How does the ignition coil works on volvo s70?

Answer 1

The ignition coil in a Volvo S70 transforms the vehicle's battery voltage (typically 12 volts) into a much higher voltage, often around 20,000 to 45,000 volts, necessary to create a spark in the engine's combustion chamber. It operates by using an electromagnetic field generated when electricity passes through a primary winding, which then induces a much higher voltage in the secondary winding. When the ignition control module signals the coil, it releases this high voltage to the spark plugs, igniting the air-fuel mixture in the engine. This process is crucial for the engine's performance and efficiency.
