Abstract

A fuel injection device (fuel supply system) of a common rail type fuel injection system for an engine includes a pressure sensor disposed in a fuel inlet of an injector for measuring a fuel pressure at a position where the sensor is disposed and an ECU for sensing various kinds of pressure fluctuations associated with the injection including a pressure leak due to an injection operation of the injector and waving characteristics due to actual injection thereof based on sensor outputs from the pressure sensor. The ECU serially obtains the sensor outputs from the pressure sensor at intervals of 20 μsec.
