Claims

[Scope of utility model registration request]

The downstream end of the throttle valve of the carburetor body is equipped with an exhaust gas concentration detection sensor that detects gas components in the exhaust gas, and an air-fuel ratio control device that feedback controls the air-fuel ratio according to the output of the exhaust gas concentration detection sensor. an annular groove is formed in the inner peripheral surface of the throttle bore of the part, a ring is installed in the groove to form an annular slit in the inner peripheral surface of the throttle bore, and an annular gas passage communicating with the slit. In the atomization promoting device for a vaporizer, the atomizing gas is introduced into the annular gas passage according to the opening degree of the throttle valve. A small throttle valve for adjusting the gas flow rate is provided in the middle of the gas introduction pipe, and the ring is moved in the axial direction of the throttle bore according to the opening degree of the small throttle valve to adjust the size of the slit. An atomization accelerator for a vaporizer, characterized in that it is provided with a slit adjustment mechanism for adjusting the slit.
