<P>PROBLEM TO BE SOLVED: To provide a fuel injection device capable of mixing fine bubbles into fuel by a simple structure. <P>SOLUTION: In the fuel injection device 1, a fuel pump 40 supplies the fuel reserved in a fuel tank 10 together with gas to an injector 61. A gas supply passage member 24 has a gas supply passage 25 for supplying gas containing vaporized fuel reserved in a canister 17 and gas flowing from an inflow passage 22 to the fuel pump 40. A fine bubble mixer 50 causes the gas supplied together with the fuel to be finer and mixed into the fuel. A return passage member 64 has a return passage 65 for returning the fuel in a delivery pipe 60 to the fuel tank 10. A relief valve 67 changes over the connection and disconnection of the delivery pipe 60 and the return passage 65. Thus, the canister 17 serves both to supply the gas into the fuel and to collect and reuse the vaporized fuel, thereby dispensing with a deaerator. Therefore, the fine bubbles can be mixed into the fuel with by the simple structure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
