Japanese Patent JPH05215012
Kind Code:
A
Abstract:
PURPOSE: To improve drivability when a throttle valve is fully opened in an accelerating time.
CONSTITUTION: A flow rate control valve 8 which opens and closes of an air bleeding passage 7 of an evaporator 1 is controlled for adjusting an air-fuel ratio of air-fuel mixture to be supplied to an engine. At this time, an opening/ closing condition of a throttle valve 4 is detected, while an engine speed is detected.
