Car spark plug coil feed having magnetic centre and secondary/primary wound coils with primary coil having lower area wound section with reduced capacitive coupling primary coil.

摘要

The coil feed system has a magnetic centre (10) and high voltage output connected to a spark plug (8). A secondary coil (6) is wound around the magnetic centre and a primary coil (2) wound around the secondary coil. the secondary coil has a first wound section (20) connected to the high voltage and having reduced capacitive coupling with the primary coil.
