Abstract

The invention discloses a fuel switching device for motorcycle. It includes a fuel electromagnetic valve to control fuel passageway, a fuel electromagnetic for control gas passageway, an oil pump, a switch, a control device, and a fuel indicator light. The control device could control oil pump to open the process of switching from fuel to gas, and pumping the oil in carburetor to fuel tank. The invention also discloses the fuel switching method. The invention could realize stable switching between fuel and gas.

Description

technical field [0001] The invention relates to a fuel switching device and a corresponding switching method for motorcycles or mopeds. Background technique [0002] Due to the relatively bad emissions of gasoline motorcycles and mopeds, which seriously pollute the atmosphere, clean energy vehicles such as liquefied petroleum gas (LPG) have become the mainstream of new transportation tools and have a large market demand in the world. However, the gas refueling of LPG vehicles, especially motorcycles and mopeds, is a big problem, because the government must fund a large number of LPG refueling stations and related facilities, which also creates a major obstacle to the promotion of LPG vehicles . If there is a dual-fuel motorcycle and moped, with LPG as the main fuel and gasoline as the backup fuel, then such oil-gas dual-fuel vehicles can be used in large quantities in cities with fewer gas filling stations, so that users do not have to refuel. Difficult to worry about, but...
