ABSTRACT:
An apparatus detects trouble states in a gas engine in which the exhaust gas pressure after combustion in each cylinder is measured by a pressure sensor installed on a collecting exhaust pipe. An average value of the exhaust pressure, a standard deviation and a fluctuation values of the average value in each cylinder is calculated. Based on the calculated data, it is specified whether the trouble occurring in the gas engine corresponds to a misfire, a leakage in the inlet value or a leakage in the outlet valve, as well as which cylinder is the cause of the problem.
