The device that steps up the voltage to the level necessary to create a spark in each cylinder is called the ignition coil. Here's how it works:
1. The ignition coil is a type of autotransformer that takes low voltage from the battery (typically 12 volts) and steps it up to a much higher voltage (thousands of volts).
2. This high voltage is then sent to the spark plugs in each cylinder of the engine.
3. When the voltage reaches the spark plug, it creates a spark across the spark plug gap, igniting the air-fuel mixture in the cylinder to start the combustion process.
In summary, the ignition coil plays a crucial role in the ignition system of a vehicle by stepping up the voltage to create the spark needed for combustion in each cylinder.
