Claims

[Scope of utility model registration request]

A swirl control valve is installed in the intake passage of the cylinder head and produces greater intake turbulence on the fully closed side depending on the opening degree, and negative pressure drives the swirl control valve in the valve closing direction as the negative pressure increases. An intake control device for an internal combustion engine comprising an actuator,
A first negative pressure passage introduces negative pressure from a port provided in the intake passage downstream of the throttle valve, and a port located downstream of the throttle valve when the throttle valve is fully closed, and negative pressure from a port located upstream of the throttle valve when the throttle valve is open. and a temperature-sensitive control valve that connects the first negative pressure passage at low temperatures and the second negative pressure passage to the negative pressure operating chamber of the negative pressure actuator at high temperatures depending on the engine temperature. An intake control device for an internal combustion engine, characterized by:
