Abstract
A fuel injection valve equipped with an in-cylinder pressure sensor is provided in which a fuel injection valve is fitted into an injection valve mounting hole provided in an engine, the fuel injection valve injecting fuel from a front end of a valve housing part into a combustion chamber of the engine, and the in-cylinder pressure sensor, which is cylindrical and has a front end facing the combustion chamber, and a cylindrical signal circuit tube fitted and connected to an inner peripheral face of a rear end of the in-cylinder pressure sensor are fitted and fixed to an outer peripheral face of the valve housing part, housed in the injection valve mounting hole, of the fuel injection valve. In such fuel injection valve, the signal transmission device connected to an in-cylinder pressure sensor does not vibrate within an injection valve mounting hole, thus enabling its durability to be ensured.
