    • Described herein are various embodiments of an apparatus and system for trapping debris and arresting sparks that overcomes at least some shortcomings of the prior art approaches. According to one embodiment, an apparatus (230) is disclosed for mitigating failure of an exhaust after-treatment component (210) in an internal combustion engine system (100) capable of generating an exhaust gas stream. The apparatus includes a housing (231) that includes an exhaust inlet (232), exhaust outlet (234), and exhaust flow channel (344) positioned between the exhaust inlet and outlet. Also, the apparatus includes a tubular-shaped mesh screen (236) positioned substantially entirely within the exhaust flow channel. The mesh screen includes a closed end (250) positioned proximate the exhaust inlet of the housing and an opposing open end (342) positioned proximate the exhaust outlet of the housing. The mesh screen is configured to capture failed exhaust after-treatment component particles within the exhaust gas stream.

    • A muffler for coupling to an exhaust port (32) of an internal combustion engine (14) includes a housing (46), a first hollow body (80) within the housing, a catalyzer (82) within the first hollow body, and a second hollow body (84) within the housing. The first hollow body (80) has an inner surface defining a first chamber (106) and an inlet adjacent the exhaust port (32) to admit the exhaust gas into the first chamber. The exhaust gas is exothermally treated as it flows through the catalyst in the first chamber (106) in a direction away from the engine and passes through an outlet of the first hollow body to a second chamber (108). The second chamber is formed by an inner surface of the second hollow body (84) and an outer surface of the first hollow body (80). The treated exhaust gas flows through the second chamber in a direction toward the engine over the outer surface of the first hollow body (80) and passes through an outlet of the second hollow body to a third chamber (110). The third chamber is formed by an outer surface of the second hollow body (84) and an inner surface of the housing (46). The outlet of the second hollow body (84) is provided with louvers (94) for directing the exhaust gas in a direction away from the engine in the third chamber (110). After expanding and mixing in the third chamber, the exhaust gas is expelled from the third chamber through an outlet (68) of the housing adjacent the engine.
    • 用于联接到内燃机(14)的排气口(32)的消声器包括壳体(46),壳体内的第一中空体(80),第一中空体内的催化剂(82)和 第二空心体(84)。 第一中空体(80)具有限定第一室(106)的内表面和邻近排气口(32)的入口,以允许排气进入第一室。 废气在其沿着远离发动机的方向流过第一室(106)中的催化剂时被放热处理,并且通过第一中空体的出口通到第二室(108)。 第二室由第二中空体(84)的内表面和第一中空体(80)的外表面形成。 经处理的废气在第一中空体(80)的外表面上沿着朝向发动机的方向流过第二室,并且通过第二中空体的出口进入第三室(110)。 第三室由第二中空体(84)的外表面和壳体(46)的内表面形成。 第二中空体(84)的出口设置有用于在第三室(110)中沿着远离发动机的方向引导排气的百叶窗(94)。 在第三室中膨胀和混合之后,废气通过邻近发动机的壳体的出口(68)从第三室排出。
