Multi cylinder internal-combustion engine, has mixing device attached to return line, where mixing device discharges exhaust gas into suction manifold over openings, and arranged in axial direction of manifold at distance from one another

摘要

The engine (1) has a suction system (3) including a suction manifold (31) supplying fresh mixture (L) to a cylinder (2`), and an exhaust system (4) conducting out an exhaust gas (A) from the cylinder of the engine. A mixing device (54) is attached to a return line (51), where the mixing device discharges the exhaust gas into the suction manifold over several mixing openings. The mixing openings are arranged in an axial direction of the suction manifold at a distance from one another.
