Abstract
An exhaust gas treatment system and method, primarily for a motor vehicle having an internal combustion engine. An expansion chamber is connected in a straight line to a first straight line portion of an exhaust conduit from the engine, with a second portion of the exhaust conduit extending in a straight line from the expansion chamber. The expansion chamber has a cross-sectional area 110% to 200% as large as the cross-sectional area of the exhaust conduit. First and second series of openings are provided in the expansion chamber substantially 180.degree. apart along the circumference of the expansion chamber, with the expansion chamber being mounted so that a plane containing the first and second series of openings is generally vertical. Pick-off conduits return carbon monoxide, hydrocarbon gases, and water vapors separated through the openings of the expansion chamber to the engine, the returning gases being filtered to at least remove the excess liquid therein. The excess liquid is vaporized, and the vapor is returned to the intake manifold of the engine, along with the hydrocarbon and/or carbon monoxide gases, which have a relative humidity of 60 to 100% wind return.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
