Experimental studies of the ignition system of the engine idling. With the help of current and voltage sensors made visualization, transformation and analysis of information about the characteristics of energy spark discharge in the cylinder of the engine idling. Produced by processing waveform is shown that with increasing rotation speed of motor there is a reduction of the energy released in the electrode gap of the spark plug. Reducing the energy released (at a constant value of the energy stored in the magnetic field of the ignition coil) due to its redistribution between the capacitive and inductive discharge phases. By increasing rotation speed of motor the breakdown voltage increases, so does the excess air ratio, which also increases the breakdown voltage electrode gap spark plugs.
