Abstract: A method for monitoring an engine cylinder in an internal combustion engine includes, for each engine cycle, detection of the ionisation current generated in the cylinder in a predetermined time interval of a combustion cycle, generation of a signal representing the ionisation current and comparing a maximum value of the signal with a threshold value. Successively, the value of one or more parameters associated with the signal can be changed with respect to an equal number of corresponding reference values when the maximum value of the signal exceeds the threshold value, to reduce the maximum value of the signal in the time interval of a successive combustion cycle. The presence of water in the cylinder can be determined when the maximum value of the signal exceeds the threshold value for a predetermined first number of combustion cycles occurring within a predetermined period of time.

Abstract: A method for ignition control in a combustion chamber of an internal combustion engine by means of acquiring an electric signal relating to ionizing currents emitted in said combustion chamber, comprising a step of detecting a substantially stepped trend of said electric signal and a consequent step of inhibiting a corrective action of an ignition advance and/or of a fuel injection limitation curve in the combustion chamber.

Abstract: Measuring sensor, in particular of a level of a liquid, in particular for the lubricating oil of an internal combustion engine, the sensor comprising a body with a longitudinal extension with at least one related intermediate portion having cylindrical symmetry with respect to said longitudinal extension and a bushing internally complementary to said intermediate portion, so that said body can freely rotate in the bushing with respect to said longitudinal extension and wherein the bushing externally comprises fixing means for fixing the sensor to an opening of a container of said liquid.
