Claims

[Scope of utility model registration request]

In an internal combustion engine having multiple cylinders, a fuel injection valve is provided upstream of the branching part of the intake passage to each cylinder, and a primary throttle valve and a secondary throttle valve are arranged in parallel upstream or downstream of the fuel injection valve. The intake passage downstream of the throttle valve is divided into two systems, a primary intake passage and a secondary intake passage, which communicate with the above-mentioned secondary throttle valve, respectively, up to the vicinity of the intake valve, and the intake air amount is compared. When the engine is running at low speed and with a low load, the entire amount of fuel injected from the fuel injection valve and the intake air are supplied to the engine through the intake passage on the downstream side. A mixture supply device for an internal combustion engine, characterized in that the mixture is supplied to the engine through the air-fuel mixture.
