ABSTRACT:
In a device for controlling the temperature of the intake air to an internal combustion engine, the piston of a hydraulic cylinder controls the setting of a damper between the warm-air intake and the cold-air intake. A sensor body in the mixed-air duct communicates, via a hydraulic conduit, with the cylinder. The sensor body is filled above a free piston with an expansion medium of higher coefficient of thermal expansion than the hydraulic medium on the opposite side of the free piston. By allowing the temperature in the engine compartment, for example, to determine the temperature of the hydraulic conduit, the control interval is displaced so that the temperature of the intake air is higher when the engine is cold than when it is warm.
