ABSTRACT:
A device is provided for controlling the flow of the exhaust gases of an internal combustion engine in accordance with the operating conditions of the engine. Exhaust gases flowing from the exhaust manifold are routed either directly to the muffler or to a heat exchanger for preheating the intake air/fuel mixture. The device includes an aeromechanical element having a nozzle-like constriction opening into an enlarged passage. A pair of outlets, connected to the muffler and heat exchanger, branch off from the passage following the constriction. The flow of gases is selectively directed through one of the two outlets by means of control line connections in the enlarged passage, which are supplied with either pressure, negative pressure, or both as the means for deflecting the flow.
