The ignition system, by sending a spark in a timely and purposeful manner, ensures the correct combustion of the air-fuel mixture in the engine. And it happens instantly, because. at 3000 rpm, each cylinder of the engine requires 25 sparks per second, which in our four-cylinder engine is 100 sparks per second, 6000 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 at least 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 later or a little earlier, defects in the ignition appear and, consequently, a decrease in engine power.
