Starting from the moment of the invention of electric ignition by the German brilliant engineer Robert Bosch, the search for new and new ways to increase the efficiency of engines is not stopped. In particular, engineering geniuses continue to look for optimal material for electrodes, change the number of electrodes in candles (to increase the stability of the detonation of the fuel mixture) and even try and experience candles of various sizes, hoping to achieve the most productivity of the engine with the optimal ratio of cost and operational resource of light lights.
