FIELD: engines and pumps.
SUBSTANCE: device for measurement, control and diagnostics of the combustion process in the combustion engine chamber contains an ionic detector including electrodes isolated from each other. One electrode, negative, is cylinder head casing. Another one, positive, is a metal rod isolated from the cylinder head. The second electrode is installed in the hole which is in the cylinder head. The metal rod of the second electrode is covered with a layer of electroinsulating vanish and has a spherical build-up at one end. The hole in the cylinder head casing is equipped with a bevel face and has a diameter which is equal to the rod diameter. The device contains a registering device for sensor readings.
EFFECT: increased reliability and prolonged life of the measurement system for ionic currents in the combustion chamber.
