摘要： A Karman vortex generator is disposed in the air intake passage of an internal combustion engine. The frequency of the Karman vortex generated by the generator is detected by a Karman vortex frequency detector to measure the flow rate of intake air. The frequency of the Karman vortex is in proportion to the flow rate of intake air with a Strouhal number being the constant of proportionality thereof. However, when the flow rate or the flow velocity of intake air is within a certain range, the Strouhal number fluctuates and the proportionality between the Strouhal number and the flow rate of intake air is broken. This range is shifted when the kinematic viscosity of intake air changes. The kinematic viscosity of intake air depends upon the temperature thereof. Thus, the temperature of intake air is detected, and the output of the Karman vortex frequency detector is corrected when the air flow velocity represented by the output of the Karman vortex frequency detector is in such a range as to vary the Strouhal number taking into account the shift of such range due to the change of the kinematic viscosity of intake air.

摘要： 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.
