Method and device for controlling switchover of binary fuel
专利汇可以提供Method and device for controlling switchover of binary fuel专利检索，专利查询，专利分析的服务。并且PURPOSE: To restrain variation in air-fuel ratio at the time of changing a mode by feeding a small quantity of liquid fuel corresponding to one at the time of idling for a certain period of time when switching over binary fuels which are fed to an engine.
CONSTITUTION: A bomb 1 filled with a compressed natural gas (CNG) is connected to the mixing chamber 26 of an intake passage 11 via a cut-off valve 4, regulators 6, 7, and a variable orifice 10. Also, a gasoline tank 2 is connected to an injector 19 via a filter 18. These cut-off valve 4, variable orifice 10, and injector 19 are controlled by a CNG control circuit 13 and a gasoline fuel control circuit 22. And, when switching over the feeding fuels, a small quantity of gasoline corresponding to one at the time of idling is fed from the injector 19 for a certain period of time. Thereby, an air-fuel ratio can be prevented from becoming overly thick or overly thin at the time of switchover.
