Abstract

In an internal combustion Diesel engine, a conduit (8) for re-circulation of the exhaust gases into the intake manifold (4) opens on an annular chamber (9) surrounding a portion (10) of the inlet conduit (5) of the intake manifold (4) which is communicated to the latter through a plurality of apertures (11). Preferably this conduit portion (10) of the intake manifold is in form of a Venturi conduit.
