摘要
In a supercharged engine, a bypass connected to the compressor delivery pipe (4) supplies the turbine with all the air which has not been absorbed by the engine. The bypass (4) is divided into a first branch which supplies combustive air to the primary region (10) of an auxiliary combustion chamber and a second branch which supplies diluting air to the secondary region of the aforementioned chamber and comprises first throttle means. The first branch has second throttle means (13) comprising coupled orifices (14, 15) formed respectively on an inner sleeve (16) and an outer sleeve (17) movable relative to one another. According to the invention, a radial clearance (a) is maintained between the sleeves (16, 17) irrespective of their respective temperatures. Third throttle means (45), having a zero minimum flow section, are provided upstream or level with the second means (13).
