CONTROLLER OF INTERNAL COMBUSTION ENGINE

Title:

CONTROLLER OF INTERNAL COMBUSTION ENGINE

Document Type and Number:

Japanese Patent JP2005194902

Kind Code:

A

Abstract:

To prevent the rotational speed of an internal combustion engine from being excessively raced without being affected by the change of rotating behavior after the start of the internal combustion engine in the controller of the internal combustion engine.

Until the rotating peak of the rotating speed of the internal combustion engine is detected after the start of the internal combustion engine, control parameters (for example, igniting timing) different from intake flow rate related to the output of the internal combustion engine are set when the output of the internal combustion engine is lowered less than parameter values in idle (for the ignition timing, spark timing is delayed). After the rotating peak is detected, the control parameters are adjusted to parameter values in idle.
