  "textContent": "The object of the present invention is to enable the reliable compression ignition from starting of a pilot oil ignition gas engine in whose cylinder head there is provided a precombustion chamber unit with pilot injection valve that has liquid fuel injection valves and a precombustion chamber by using the injection of pilot oil from the liquid fuel injection valves, and to thereby allow the engine to be started smoothly. The position of a fuel rack (fuel control rod) that controls the discharge quantity of fuel injection pumps that feed pilot oil to the liquid fuel injection valves is controlled by a control apparatus via a rack control actuator (a position control actuator). In addition, the control apparatus counts the engine speed from pulses generated by a speed sensor and, in a region where the engine speed is low, sets the discharge quantity of the fuel injection pumps to a large quantity. As a result, pilot oil is reliably injected from the liquid fuel injection valves, and gaseous fuel is reliably ignited and burned.",
