What provides ignition

In order that the spark from a spark plug in general could get to the combustion chamber, between electrodes of a candle there has to be tension in 30 000 V. No from the accumulator tension comes only to 12 V. Znachit, tension of the accumulator has to be significantly transformed. Further, by transfer of a spark, it is not about the tenth or 100-th fractions of a second, and about thousand. Slightly quicker or slightly more slowly defects in ignition and in engine capacity also appear.
