The fuel injection device and a compression ignition internal combustion engine

Fuel control means includes a compression ignition type internal combustion engine for controlling the nozzle so as to pre-stage injection and latter stage injection control device as a fuel injection cycle. Timing the interval timing and preceding-stage injection control means controls ejection so that the preceding peak interval (Atl) timing of the peak timing and the rear section substantially satisfy the condition. With the proviso that the spacer (Atl) is 0.5 times the reciprocal of the maximum frequency of the combustion noise level.
