ABSTRACT:
A cylinder injection type fuel control apparatus secures the operation of an internal-combustion engine even if a fuel supply system of the internal-combustion engine fails. The cylinder injection type fuel control apparatus is equipped with an injector (3) which is driven by an output signal based on a computation result of an electronic control unit (2) and which supplies fuel to the respective cylinders of the internal-combustion engine. A failure of a high-pressure fuel system is detected according to the integrated number of engine stalls that take place immediately after startup, or other means, and if a failure of the high-pressure fuel system has been detected, then the control is switched to a low-pressure fuel supply system to run the internal-combustion engine.
