    摘要: In a control apparatus for an internal combustion engine, when a fuel pressure detected by the fuel pressure detecting unit is not smaller than a threshold P_a, the value opening time duration of a injector is increased to a value larger than its normal value, such control as to stop fuel injection from the injector is inhibited, the low pressure fuel pump is stopped, thus quickly lowering the fuel pressure. After the fuel pressure is lowered, the valve opening time duration of the injector is returned to the normal value, and a discharge quantity of the low pressure fuel pump is changed on the basis of a difference between the fuel pressure detected by the fuel pressure detecting unit and a target fuel pressure.
