GB Breaker Ave

This allowed to ensure system availability in terms of exposure to power circuits transients with amplitudes of up to 120 V. The new system is also a three-time mode sparking during starting of the engine starter (not reusable, such as in systems 'Start', 'Iskra-3', BESZ-1, namely three times). The fact that the regime mnogokratnoge sparking, ie, a mode in which the sparking continues for as long as contact breaker is open, sometimes not only does not help, but, conversely, makes it difficult to start the motor, stopping the rotation of its shaft. If the gap in the breaker cam shaft is large or has a gap in relation to talking about any particular gap, one can not, those sparking the system continues and if the distributor rotor is rotated by 45 or more relative to the start of contact opening the breaker. As a result, the spark discharge occurs not only in the ground, but in the course of the next rotation of the rotor cylinder, which at that time had just begun the compression stroke.

In this case there are 'backlash', stop rotation of the motor shaft. This creates serious operational inconvenience. First, it extends an additional requirement to reduce the gap in the breaker regarding recommended by the vehicle manufacturer and Secondly, the system can not be used on worn-out engines, where usually the distributor shaft play is great and where the system is especially needed. Fig. 7. The electrical circuit of a capacitor ignition system with a pulse energy storage: a – Thyristor optocouplers, b – to the replacement transistor optocoupler in – with germanium transistors in the power manievymi manner described in the design of this deficiency is eliminated. In the start-start system provides three spark after each contact opening the breaker.

Sparks comes to an end long before the rotor is rotated by 45 . To facilitate the starting of the engine the same, as shown, a three-fold Sparks is not worse than repeated. The system provides easy switching to a classic and is inversely pesredstvom termination plug. The electrical schematic is shown in Fig. 7. The system consists of electronic module and connector DL x2, HZ ustrvystva switch from conventional to electronic ignition, as well as full-time elements – ignition coil circuit, the ignition switch to the OT switch starter TSA, battery and GB Breaker Ave. The electronic unit has the following main components: a voltage converter bortseti in high voltage charge on the capacitor-Cumulative containing the power transistor to transistor V29, V30, V32 and diodes V24, V25, V26, thyristor V22, transformer T1 mater, the rectifier V33, C14 and the storage capacitor device stabilization in optocouplers V23; the thyristor switch and a transformer T2, V37, connects the storage capacitor C14 is charged to primary winding coils for wl-BB bandits at the time of the breaker contact opening; bit diodes V35, V36, ensuring full utilization of the energy storage capacitor for sparking; cascade debounce on transistors, V20, V21; sparking a cascade of three times when starting the engine, consisting of two triggers on the transistors VI, V5 and V6, V9 and four transistor switches – V10, Vll, V13, V14.
