Exhaust gas purifying apparatus for automobile diesel engine
 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.
