ABSTRACT:
An accumulator fuel injection apparatus is provided in which average pressure in the common rail can be detected by an extremely simple and inexpensive means with increased accuracy to be used as a control signal for controlling fuel injection. A pressure detection room is formed at an end part of the accumulation chamber such that the pressure detection room is connected to the accumulation chamber of the common rail, an orifice is provided between the pressure detection room and the accumulation chamber of the common rail to communicate the pressure detection room with the accumulation chamber by a throttled sectional area, and a common rail pressure sensor for detecting fuel pressure in the accumulation chamber is attached to an end of the common rail to face the pressure detection room.
