Title:
CONTROLLER FOR COMPOSITION OF MIXTURE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS5943941
Kind Code:
A
Abstract:
A regulating device is proposed for the mixture composition of an internal combustion engine having a signal sensor and having regulating ranges which can be switched over between lambda equals one and the lean range. The lambda-equal-to-one regulation is effected by means of a two-point regulator and the lean regulation is effected either via an altered set-point value of the two-point regulator or with the aid of a steady regulator. The transitions between the two types of regulation take a course dependent on a selectable function, in order to avoid abrupt changes in rpm. A switchover is also made to controlled operation for a brief period at the beginning of each type of regulation.
