Spark ignition system having a capacitive discharge system and a magnetic core-coil assembly |
摘要 |
A spark ignition system for an internal combustion engine has a capacitive discharge (CD) system connected to a coil-per-plug (CCP) magnetic core-coil assembly. The spark ignition system is connected to a spark plug and is adapted to initiate an ignition wherein a spark is produced across the gap of the spark plug. The spark ignition system includes a magnetic core-coil assembly having an amorphous metal magnetic core, a primary coil and a secondary coil for a high voltage output to be fed to a spark plug. The CD system is charged and rapidly discharged through the primary coil of the magnetic core-coil assembly using a silicon controlled rectifier (SCR) as the switch. Operation of the SCR is controlled by circuitry that controls the firing of the spark ignition system. The magnetic core-coil assembly acts as a pulse transformer, so that voltage across its secondary coil is related to the turns ratio of secondary to primary.
