Circuit operation principle is as follows：
Ignition coil B1 primary coil L1 (i.e. Magnetor stator) induces one group of EMF pulse waveform (waveform first
See Fig. 2)；When L1 induced electromotive force negative pulses forward position is arrived, because resistance R1 and resistance R2 partial pressure effect make triode Q2 not
It can be turned on prior to triode Q3, after triode Q3 conductings, triode Q4, triode Q5 conducting.After triode Q5 conductings, ignition lead
C, E pole of the induced electromotive force through primary coil L1, resistance R5, triode Q5 that circle B1 primary coil L1 is induced forms loop
Conducting.
Then the pressure drop on resistance R5 increases with the increase of electric current, when the pressure drop that the pressure drop on R5 is more than C1 exceedes
During 0.7V triode Q1 conducting to the first electric capacity C1 charging (now triode Q1 and the first electric capacity connect the circuit to be formed equivalent to
A resistance in parallel on R1), triode Q2 ends, and voltage increases as pulse front edge rises on the first electric capacity C1, senses
Electromotive force to triode Q1 after peak value of pulse B pole tensions are less than voltage on the first electric capacity C1, and triode Q1 cut-offs (are filled on C1
Electricity discharged through triode Q1, Q2), the now pressure drop on resistance R2 be also added to can make triode Q2 turn on, three poles

The present embodiment band stop working auto-lock function inductance type ignitor, the operation principle of its ignition control circuit with it is traditional
Circuit operation principle is identical.
The inductance type ignitor of the flame-out auto-lock function of the present embodiment band, the operation principle of its flame-out latching circuit is as follows：
1st, when gasoline engine, which runs well, needs flame-out shut down, flameout switch S1 (S1 short circuits), primary coil are manually pressed
L1 induced electromotive forces " A points " pulse is timing, through the first diode D1, the second electric capacity C2, the second diode D2, flameout switch S1
Charged to the second electric capacity C2 in loop.
After primary coil L1 induced electromotive forces " A points " positive pulse, the electricity that the second electric capacity C2 fills through the 6th resistance R6,
6th triode Q6, the 9th resistance R9 loops are discharged, and are added B, E pole to bias to the 6th triode Q6, are made the 6th triode Q6
Maintain B, E pole positively biased state.When primary coil L1 induced electromotive forces " A points " pulse is bears, the 6th triode Q6 is turned on, and the 4th
Triode Q4, the 5th triode Q5 are turned on therewith, and the electromotive force that primary coil L1 is produced is released through the 5th triode Q5 formation loop
Bleed off, ignition control circuit failure reaches extinction function.
The electricity that second electric capacity C2 fills is discharged through the 7th triode Q7, the 7th resistance R7 loops simultaneously, to the 7th
Triode Q7 adds B, E pole to bias, and the 7th triode Q7 is kept B, E pole positively biased state.
2nd, when manually unclamping flameout switch S1 (S1 open circuits), in the state of gasoline engine does not stop completely, primary coil L1
Continue generation electromotive force to continue to be loaded into control loop, because the electricity release filled on the second electric capacity C2 needs a timing
Between, the 6th triode Q6 conductings are continued to, the 4th triode Q4, the 5th triode Q5 conducting maintain ignition control circuit to lose
Effect.
3rd, when petrol engine continuous running is to making the next induced electromotive force negative pulse of primary coil arrive, " A points " arteries and veins
Rush as timing, due to the electricity release that the second electric capacity C2 fills, add B, E pole to bias to the 7th triode Q7, make the 7th triode
Q7 keeps B, E pole positively biased state, the 7th triode Q7 conductings.The 8th triode Q8 is set to turn on therewith by the 8th resistance R8.Just
Induced electromotive force on level coil L1 is through the first diode D1, the second electric capacity C2, the 8th triode Q8, the 3rd diode D3 loops
Electricity is supplemented to the second electric capacity C2 again, each cycle supplements an electricity to C2 electric capacity.Gasoline engine is not exclusively shut down, the second electricity
Holding electricity on C2 would not release, and form self-marketing loop, reach flame-out auto-lock function, it is ensured that gasoline after crawl flameout switch S1
Machine can just be stopped completely, will not error starting.
As the improvement to the present embodiment, the inductance type ignitor of the flame-out auto-lock function of the present embodiment band is also included with stopping working
The engine oil sensor of switch in parallel, in the state of machine oil is not lacked, engine oil sensor is in normally open, when lacking machine oil,
Engine oil sensor is turned on, and this improvement make it that when engine motor oil is alarmed blowout protection can be realized.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to skill of the invention
Art scheme is modified or equivalent substitution, and without departing from the objective and scope of technical solution of the present invention, it all should cover at this
Among the right of invention.
