Definition
Noun: A component in an internal combustion engine's ignition system. It is a type of induction coil that transforms the low-voltage direct current (DC) from the vehicle's battery into the high-voltage pulses needed to create a spark at the spark plugs.
Usage
The term "ignition coil" refers specifically to this electrical transformer. It is a countable noun.
Examples: * A faulty ignition coil can cause engine misfires. * The mechanic replaced the ignition coil to fix the starting problem. * Modern engines often have one ignition coil per cylinder.
Advanced Usage
- "Coil-on-plug" (COP): A modern ignition system design where each spark plug has its own dedicated mounted directly on top of it.
- In technical diagnostics, one might refer to testing the
