Claims

[Scope of utility model registration request]

a first fuel supply means that is provided at a relatively upstream position of the intake passage and supplies the basic component fuel; and a first fuel supply means that collects and collects unvaporized fuel collected on the wall surface of the intake passage downstream of the first fuel supply means. a storage tank having a fuel liquid level detection means;
a second fuel supply means provided near the combustion chamber and for supplying the collected fuel of the storage tank; an on-off valve for opening and closing the fuel inlet of the second fuel supply means; and a valve provided in the cooling water passage of the engine. The required fuel amount is calculated based on the detected water temperature sensor and the engine operating state, and the supply amount ratio of the first and second fuel supply means is calculated based on the engine load, the cooling water temperature, and the liquid amount in the storage tank. A fuel supply device for an internal combustion engine, comprising: a control circuit that controls and opens and closes the on-off valve based on a signal from the water temperature sensor.
