Title: Control device of internal combustion engine
Inventor: SATA KOTA
IPC: F02P5/145
Filed: 2007-06-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of surely suppressing the stepping of torque and the point of inflection on the ascending curve of engine rotational speed from occurring when a rotational speed feedback control by ignition timing is started after the engine is started.  <P>SOLUTION: A guard value is set for the proportional of the rotational speed feedback control by the ignition timing, and the proportional is limited within the guard value. Since a feedback correction amount is suddenly introduced during the start of the rotational speed feedback control, it can be avoided that the ignition timing is discontinuously changed. Consequently, since the stepping of torque is suppressed, the point of inflection produced on the ascending curve of the engine rotational speed can be suppressed.  <P>COPYRIGHT: (C)2009,JPO&INPIT
