Abstract
PURPOSE: To accurately sense the warm-up state of an engine and improve the correction of its air-fuel ratio at the time of warming up the engine, by supplying secondary air to an intake passage with a control valve and forming the control valve to a response type for cooling water temperature.
CONSTITUTION: A secondary air supply port 8 and fuel injection valve 5 are opened to the inside of an air intake passage 1 at the downstream of a throttle valve 2. The other end of the supply port 8 is opened to an air cleaner 19 through a secondary air supply passage 9 provided with a secondary air control valve 10. Then the control valve 10 comprises a wax sealed body 15 inserted into cooling water 14, and its expansion moves a plunger 16 to communicate the passage 9.
