ジンにおける空燃比制御装置。 In a turbocharged gas engine, a rotation detector detects the engine rotation, a differential pressure detector detects the air flow rate in the air flow path in the intake passage, and a pressure sensor detects a predetermined gas component in the exhaust gas. An air-fuel ratio detector that detects fluctuations in fuel ratio, an intake controller that adjusts the boost pressure, a gas control valve that adjusts the fuel gas flow rate, the rotation detector, the differential pressure detector, and the air-fuel ratio detector. Air-fuel ratio control in a gas engine, characterized in that it is equipped with a control means for controlling the intake controller and the gas control valve by outputting a control signal that maintains the excess air ratio constant by receiving the output signal as an input. Device.
