Document Type and Number:
Japanese Patent JP3424882
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To prevent lowering of engine performance by setting a command value of fuel injection pressure in consideration of operational delay and electric delay.
SOLUTION: A fuel injection pressure setting means 102 sets basic fuel injection pressure PB from fuel injection quantity Q and engine speed Ne and sets corrected fuel injection pressure PA by adding a pressure value ΔP set in accordance with output of a transient driving state judging means 104 to the basic fuel injection pressure PB at the time when the transient driving state judging means 104 judges that an engine is in a transient state from a change of accelerator opening θ. A fuel injection pressure control means 106 controls a fuel pump 109 in accordance with the basic fuel injection pressure PB or the corrected fuel injection pressure PA, and a fuel injection timing control means 107 controls an accumulator unit injector 108 in accordance with fuel injection timing T.
