摘要： A filter for washing and retaining exhaust gases in motor vehicles includes one or more chambers formed by either a single chamber with a plurality of sections formed by partitions therein or by separate chambers. Each chamber is provided with an exhaust gas inlet pipe for exhaust gases that have already been partially filtered in a previous chamber or section, or, in the case of a first chamber or section, exhaust gases coming directly from the engine of the motor vehicle. The gases are injected into a filtering liquid by diffusing pipes in the chambers. The exhaust gases are filtered by the filtering liquid as they flow through the liquid, passing afterwards to a subsequent chamber or section, or to the atmosphere through an exhaust outlet. In order to prevent the gases from tending to carry the filtering liquid out of the chambers when passing through the chambers, the chambers are provided with a series of perforated plates that hinder the passage of bubbles of the filtering liquid that may be formed therein. Further, the last chamber or section has at its outlet a decompression chamber having a return conduit for returning liquid to the chambers. The filter is also provided with filling and drainage orifices for cleaning and maintaining the filter.
