An internal combustion engine relies on several dedicated components in the ignition system to create and deliver spark. Match each ignition component to its primary operational role.
- Ignition CoilSteps up low battery voltage into high-voltage electrical energy
- Spark PlugDischarges high-voltage current across an electrode gap to ignite compressed air and fuel
- Ignition Control ModuleActs as an electronic switch to open and close the coil's primary ground circuit
- Crankshaft Position SensorMonitors engine rotational speed and cylinder position to signal spark timing
Answer
Ignition Coil matches with stepping up low battery voltage to high voltage; Spark Plug matches with discharging current across an electrode gap; Ignition Control Module matches with switching primary circuit ground; Crankshaft Position Sensor matches with monitoring rotational position for timing.
Each item accurately pairs the functional component of an automotive ignition circuit with its direct role: the coil steps up voltage, the spark plug produces the ignition arc, the module switches the primary ground to trigger induction, and the crankshaft sensor measures engine rotation for precise ignition timing.
