Abstract
A gas engine drive system includes: a gas engine including combustion chamber; a turbocharger including a compressor and turbine; a fuel injection system that injects fuel gas into intake air that is supplied from compressor to combustion chamber via an intake passage; a pressure detector detecting a charge air pressure; a temperature detector detecting the intake air's temperature; and controller controlling the fuel injection system. The controller: when required output decreases, determines the charge air pressure's lean limit based on target injection amount corresponding to required output that has decreased; if the charge air pressure is lower than or equal to the lean limit, decreases fuel injection amount to target injection amount; if the charge air pressure is higher than lean limit, brings fuel injection amount to zero. When the charge air pressure becomes lower than or equal to the lean limit, increases fuel injection amount to target injection amount.
