A system for detecting abnormalities in a gas engine comprises: a pressure measuring device for measuring the pressure within each engine cylinder to generate corresponding signals; a device for determining from these signals the maximum pressure for every cycle of the engine operation; a comparator circuit for comparing each maximum pressure with reference values of a specific range and, when the maximum pressure is outside of that range, generating a corresponding signal indicating the existence of an abnormality; and an actuator operating in response to this signal to actuate and close a shut-off valve in the fuel gas supply line of the engine, an alarm device being simultaneously activated by this signal.

A system for detecting abnormalities in a gas engine with at least one cylinder and a fuel gas shut-off valve and means for closing the shut-off valve upon detection of an abnormality, said system comprising: pressure detecting means for detecting the pressure within each cylinder to generate corres

A system for detecting abnormalities in a gas engine with at least one cylinder and a fuel gas shut-off valve and means for closing the shut-off valve upon detection of an abnormality, said system comprising: pressure detecting means for detecting the pressure within each cylinder to generate corresponding detection values; maximum pressure detecting means for determining from said detection values the maximum pressure within the cylinder for every cycle of the engine operation; comparator means for comparing each maximum pressure thus determined with reference values of a specific range and, when said maximum pressure is outside of said range, generating a corresponding signal; and actuating means operating in response to said signal to actuate the shut-off valve.
