1 | Coil ignition | Transistor ignition |
1 | Contact breaker opens | Transistor closes |
2 | Ignition voltage is achieved (ignition voltage peak), sparking takes place |
3 | Directly after the sparking, the voltage drops abruptly to operational voltage level. |
4 | The spark-gap is no longer conductive, typical horizontal course of the operational voltage line in the coil ignition. | The spark-gap is no longer conductive, typical slanting course of the operational
voltage line in the transistor ignition. |
5 | The voltage swings out with subdued oscillations. (Drop-off process) |
6 | Contact breaker closes | Transistor switches through |
