(54)Fuel pressure sensor/sensor mount assembly, fuel injection apparatus, and pressure sensing apparatus


(57) A fuel pressure sensor/sensor mount assembly (70z) in which a fuel pressure sensor (60z) is so mounted as to exposed to a high-pressure fuel path through which fuel is supplied to a fuel injector, a fuel injection apparatus equipped with a built-in fuel pressure sensor, and a pressure sensing apparatus working to measure the pressure of fuel in a fuel injector are provided. The fuel pressure sensor/ sensor mount assembly is disposed between the high-pressure fuel path and the fuel injector, thus permitting the size of the fuel injector to be minimized without sacrificing the accuracy in measuring the pressure of the fuel. The fuel injection apparatus and the a pressure sensing apparatus are designed to ensure desired accuracy in measuring the pressure of the fuel.
