Abstract:
To impede fluctuation of air/fuel ratio by air jetted from a port taking out a negative pressure to a brake booster.
In an intake passage in the upstream of a throttle valve 9 and a mass flow meter 6, a throttle part 10 is provided, in the throttle part 10, a negative pressure taking out port 11 is provided. A negative pressure generated in the throttle part 10 is guided in a brake booster 20 through a check valve 13.
