A carburetor structure for preventing oil cut-off in bumpy road sections

ActiveCN110700968BEnsure balanceReal-time sensing of swaying conditionsFloat-controlled apparatusMachines/enginesSuction forceCarburetor
The invention discloses a carburetor structure capable of preventing fuel cut-off in a bumpy section. The carburetor structure mainly comprises an oil crust base, an oil crust, a magnetic induction device and a floater; magnet sheets are symmetrically arranged on the floater, the positions of the magnet sheets on the floater are tracked by using an electromagnetic induction component module through the magnetic induction device arranged on the outer wall of the oil crust, the magnetic induction device slides up and down in a guide rail groove to be matched with the movement of the floater to induce the swing condition of the floater in a real-time manner, then digitized control is performed by an electromagnetic induction processing chip, when the swing frequency of the floater is too high, the electromagnetic induction processing chip sends a command to a chip executor, and power is supplied to an electromagnet at the front end to generate a magnetic attraction force to form magneticattraction with the magnet sheets on the floater to achieve the purpose of control the floater. Through the control to floater fluctuation, oil inlet of a carburetor is not continuously cut off due todrastic fluctuation, and the phenomenon that an engine is flamed out in the bumpy section is avoided.
