Abstract: An exhaust gas re-induction apparatus includes conduits and an outer housing, which receive exhaust gas from an exhaust system of an engine, and passively recirculate a portion of the gas to an air inlet of the engine while transferring another portion of the gas through orifices in the apparatus and via a return conduit to the exhaust manifold. An exchange of heat occurs between the exhaust gas, the various components and chambers of the re-induction apparatus, and the environment. Fuel efficiency is increased and harmful toxins and emissions are reduced. A system includes the re-induction apparatus and a recirculation conduit, which connects the re-induction apparatus to the air inlet of the engine before the vacuum, via a water separator or soot filter device depending on engine type. The amount of exhaust gas recirculated can essentially depend on the operating speed of the engine and the size dimensions of the apparatus.

Abstract: An exhaust gas re-induction apparatus and system. The exhaust gas re-induction apparatus is coupled to an exhaust system or catalytic converter of an engine. The exhaust gas re-induction apparatus includes an oxygen sensor substitute apparatus having an exhaust gas diffusion chamber disposed therein, and an exhaust gas interface housing to receive the oxygen sensor substitute apparatus. A recirculation conduit connects the exhaust gas re-induction apparatus to an air inlet of an engine. The oxygen sensor substitute apparatus includes a coupling section to attach the oxygen sensor substitute apparatus in place of an oxygen sensor apparatus. The oxygen sensor substitute apparatus also includes an exhaust gas dispersion section having a plurality of orifices for dispersing exhaust gas. The exhaust gas re-induction apparatus and the recirculation conduit have always-open passages in which the exhaust gas is recirculated to the engine at different rates depending essentially on the operating speed of the engine.
