The present invention relates to a multifunctional module for an internal-combustion engine, forming a structural assembly and incorporating the functions of cooling the exhaust gases, regulating the re-injection of the exhaust gases and regulating, at least in part, the circulation flows in the cooling circuit of said engine, said structural assembly being in the form of a constructional and functional unit intended to be fitted to the engine block and incorporating, on the one hand, at least a portion of an exhaust gas recirculation circuit and a heat exchanger for cooling said gases and, on the other hand, at least a portion of the engine cooling circuit, with at least the water-outlet housing, multifunctional module characterised in that the heat exchanger has a tank arranged in the region of an end of the constructional and functional unit and made from a synthetic thermoplastic material.

Multifunctional module for an internal-combustion engine

A multifunctional module for internal combustion engine, forming a structural assembly and incorporating the functions of exhaust gas cooling and regulation, at least in part, of the circulation flows in said engine's cooling circuit, comprising a first functional unit incorporating, on the one hand, a part at least of an exhaust gas recirculation circuit and a heat exchanger for cooling the gases, preferably of elongated form, together with at least one gas flow regulation/diversion component, and, on the other hand, a part at least of the engine cooling circuit, with at least the water outlet casing and a thermostatic component for regulating the flow therein; the structural assembly comprises a second functional unit in the form of a substantially flat, plate-shaped body, consisting of a stiffening and fixing plate for the first functional unit and a thermal isolation interface between the first functional unit and the engine block; the plate-shaped body comprises on one of its faces sites for fitting and fixing the first functional unit and on the other face sites for fitting and fixing on the engine block.
