ABSTRACT:
A fuel injector for an internal combustion engine is provided. The fuel injector is to be installed in a cylinder head of the engine and has a fuel pressure sensor working to measure the pressure of fuel within a injector body. The fuel pressure sensor is installed in a portion of the injector body which is to be located away from the cylinder head of the engine across a portion of the injector body on which a mechanical pressure is exerted by an external member such as a fuel supply pipe or a fuel drain pipe, thereby keeping the fuel pressure sensor free from internal stress, as arising from the mechanical pressure exerted on the injector body, to ensure the accuracy in measuring the pressure of the fuel.
