Description

General gasoline engines inductance type igniter

Technical field

The utility model relates to a kind of special-purpose member of general gasoline engines, especially a kind of general gasoline engines inductance type igniter.

Background technique

At present, general gasoline engines inductance type igniter mostly is circuit structure shown in Figure 1 greatly, it is made up of igniter primary air L1, igniter secondary winding L2 and ignition controler, and the composite pipe igniting output circuit that the ignition control circuit that ignition controler is made of two triode Q1, Q2 usually and three triode Q3, Q4, Q5 constitute is formed.

Because the rotation of general gasoline engines flywheel, igniter primary air L1 induces an induction electromotive force, the ignition control circuit that this electromotive force is formed by resistance R 1, R2, R5, triode Q1, Q2, capacitor C1, control is ended by the conducting of the composite pipe igniting output circuit that resistance R 3, R4, triode Q3, Q4, Q5 form.When composite pipe by conducting become by the time, can produce a higher inductance voltage on the primary air L1; This higher inductance voltage on the primary air L1 raises this voltage by secondary winding L2, with this high voltage by the mixed gas in the spark ignitor cylinder, thereby the igniting of realization general gasoline engines.

Know by analysis, as long as IGNITION CONTROL triode Q2 can make firing circuit composite pipe (Q3, Q4, Q5) be become by conducting and end, and then can produce a high pressure at secondary winding by by becoming conducting, if this high pressure occurs, then finish accurate igniting in appropriate; If inappropriate the time, occur, then can influence the ignition energy and the ignition angle of igniter, and then influence the power and the discharging of motor.And traditional circuit can produce interference after igniter igniting, makes igniter produce vibration, makes the ignition energy and the angle instability of igniter, thereby allows the output power and the discharging variation of petrol engine; Simultaneously,, the heating value of components and parts in the ignition controler is raise, reduce operational safety, influence the working life of igniter because circuit itself has produced vibration.

Summary of the invention

Technical problem to be solved in the utility model is at the deficiencies in the prior art, a kind of general gasoline engines inductance type igniter is provided, it is simple in structure, the vibration of IGNITION CONTROL triode in the circuit in the time of can eliminating the igniter igniting, the working life of the ignition energy of raising and point of safes firearm and angle, prolongation igniter.

The utility model has adopted such technological scheme, a kind of general gasoline engines inductance type igniter, include the igniter primary air, igniter secondary winding and ignition controler, this ignition controler is by first triode, ignition control circuit and the 3rd triode that the IGNITION CONTROL triode constitutes, the 4th triode, the composite pipe igniting output circuit that the 5th triode constitutes is formed, it is characterized in that in aforementioned ignition controler, the output terminal of the IGNITION CONTROL triode of ignition control circuit is connected to a capacitor, and the two ends of this capacitor are connected with the collector and emitter of aforementioned IGNITION CONTROL triode respectively.

The general gasoline engines inductance type igniter that provides by the utility model is owing to connected a capacitor, the vibration of IGNITION CONTROL triode in the circuit when having solved the igniter igniting between the emitter and collector of the IGNITION CONTROL triode of ignition controler; After igniter was implemented igniting, the interference of generation was by the capacitor elimination, make igniter reliably, igniting accurately, improve and the ignition energy of point of safes firearm the working life of prolongation igniter.The utility model is simple in structure, the vibration of IGNITION CONTROL triode in the circuit when having eliminated the igniter igniting, improved and stablized igniter ignition energy, prolonged working life of igniter.
