<P>PROBLEM TO BE SOLVED: To provide a fuel supply system correctly estimating fuel property in the injector connection of a pipe supplying fuel from a fuel tank to an injector. <P>SOLUTION: Cells are formed by equally dividing fuel pipe volume from an ethanol concentration sensor 4 to the injector 10 into n+1, and ethanol concentration data as fuel property values stored in the cells are moved to the adjacent cell on the side of the injector 10 every time the fuel consumption C of an engine 1 reaches volume F of one cell. Only when the concentration α0 of the cell A0 connected to the injector 10 is moved to the adjacent cell A1, the concentration of the cell A1 after movement is calculated in a manner that a value with a difference between an original concentration α0 and an original concentration α1 multiplied by a correction coefficient K is added to the original concentration α1 of the cell A1. Thereby, even if the ethanol concentration is suddenly changed, the ethanol concentration of the cell An as the cell at the end of the injector 10 is calculated with high accuracy. <P>COPYRIGHT: (C)2010,JPO&INPIT

16 Carburetor for internal combustion engine JP12325994 1994-05-13 JPH06346798A 1994-12-20 JIYOOJI EI BOSUUERU
PURPOSE: To enhance the air velocity at high speed and improve the fuel feeding by arranging an air flow surface having prescribed aerodynamic characteristics and a fuel feeding orifice communicating with a fuel supply source via a conduit adjacent to a throat part in a venturi of a carburetor. CONSTITUTION: A venturi 10 of a carburetor has a sidewall 12 partitioning a flow passage 14 extending between an inlet 16 and an outlet 18. A throat part 20 is formed in the intermediate part of the flow passage 14. In this case, an air flow surface 26 having prescribed aerodynamic characteristics and a fuel feeding orifice 28 communicating with a fuel supply source 30 via a conduit 38 are arranged in the sidewall 12 adjacent to the throat part 20. The air flow surface 26 is formed of an upstream part 32 positioned in the edge, a downstream part 34 positioned opposed thereto, and a surface part 36 positioned between them. This constitution can enhance the speed of the velocity of the air and improve the feeding of the fuel.
