ABSTRACT:
Construction of a carburetor used in a stratified charge combustion engine, wherein: flow division control means are dispensed with; and a main and an auxiliary discharge valves are made to have the flow division control functions by themselves, that is, air-fuel ratios of mixtures produced in a main air intake passage and an auxiliary air intake passage, respectively, are adapted to be varied in response to the change of the flow rate of intake air into the associated engine by changing the respective flow rate characteristics of the main and auxiliary discharge valves; thereby eliminating the drawback of decreased accuracy in actual operation of a carburetor used in a stratified charge combustion engine having said flow division control means.
