  "textContent": "Even when only the fuel oil is injected into a cylinder liner, a decrease in the performance of an internal combustion engine due to a decrease in fuel-injection pressure and a deterioration in combustibility is prevented, and an increase in dust and black smoke is also prevented. A fuel injection device (1) for an internal combustion engine provided with, for one cylinder, at least two fuel-injection valves (10) provided with valve-opening-pressure adjusting devices (30) that adjust the valve-opening pressure of needle valves (15), wherein, when injecting fuel oil and an inert substance into a cylinder liner, the fuel oil and the inert substance are injected from all of the fuel-injection valves (10); and, when injecting only the fuel oil into the cylinder liner, the valve-opening-pressure adjusting device (30) is operated so that the needle valve (15) of at least one of the at least two fuel-injection valves (10) is pressed by a force that is equal to or greater than the valve-opening pressure of the needle valve (15), blocking the fuel injection from that fuel-injection valve (10).",
