Abstract
PURPOSE: To improve responding capacity and accuracy in air-fuel ratio by providing an idling speed control valve of rotary-shutter type which is driven by a pulse motor to an internal combustion engine with an electronic controlled fuel injection device.
CONSTITUTION: An air cleaner 3, and air flow meter 4, and a throttle valve 5 are provided to an inlet tube 2 of an engine 1 to control fuel from an injection valve, which is not indicated in the figure, in accordance with motions of the meter 4. Also, a by-pass air passage 6 which connects upstream and downstream sides of the throttle valve 5 is provided, and a disk-shaped rotary shutter 24 as a flow rate control valve with a partial opening 26 is provided over said passage 6. The shutter 24 is interlocked with a pulse motor 21 and turned in a rotating angle which is in proportion to the number of pulses to control air-fuel ratio at idling.
