Exhaust manifold of a turbo-supercharged reciprocating engine

Exhaust manifold (11) of a turbo-supercharged Diesel engine with any number of cylinders ranging from 2 to 6 and equipped with an EGR system, which comprises at least one particle filter (45) for retaining the particles contained in the exhaust gases, characterized in that it includes:

• a) an outer casing (21) which includes flanges (23, 25) for effecting joining, respectively, to the cylinder head (13) of the engine and the turbine (15) and an opening towards an EGR outlet duct (27) and an inner wall (31), substantially parallel to the area of the outer casing (21) located between the flanges (23, 25) and with low thermal inertia than the outer casing (21), defining a regulating chamber (33) for the exhaust gases introduced into it via a plurality of orifices (35) located in the inner wall (31) downstream of said at least one particle filter (45);
• b) inner branches (41) for entry of the exhaust gases, situated opposite the exhaust pipes (17);
• c) an outlet duct (59) for conveying the exhaust gases to the turbine (15), designed as an extension of the inner wall (31).
