System of ignition

System of ignition, sending in due time and purposefully a spark, provides the correct process of combustion of fuel-air mix in the engine. And it occurs instantly since at 3000 turns each cylinder of the engine requires 25 sparks a second. At 100 sparks a second in the four-cylinder engine, it makes 6000 sparks a minute, 360 000 in an hour, etc.
