The ignition system, by sending a spark in a timely and purposeful manner, ensures the correct combustion of the fuel-air mixture in the engine. And it happens instantly, because. at 3000 rpm each engine cylinder requires 25 sparks per second. With 100 sparks per second in a four-cylinder engine, that's 6,000 sparks per minute, 360,000 per hour, and so on.
In order for a spark from a spark plug to enter the combustion chamber at all, there must be a voltage of 30,000 V between the electrodes of the spark plug. But only 12 V is supplied from the battery. This means that the battery voltage must be significantly converted. Further, when transmitting a spark, we are not talking about tenths or hundredths of a second, but about thousandths. A little faster or a little slower and there are defects in the ignition and in the engine power.
