Abstract: <P>PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of reducing the quantity of air (quantity of oxygen) exhausted from the engine in a period up to stopping rotation of the engine from when generating a request for stop operation of the engine (an engine stopping request).  <P>SOLUTION: This control device continues combustion while setting the ignition timing to the excessively advancing ignition timing advanced by an excessively advancing quantity θadv more than the optimal ignition timing θmbt, when the engine stopping request is generated (XAD=1), and an engine speed is reduced thereby (Step 320). When an engine speed NE becomes a threshold value engine speed NEth or less, supply of fuel is cut off, and execution of ignition is stopped (Step 335). Since the fuel supply is stopped after the engine speed reduces while burning an air-fuel mixture and the engine speed becomes the threshold value engine speed or less, a rotation quantity by inertia of the engine up to stopping the rotation of the engine is small. Thus, a large quantity of air is not exhausted from the engine.  <P>COPYRIGHT: (C)2009,JPO&INPIT
