Abstract
A connection for an exhaust gas return pipe which includes a duct spirally disposed around an intake pipe of an internal combustion engine. Exhaust gases flow through the duct and enter, from the spiral duct, through overflow openings into the intake pipe so as to enable the exhaust gases to be intensively mixed with the intake air.
