The present invention is described in further detail below:
The ignition unit is of an existing structure, and the working principle of the ignition unit is as follows:
when the magneto works, the primary coil L1 induces an electromotive force, the waveform is shown in fig. 3, when the induced electromotive force is in a negative half period, the voltage division effect of the resistor R1 and the resistor R2 makes the triode Q2 not be conducted before the triode Q3 is conducted (by setting the resistance values of the resistor R1 and the resistor R2), and after the triode Q3 is conducted, the Q4 and the Q5 are conducted; after Q5 is turned on, the induced electromotive force induced by the primary coil L1 forms a loop through the primary coil L1, the resistor R5, and the CE pole of the triode Q5.
At this time, the voltage drop across the resistor R5 increases with the increase of the current, when the voltage drop across the resistor R5 is greater than the on voltage of Q1, the transistor Q1 is turned on to charge C1, at this time, the circuit formed by connecting Q1 and the capacitor in series is equivalent to connecting a resistor in parallel to R1, the transistor Q2 is turned off, as the voltage across the capacitor C1 increases, the transistor Q1 is turned off, the voltage drop across the resistor R1 increases to enable the transistor Q2 to be turned on, Q2 is turned on to enable Q3, Q4 and Q5 to be turned off, at this time, a voltage of several hundred volts is self-induced in the primary coil L1, the voltage is boosted by the secondary coil L2, and a high voltage of 10KV or more is output to the spark plug to ignite the mixture in the engine cylinder.
The principle of the ignition control unit of the present invention:
When a fault occurs, an external controller (which is not described in detail in the prior art) inputs a high level to the base electrode of the triode Q6, the triode Q6 is conducted at the moment, negative voltage induced by the primary coil L1 forms a loop through the BE pole of the triode Q4, the diode D3 and the CE pole of the triode Q6, the triode Q4 and the triode Q5 are conducted at the moment, the Q4 and the Q5 are not turned off, so that no self-induction voltage is output on the primary coil L1, and the gasoline engine is not ignited;
When the external controller inputs a low level, the triode Q6 is cut off, and the igniter realizes ignition according to the control principle of the ignition unit.
Delay flameout:
When the ignition control input end fails to output due to open circuit and failure of the protection device caused by falling off, breakage and the like, the ignition control end has no signal, and the voltage VCC charges C3 through the resistor R7. When the voltage UC3 at two ends of the capacitor C3 is more than or equal to the conducting voltage UT Q7 of the MOS transistor Q7, the MOS transistor Q7 is conducted, after the MOS transistor Q7 is conducted, the voltage VCC forms a loop through the resistor R8, the MOS transistor Q7 and the BE of the Q6, and the triode Q6 is conducted; after Q6 is conducted, the triodes Q4 and Q5 are kept on, so that the igniter does not ignite; wherein the delay flameout time is determined by the charge time of the capacitor C3; through the delayed flameout function of the application, when the engine stops due to faults, a user runs through to check and usually restarts the engine, if the engine is started normally, the engine stops after a period of time delay, and the user can judge that the engine is normal and stops due to other fault reasons.
And (3) quick recovery: when the engine is stopped due to the falling off of a control line, breakage or alarm fault, the charge stored on the capacitor C2 is discharged rapidly through the BE junction of D2-R8-Q7-Q6, so that the engine can BE started immediately after the engine is stopped.
