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.

Claim (Index 6):
The gas engine drive system according to  claim 1 , further comprising a torque meter that detects an output torque of the gas engine, wherein\n the controller calculates the calorific value of the fuel gas based on the output torque of the gas engine, which is detected by the torque meter, and a fuel injection amount from the fuel injection valve, and changes the target value from the first setting value to the second setting value when the calculated calorific value is equal to or less than the threshold.
