具有燃料压力传感器的燃料喷射器
摘要：
一种燃料喷射器，它可以用来把燃料喷射到内燃机中。燃料喷射器包括喷射器主体和形成为与喷射器主体相分开的头部主体。该头部主体在其中安装了燃料压力传感器，该传感器进行工作以测量燃料喷射器中的燃料压力并且可拆下地结合到喷射器主体上。燃料喷射器还包括喷射器主体和燃料压力探测装置，该燃料压力探测装置设置有燃料压力传感器。燃料压力探测装置可拆下地安装在喷射器主体上。该结构使得燃料喷射器的生产率得到提高并且有利于方便地更换燃料压力传感器。
摘要（英）：

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.
