Abstract

PURPOSE: To make the best use of the characteristic of a flat map by a method wherein the concentration of a gas mixture in a power region is made accurately irrespective of the temperature of an engine so that sufficient power is driven.
CONSTITUTION: Data D are given to slow and main solenoids 3 and 4 in such a manner that Data DSM from the flat map are increased in proportion to the temperature Tw of the engine and also to an air sucking negative pressure Vc. Consequently, it becomes possible to concentrate the gas mixture to a sufficient degree whenever a great power is required to be deriven from the engine despite the flat map is used so that the required A/F control is performed in a simple manner and with surety for all the operation condition from an idle condition to a power region in which the maximum output is derived.
