Abstract
A fuel injection apparatus in accordance with the invention has a hot wire type sensor disposed in a bypass air passage and adapted to sense the flow rate of air in the bypass air passage. In order to absorb the pulsation of air flowing in the bypass air passage, the bypass air passage opens at its one end to the air cleaner of an intake system disposed in a portion upstream from the hot wire sensor. An orifice is disposed in a portion of the bypass air passage downstream from the hot wire sensor.
