1. An internal combustion engine, comprising:
a cylindrical cylinder having a cylinder central axis;
an intake passage connected to the cylinder;
a water injection valve located in the intake passage and configured to inject water into the cylinder, the water injection valve having a water valve tip and a water axis, the water valve tip being a tip of the water injection valve, and the water axis being an injection axis of the water from the water injection valve; and
a fuel injection valve configured to inject gaseous fuel directly into the cylinder, the fuel injection valve having a fuel valve tip and a fuel axis, the fuel valve tip being a tip of the fuel injection valve, and the fuel axis being a main injection axis of the gaseous fuel from the fuel injection valve, wherein
the internal combustion engine has a specific cross-section that is a plane parallel to the cylinder central axis, the specific cross-section including the water valve tip and the fuel valve tip, and
the water axis and the fuel axis intersect each other in the cylinder in the specific cross-section, wherein the fuel axis is located farther from the water injection valve than a central axis of the fuel injection valve in the specific cross-section.
