Abstract

PURPOSE: To enlarge the correction width of the air fuel ratio by controlling the opening and closing of a jet air control valve and a solenoid valve using signals from temperature sensors, and exhaust gas detector and a manifold negative pressure detector by a computer.
CONSTITUTION: A passage 9 for an air fuel ratio correcting gaseous mixture is connected to a jet air passage 5. A jet air control valve 7 which opens and closes its inlet side is provided at either one of both passages and a solenoid valve 14 is provided at another passage. The jet air control valve 7 or the solenoid valve 14 is opened and closed at the time of low temperature driving, normal temperature driving or high temperature driving, using signals from temperature sensers 19 and 20, an exhaust gas detector 21, a manifold negative pressure detector 18, by a computer 15 thereby to control so that the air fuel ratio adapted to the starting and heating is formed. Accordingly, the correction width of the air fuel rario in each driving range can be largely expanded.
