Claims (1)

[Scope of Claim for Utility Model Registration] (1) In a fuel supply device that calculates the basic amount of fuel to the engine from throttle opening information and engine rotation speed information, the intake passage communicating with the engine is The primary passageway is divided into a primary passageway equipped with a primary throttle valve that operates over the operating range, and a secondary passageway equipped with a secondary throttle valve that operates from a relatively low opening range of the primary throttle valve. 1. A fuel supply system for an internal combustion engine, characterized in that a throttle sensor is connected to at least a primary throttle valve among the valves, the throttle sensor detecting the valve opening and providing opening information. (2) The utility model registration claim 1, wherein the output of the throttle sensor is configured to change to approximately the maximum output when the secondary throttle valve starts operating. Fuel injection system for internal combustion engines.
