Abstract
In a fuel supply apparatus for an internal combustion engine, a fuel discharging apparatus includes a fuel discharge port opened in an air intake conduit and a fuel valve for injecting a controlled quantity of fuel into the air intake passage through the discharge port. An annular fuel whirling chamber is formed around the fuel valve to receive fuel flow in a tangential direction to cause the fuel flow to whirl within the annular chamber. On the other hand, an annular recess is formed in a passage communicating the discharge port and the fuel valve with each other to forcively feed air to the fuel flowing through the passage. The fuel is thus intensively mixed with air and can be easily atomized upon being injected into the air intake passage through the discharge orifice.
