    • The present invention relates to a partial DPF (Partial Diesel Particulate Filter; referred to hereinbelow as a pDPF) device. It is an aim of the present invention to provide a device for reducing smoke in light-oil vehicles for a rapid acceleration response, in which a metal filter, which has been optimally designed for removing particulate matter produced during constant-speed running, is provided with an additional filter constructed in such a way as to minimise the discharge characteristics under rapid acceleration conditions while not greatly increasing the volume. The device for reducing smoke in light-oil vehicles for a rapid acceleration response of the present invention is an exhaust emission control device which is inserted into the exhaust pathway of a diesel engine, characterised in that it comprises: an oxidation catalyst (200) which uses a catalytic reaction to remove some of the harmful substances in the exhaust gas including CO, THC, NOx and SOF; a composite filter (100) which comprises a main filter (110) and a reinforcing filter (120) fitted over the outer circumference of the main filter (110), and which is for removing some of the harmful substances in the exhaust gas including soot; and a case for accommodating the oxidation catalyst (200) and composite filter (100) either integrally or individually, and in that the oxidation catalyst (200) and composite filter (100) are disposed sequentially from the upstream side of the flow of the exhaust gas.
    • 本发明涉及部分DPF(Partial Diesel Particulate Filter; Partial Diesel Particulate Filter;以下称为pDPF)装置。 本发明的目的是提供一种用于减轻轻油车辆中的烟雾的装置,用于快速加速响应,其中设置了用于去除在恒速行驶期间产生的颗粒物质的最佳设计的金属过滤器 具有附加过滤器,其构造成使得在快速加速条件下使放电特性最小化,同时不会大大增加体积。 用于本发明的快速加速响应的用于减轻轻油车辆中的烟雾的装置是一种排气排放控制装置,其被插入到柴油发动机的排气通路中,其特征在于包括:氧化催化剂(200),其 使用催化反应来除去包括CO,THC,NOx和SOF在内的废气中的一些有害物质; 复合过滤器(100),其包括主过滤器(110)和装配在主过滤器​​(110)的外周上的增强过滤器(120),并且用于去除包括烟灰的废气中的一些有害物质 ; 以及用于一体地或单独地容纳氧化催化剂(200)和复合过滤器(100)的壳体,并且氧化催化剂(200)和复合过滤器(100)从排气流的上游侧依次配置 加油站。
