TLDR
In this article, an exhaust gas recirculation manifold (EGR) is proposed to deliver recirculated exhaust gas within the flowpath of the intake manifold, and both linear and round shapes are considered for the EGR manifold.Abstract:
An exhaust gas recirculation (EGR) manifold received within an intake manifold. The EGR manifold includes a plurality of holes for delivery of recirculated exhaust gas within the flowpath of the intake manifold. Both linear and round shapes are contemplated for the EGR manifold.read more

Apparatus for supply of recirculated exhaust gas
TL;DR: In this article, the authors describe an apparatus and a process for supplying recirculated exhaust gases to incoming air to a piston-type internal combustion engine. But their work is limited to the case where the feed pipe opens out into an outlet section comprising a t least one outlet for the supply of the exhaust gases.

Systems and methods for exhaust gas recirculation
TL;DR: In this paper, an exhaust gas recirculation system is further coupled between the second exhaust manifold and the intake passage, and the number of openings equal to or greater than a number of cylinders having an intake event between successive exhaust events occurring in the second cylinder group.
Patent
Systems and methods for exhaust gas recirculation
TL;DR: In this paper, a mixer pipe is used to mix exhaust gas recirculation (EGR) gases exhausted by the second cylinder group that are delivered through the second exhaust manifold with inlet air.

Intake device for an internal combustion engine
Andreas Grüner,Robert Sendor +1 more
TL;DR: In this article, an induction unit has at least one fresh gas distributor to supply air to several cylinders, with a fresh air outlet for each cylinder alongside each other, and a distribution channel from an exhaust gas return device (12) is fitted to the fresh air distributor alongside all the fresh gas outlets and communicating with the new gas distributor.
Patent
Fluid feed duct for a hot fluid in a hollow structure
TL;DR: In this article, a fluid feed duct, consisting of a hollow structure into which a feed connection is introduced by means of a joint structure, is used for feeding a recirculated waste gas stream (broken arrow) into a stream of admission air (continuous arrow) in an internal combustion engine.

Exhausted gas recycle device
TL;DR: An exhausted gas recycle device which is installed in an intake manifold is comprised of an inlet portion which penetrates into the intake manifold and communicates with an exhaust manifold and at least one hole formed on the inlet part in the manifold.
Patent
Exhaust gas return pipe connection for an internal combustion engine
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.
Patent
Exhaust gas recirculation system for an internal combustion engine
TL;DR: In this article, the response accuracy of the throttle valve is protected from being impaired due to deposition of exhaust gas contaminants thereon, and the exhaust gas recirculation system comprises first means for conducting a portion of the exhaust gases from the exhaust passage into the intake passage downstream of the throttles, and second means for preventing exhaust gases fed through said first means from flowing upstream toward the throttle valves.
Patent
Pollution control device
TL;DR: In this article, a reed valve is used to precisely measure the flow of exhaust gases and/or ambient air in response to atmospheric pressure, intake manifold pressure and exhaust manifold pressure.
