2 links to each other with the in-phase end of U1:A by source of stable pressure W1, resistance R 14, R15; The end of oppisite phase of U1:A links to each other with ground by resistance R 13; The mouth of U1:A links to each other with an integrating circuit (R9, R10, R14, R15, C3), and simultaneously, the mouth of U1:A links to each other with the end of oppisite phase of U1:B; The in-phase end of U1:B links to each other with the 12V power supply by R19, R21, R24, W2; The mouth of U1:B links to each other with the pin 3 of time meter U2.
Its principle of work is: when the pin 3 of Hall switch K1 is exported high level, and the T1 conducting, optocoupler N1 conducting, T2 turn-offs.Because the conducting of T1, N1, R27 is by short circuit, and the pin 4 of U2 is not imported, the not output of pin 3 of U2, and D10 does not have electric current.T2 turn-offs, and the current collection of T2 is high level very, and W1 has the electric current mistake, and the in-phase end of U1:A is a high level, and the mouth of U1:A is a high level; U2:B in-phase end link to each other with the 12V power supply, so the mouth of U2:B also is a high level, the T3 conducting, T4, T5, T6 turn-off, high-tension coil is output not.Because the mouth of U1:A links to each other with an integrating circuit (R9, R10, R14, R15, C3), the mouth of U1:A is a high level, integrating circuit begins integration, the end of oppisite phase voltage of U2:B begins to rise, and when U2:B end of oppisite phase voltage was higher than forward end voltage, U2:B turn-offed fast, T3 turn-offs, T4, T5, T6 conducting, the elementary energising of high-tension coil has spark output.Dwell angle control is finished, and promptly by the variation of integrating circuit control U2:B output end voltage, control conducting or the shutoff of T3～T6, thereby whether the control ignition coil produces spark.Regulate source of stable pressure R22 and change datum, change the size of dwell angle, when VREF (Voltage Reference) reduced, dwell angle strengthened, otherwise, reduce, realize dwell angle self-regulated (as shown in Figure 2).
As shown in Figure 2, in the prior art, ignition device becomes low level moment at high level, produces a spark; And being dwell angle, the utility model charging duration can adjust according to VREF (Voltage Reference); the current"on"time of control ignition coil primary winding; avoid high-tension coil to charge for a long time; reach the purpose of protection electronic ignition device and high-tension coil; save the energy, and, when ignition signal becomes low level by high level; when promptly discharging, the utility model can produce a plurality of sparks.
The many spark circuits 3 of high frequency are made up of time meter U2, aerotron T3～T6.Many sparks are to take place when Hall switch K1 output low level.When the K1 output low level, T1 turn-offs, the T2 conducting, and the current collection of T2 is low level very, and C3 is through D4, R16, R15 discharge; Another road of T2 collecting electrode makes the R24 short circuit, and R19 is a low level between R21, the R22, and U2: B is output as low level.Because this moment, T1 turn-offed, the pin 4 of U2 is a high level, a series of square-wave pulse signals of the pin of U2 3 outputs, this high-frequency pulse signal through diode D10, resistance R 23 to aerotron T3, T3～T6 exports high-frequency pulse current, makes the high-tension coil output primary form many sparks.
When to stall, dwell angle control circuit charging duration can not be oversize, otherwise the easy burn-out high-tension coil so the utility model has designed power-off protecting circuit 4 to stall, is made up of comparator U1:C, U1:D and Zener diode D8.When Hall switch K1 output high level, the T1 conducting, R17 is by optocoupler conducting ground connection, and the end of oppisite phase of U1:C is a low level, it is high level that in-phase end R7 obtains dividing potential drop from R5, R6, U1:C is output as high level, and begin integration through C2 this moment, and the U1:C output end voltage rises, 0.5 second after-current punctures the base stage of D8 to T3 through D7, R20, the T3 conducting, T4～T6 turn-offs, and the electric current in the high-tension coil primary winding progressively drops to zero.If automobile starts once more, when K1 was low level, T1, N1 turn-offed, the high and forward end voltage of U1:C end of oppisite phase voltage, and the U1:C mouth is a low voltage, and T3 turn-offs, and T4～T6 conducting recovers normal operation.When driving engine constantly turned round, zener diode D8 ceaselessly detected incoming signal, was power-off protection as long as shut down above 0.5 second.
When to stall, when Hall switch K1 was in low level, T1, N1 turn-offed, the T2 conducting; R8 is a low level, and U1:D carries out integration through the C1 comparator, and after voltage rose 0.5 second, the output voltage of U1:D punctured D8 through D2, R20; the T3 conducting, T4～T6 turn-offs, and finishes power-off protection.
The utility model high-tension coil is a kind of closed magnetic circuit, many sparks of high frequency formula high-tension coil, and its structure as shown in Figure 3.The primary winding 2 that is wrapped on the low pressure skeleton 1 is coupled by high-frequency core 3 and the intensity coil 5 that is wrapped on the intensity coil skeleton 4, and vacuum injection is in shell 6.The two ends of high-tension coil primary winding and the mouth of firing circuit (collecting electrode that is aerotron T6 links to each other with power supply), the two ends of high-tension coil intensity coil are chewed 7 with high pressure and are linked to each other.
Because the utility model adopts above design plan, has thoroughly eliminated the sooting of spark plug phenomenon, promote the gasoline economic combustion, the effect that promotes power, fuel saving and cleaning of off-gas is arranged; It also has quick start, the characteristic that igniting is not fallen to press in the time of can changing dwell angle control, parking automatic protection functions and galloping.
