Abstract: <P>PROBLEM TO BE SOLVED: To solve such a problem wherein there is a technology of correcting the amount of main injection with a pressure pulsation as a fit map because the amount of main injection is varied due to pressure pulsation by a pilot injection, but in the technology, the fit map must be produced based on a large amount of test data by actual equipment.  <P>SOLUTION: It is found that a fluctuation period of the pressure pulsation corresponds to a closed opening end pressure pulsation generated at fuel pipe passages 11 and 12 communicating with a nozzle chamber 8 of an injector 2, and a period of the pressure pulsation is calculated from lengths L1 and L2 of the respective fuel pipe passages 11 and 12. Further, based on a fuel temperature Tf, a common rail pressure Pc, phase differences θ1 and θ2 of the pressure pulsation, and the amount of pilot injection, a pressure fluctuation ΔP(t) is calculated. The pressure fluctuation ΔP(t) is corrected with a degree of incidence Qef according to a fuel pressure thereby calculating a main injection correction ΔQ(T). Accordingly, since the period of the pressure pulsation is found by calculation, it is not necessary to collect the large amounts of test data by the actual equipment.  <P>COPYRIGHT: (C)2004,JPO
