Sytytyspuoli

Sytytyspuoli refers to the ignition system side of an internal combustion engine, specifically the components responsible for generating the spark that ignites the air-fuel mixture. In older vehicles, this system typically included a distributor, ignition coil, spark plugs, and contact breaker points. The distributor mechanically directed the high-voltage current from the coil to the correct spark plug at the precise moment of combustion. The ignition coil acted as a step-up transformer, converting the vehicle's low battery voltage into the high voltage required to create a spark across the spark plug gap.

Modern vehicles have largely transitioned to electronic ignition systems, which eliminate mechanical components like distributors and contact breaker points. These systems utilize sensors to monitor engine speed and position, and a control unit (ECU) to precisely time the spark. The ignition coil is often integrated into a coil-on-plug design, where each spark plug has its own dedicated ignition coil. This simplifies the system, improves reliability, and allows for more precise ignition timing, leading to better fuel efficiency and reduced emissions. The sytytyspuoli is therefore a critical subsystem for the operation of any spark-ignition gasoline engine.
