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...
1. A control apparatus for an internal combustion engine comprising: a high pressure fuel pump for supplying a high pressure fuel to the internal combustion engine;a low pressure fuel pump for supplying the fuel to the high pressure fuel pump;at least one fuel injector for injecting the fuel directly into a cylinder of the engine;a fuel injection controller for driving the high pressure fuel pump and the injector;a high pressure fuel pipe connected between the high pressure fuel pump and the injector,fuel pressure detecting means provided to the high pre...
