System, for re-injection of exhaust gas into internal combustion engine, has control valve protruding into inlet flow channel, with obstruction placed downstream to create dynamic pressure and to induce radial flow

摘要

The re-injection system is designed for the gas valves of an internal combustion engine, to produce partial re-injection of the exhaust gas into the flow channel (2). The inlet flow (5) is controlled by a valve (9, 19), with its mountings penetrating into the flow section (1) of the flow channel in order to influence the flows (4, 5). An obstructing element (11) is placed in the flow channel at a set distance (18) downstream of the inlet point (10) of the exhaust gas flow, to induce a dynamic pressure and radial flow (15).
