Abstract
A fuel injector for an internal combustion engine is provided which has a fuel supply path and a nozzle chamber. The fuel supply path extends a spray hole. The nozzle chamber is defined in the fuel supply path. A nozzle is disposed within the nozzle chamber to establish or block a fluid communication between the fuel supply path and the spray hole. A fuel pressure sensor is installed in the fuel injector so as to be exposed to the fuel in the nozzle chamber. Specifically, the fuel pressure sensor is located closer to the spray hole than a prior art structure in which the fuel pressure sensor is installed in a fuel supply pipe, thus resulting in increased accuracy in measuring a change in pressure of the fuel arising from the spraying of the fuel from the spray hole.
