The job considers the questions of determining of signal spectral distribution in secondary spark formation time. Was fulfill the investigation discharge current variation dynamics depending on air-fuel mixture state at the piston engine cylinder. Specified the power of signal, proceeding at capacitive phase moment of electrical discharge on spark for engine different conditions.</p>
