Claims

[Scope of claim for utility model registration] A fuel injection valve that supplies fuel to the engine, an intake throttle valve that is installed in the intake passage and controls the amount of intake air supplied to the engine, and intake air above and downstream of the intake throttle valve. A fuel supply device for an internal combustion engine, comprising a bypass passage communicating with the passage, and an intake throttle valve provided above the intake throttle valve in parallel with the bypass passage.
A sub-bypass passage that communicates with the downstream intake passage, a venturi installed in the sub-bypass passage, a fuel supply passage for low-temperature starting whose downstream end opens at the throat of the venturi, and an intake air temperature control passage. or a temperature sensor for detecting temperature related thereto; a start detection device for detecting when the engine is started; a switching valve device that opens a supply passage and a sub-bypass passage;
A fuel supply device for an internal combustion engine, characterized by comprising:
