APPARATUS FOR AND METHOD OF CONTROLLING FUEL INJECTION OF INTERNAL COMBUSTION ENGINE

摘要

There is provided a configuration in which a cylinder which is in an inlet stroke when an internal combustion engine is in a stop (automatic stop) state is determined and stored, and when starting the engine upon detection of a start request, the fuel injection of an initial cycle to the cylinder, which has been determined as having been stopped in the inlet stroke when the engine was in the stop state before starting, is split into a plurality if injections at least including an injection before engine rotation, to thereby perform injections. As a result, startability is improved while suppressing pre-ignition at the time of starting.

1. An apparatus for controlling fuel injection of an internal combustion engine for a vehicle comprising:
a fuel injection valve arranged so as to inject fuel to an inlet port of each cylinder of the internal combustion engine; and a control unit which controls driving of the fuel injection valve comprising: an inlet stroke stopped cylinder determination section which determines a cylinder stopped in an inlet stroke when the internal combustion engine is stopped; a start request detection section which detects a start request of the internal combustion engine; and a start-commencement cylinder injection control section which, when starting the engine upon detection of the start request, splits fuel injection of the initial cycle to the cylinder, which has been determined as being stopped in the inlet stroke when the internal combustion engine was stopped before starting, into a plurality of injections to thereby perform injections, so that the fuel is injected respectively before and after engine rotation.
