摘要

The device has a fresh air intake tube (1), a re-circulated exhaust gas intake tube (2) and an exhaust gas collector from which the tube (2) is branched. The tube (1) is connected to cylinders (C1, C2) of an internal combustion engine e.g. oil engine, by using a distributor (7) with its branches (7A, 7B), by intake valves (3). The tube (2) is connected to the cylinders by a distributor (8) with its branches (8A, 8B), by valves (4). The tube (2) has a throttle (6) controlling a passage between the tubes (1, 2). A throttle (9) is placed in the tube (1) upstream the throttle (6).
