1. A control apparatus for an internal combustion engine comprising:
- a controller that;
executes a stop control for stopping the internal combustion engine when a predetermined engine stop condition is established, the stop control comprising an operation to stop a supply of fuel to the engine; and
executes a re-start control for re-staffing the internal combustion engine when a predetermined engine re-start condition is established, the re-start control comprising an operation to resume the supply of fuel to the engine, wherein the controller discontinues the stop control for stopping the engine when the predetermined engine re-start condition is established during a predetermined period between establishment of the predetermined engine stop condition and stoppage of the internal combustion engine and the predetermined period is a period taken for an engine stop preparatory control that adjusts an engine operation and that is executed before the operation to stop the supply of fuel to the internal combustion engine as to decrease a speed of the internal combustion engine.

Abstract
A control apparatus and method of an internal combustion engine performs a predetermined stop control of the engine that includes a control to stop the supply of fuel to the engine upon establishment of a predetermined stop condition, and a re-start control that includes a control to restart the supply of fuel to the engine in response to the establishment of a predetermined re-start condition. The apparatus has a stop control discontinuing device for discontinuing the stop control if the re-start condition is established within a predetermined period between establishment of the stop condition and a stop of the engine.
