FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention can be used for diagnosing condition and control of internal combustion engines. Proposed method is implemented by measuring time of flow of discharge or charge current through periodically chargeable capacitor whose plates are connected with electrodes placed in gas medium. Proposed invention provides possibility of measuring ionic conduction of gas medium between spark plug electrodes using simple method providing high accuracy of measurements.
EFFECT: reduced expenses for taking measurements.
