ABSTRACT:
A reliability ensuring system for an internal combustion engine comprises an operating state detecting means for detecting the value of an engine parameter to be controlled which could affect the reliability of the engine and should be controlled when it goes outside a normal region. A preset value generating means generates a plurality of preset values with respect to the value of the engine parameter to be controlled, the preset values corresponding to different degrees of deviation of the engine parameter to be controlled from the normal region. An output signal generating means generates an output when the detected value of the engine parameter to be controlled exceeds one of the preset values for a predetermined time interval. The predetermined time interval is determined for each preset value so that it increases as the degree of deviation of the factor to be controlled from the normal region is reduced. A control means controls an engine parameter affecting the engine parameter to be controlled to move the value of the same toward the normal region when the output signal is generated.
