  "textContent": "An air intake apparatus of a multi-cylinder engine includes an intake air inlet passage, an intake air distribution portion, a plurality of independent intake air passages, and a secondary gas inlet passage. The intake air inlet passage has one end portion attached to a throttle valve, and the other end connected to an intake air distribution portion. The intake air distribution portion has a space therein. The secondary gas inlet passage is connected at a part spaced apart, in the intake air inlet passage, from the throttle valve. The intake air distribution portion has a reflux passage which is a passage that connects the space and a part between the one end portion and the other end in the intake air inlet passage. The reflux passage is a passage which refluxes fresh air and secondary gas introduced from the intake air inlet passage to the intake air inlet passage.",
