Claims

[Claim for Utility Model Registration] A first throttle valve that starts opening in the low load range of the engine, a second throttle valve that starts opening in the medium and high load range, and a throttle valve that is connected downstream of both throttle valves. An electronic control system comprising a collector, an intake branch that branches from the collector and communicates with the combustion chamber of each cylinder via an intake port, and a fuel injection valve provided near the connection between the intake branch and the intake port. In an intake passage device for an internal combustion engine with a type fuel injection device, an intake passage is provided downstream of the first throttle valve to guide the entire amount of intake air passing through the throttle valve to the outside of the collector, and a downstream end of the intake passage is provided. , communicates with an intake heating chamber provided with a predetermined heating means disposed so as to straddle each intake branch connected to each cylinder, and communicates the intake flow path of this intake air heating chamber with each of the above-mentioned intake branches, respectively. Electronic control characterized by: Intake passage device for internal combustion engine with type fuel injection device.
