Abstract
The diesel internal combustion engine fuel injection system includes an accumulator nozzle having its opening pressure close to its closing pressure so as to provide a high turn down ratio without excessive maximum charging pressure. The accumulator nozzle may include a displacement piston which is used to lower the charging pressure by a fixed amount after the injection of fuel into the engine cylinder commences. Alternatively, the accumulator nozzle may include a small moveable piston which serves to raise the closing pressure after the injection of fuel into the engine cylinder commences.
