Abstract
Provided is a control method that suppresses a surge in rotation speed due to excess fuel when a load of a gas engine has abruptly dropped. This control device is for controlling a vent valve that is connected to the downstream side of a fuel control valve of a fuel supply line through which fuel is supplied to a gas engine and that is provided in an exhaust line for guiding the fuel to the outside of the fuel supply line, the control device comprising: a signal acquisition unit which acquires a signal indicating an abrupt drop in a load of the gas engine; and a control unit which opens the vent valve upon acquisition of said signal.
Claims12
A control device for a vent valve provided in an exhaust line that is connected to a downstream side of a fuel control valve in a fuel supply line that supplies a fuel to a gas engine, and guides the fuel to an outside of the fuel supply line, the control device comprising:
- a signal acquisition unit that acquires a signal indicating a rapid decrease in a load of the gas engine;
- and
- a control unit that opens the vent valve when the signal is acquired.
A control method for a vent valve provided in an exhaust line that is connected to a downstream side of a fuel control valve in a fuel supply line that supplies a fuel to a gas engine, and guides the fuel to an outside of the fuel supply line, the control method comprising:
- a step of acquiring a signal indicating a rapid decrease in a load of the gas engine;
- and
- a step of opening the vent valve when the signal is acquired.
A program causing a computer to execute:
- a step of acquiring a signal indicating a rapid decrease in a load of a gas engine;
- and
- a step of opening a vent valve provided in an exhaust line that is connected to a downstream side of a fuel control valve in a fuel supply line that supplies a fuel to a gas engine, and guides the fuel to an outside of the fuel supply line, when the signal is acquired.
