Abstract
Disclosed is an exhaust gas purifying apparatus for an automobile diesel engine including a pair of electrodes disposed at a predetermined interval in an exhaust path of an automobile diesel engine, and a high voltage power source for applying a high voltage to the pair of electrodes whereby an electric field is generated in a space between the pair of electrodes so as to collect diesel particulates. Since the diesel particulates emitted from a diesel engine are charged heavily in negative, and since the exhaust gas purifying apparatus forms an electric field between the pair of electrodes, the diesel particulates are collected on one of the pair of electrodes. Hence, in accordance with the exhaust gas purifying apparatus, it is possible to purify the exhaust gas without substantially increasing the exhaust gas pressure loss of the diesel engine, without deteriorating the output of the diesel engine resulting from the pressure loss and without deteriorating the combustion reaction in cylinders of the diesel engine. In addition, it is possible to down-size the exhaust gas purifying apparatus remarkably compared with a conventional apparatus employing a ceramic filter.

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.
