【発明の名称】内燃機関のアイドリング回転数の調整装置
Document Type and Number:
Japanese Patent JPH0756231
Kind Code:
B2
Abstract:
In a system for regulation of the idling speed of an internal combustion engine acting through an electrical positioning means for the minimum-opening position of the throttle valve, the building-up of troublesome fluctuations in engine speed as the result of the characteristics of the regulation loop is counteracted in response to detection of the rise of such fluctuations or of their imminence as the result of an excessively rich mixture (on the basis of the signal from a probe in the exhaust pipe). When such a condition is detected, the amplification factors in the controller stage of the regulation loop are reduced, the reference desired idling speed value is raised and the lower limit of the regulation range is also raised. These parameters are returned to normal when the throttle valve moves away from its idling speed position.
