The purpose of the present invention is, in a configuration in which fuel is injected by an injector, to simplify and reduce the size of the configuration, to realize atomization of spray fuel in accordance with the operating state of an internal combustion engine, and to suppress or prevent adhesion of fuel to the wall surface of an intake passage. A fuel injection and intake device includes: an intake passage (12) leading to an intake valve of an internal combustion engine; an injector (30) that injects fuel into the intake passage; first auxiliary air passages (41b, 42b) for supplying auxiliary air in the vicinity of the injector; second auxiliary air passages (41b, 43b) for supplying auxiliary air between the injector and the intake valve; and an adjustment valve (50) that adjusts the flow rate ratio of the auxiliary air flowing through the first auxiliary air passages and the second auxiliary air passages. 本发明在利用喷射器来喷射燃料的结构中，实现结构的简化、小型化，并且根据内燃发动机的运转状态来实现喷雾燃料的微粒化，且抑制或防止燃料附着于吸气通路的壁面。燃料喷射吸气装置包括：吸气通路(12)，通向内
