Abstract
A gas engine drive system includes: a gas engine; a turbocharger including a compressor and a turbine connected to the gas engine; a fuel injection valve provided on the gas engine; a fuel supply line leading a fuel gas to the fuel injection valve, the fuel supply line having a pressure regulating valve; a first pressure meter detecting an intake air pressure; a second pressure meter detecting a fuel supply pressure being a pressure at a pressure regulating valve downstream side; and a controller controlling the pressure regulating valve such that a pressure difference between the fuel supply pressure and the intake air pressure is a target value. The controller changes the target value from a first to a second setting value higher than the first when a load on the gas engine increases rapidly or when a calorific value of the fuel gas is less than a threshold.
