- 1 - Abstract Fuel injection apparatus for an engine includes two intake tubes each having a throttle valve, a fuel injection valve for injecting fuel into each of the intake tubes, a hot-wire air flowmeter for measuring the quantity of intake air sucked into the intake tubes and a by-pass passage accommodating the detection portion of the flowmeter. The by-pass passage has an inlet portion for introducing the static pressure of air flow sucked into each intake tube, a central portion for passing the air introduced from each intake tube and an outlet portion for discharging into each intake tube the air passing through the central portion. The detection portion of the flowmeter is located in the central portion of the by-pass passage. In this way the flowmeter is able to obtain an output relatively undisturbed by air pulsations to obtain improved performance and fuel consumption.
