Abstract
A fuel injector which may be employed in injecting fuel into an internal combustion engine. The fuel injector includes an injector body and a head body formed to be separate from the injector body. The head body has installed therein a fuel pressure sensor working to measure the pressure of fuel in the fuel injector and is joined detachably to the injector body. The fuel injector alternatively includes an injector body and a fuel pressure-sensing unit equipped with a fuel pressure sensor. The fuel pressure-sensing unit is installed detachably on the injector body. This structure provides enhanced productivity of the fuel injector and facilitate the ease of replacement of the fuel pressure sensor.
