Abstract
PURPOSE: To protect the exhaust cleaning system of an internal combustion engine by suppressing the fuel injection from a fuel nozzle by reducing the pressure of a carburetor float chamber when an ignition circuit does not function.
CONSTITUTION: A multiple carburetor 3 has a connecting pipe 14 connected to the upper space of a float chamber, said connecting pipe 14 being open to atmosphere via an air passage 15 which has a solenoid change-over valve 16. A negative pressure passage 17 is connected to said change-over valve 16 and also to the downstream of a throttle valve 11 via the 1st bracking passage 17a having an orifice 19 and to the upstream of the throttle valve 11 via the 2nd bracking passage 17b having a check valve 20. The change-over valve 16 opens up the air passage 15 when an ignition circuit 24 functions and connects both the brancking passages when the circuit 24 does not function.
