Claims

[Scope of utility model registration request]

(1) An intake throttle valve is provided in the intake air passageway and controls the amount of intake air, and a fuel injection valve is provided upstream of the intake throttle valve, and the fuel injection amount is adjusted according to the operating state of the engine. In an intake throttle valve control device used in an automobile engine in which the amount of intake air is determined, there is a detection device that detects an operating state with a small amount of intake air and outputs a detection signal, and a detection device that detects an operating state where the amount of intake air is small and outputs a detection signal, and a detection device that detects an operating state where the amount of intake air is small and outputs a detection signal, and a detection device that adjusts the opening degree of the intake throttle valve in response to the detection signal. 1. A control device for controlling an intake throttle valve, comprising: a control device for limiting the intake throttle valve to a predetermined value or less.

(2) Utility Model Registration Scope of Claims 1. In the device according to claim 1, the injection device includes a negative pressure forming section near the injection valve, a port for extracting negative pressure from the negative pressure forming section, and a port for extracting negative pressure from the negative pressure forming section. The restriction device includes an actuator through which the negative pressure is introduced through the passage, and a lever having a stopper portion that rotates together with the intake throttle valve.
When the actuator is connected to the drive ring of the actuator and a negative pressure of a predetermined value or less is introduced into the actuator,
An intake throttle valve control device comprising a lever that abuts against a stopper portion of the lever to prevent rotation of the intake throttle valve so that the intake throttle valve does not fully open.
