<p>A vehicle muffler with reducing exhaust gas includes a casing. An air inlet pipe (6) is set on the front end of the casing (4) and an air exhaust pipe (7) is set on the rear end of the casing (5). Several levels of partition boards of the muffler pipes (9) are parallel in the casing. The constructions of the partition boards of the muffler pipes (9) are same or different. Wherein the partition board of the muffler pipe (9) is composed of at least one partition board (2) having several install holes and the muffler pipe (1) corresponding to the number of the installing holes. Several leaving air feedback pipes (8) are arranged between the partition boards of the muffler pipes (9). Air holes (21) are equably distributed on every level of the single partition board or the rear partition boards of the double partition boards expect the first level partition board of the single partition board and the front partition board of the double partition board. The vehicle muffler with reducing exhaust gas improves the manufacture and reduces the cost and improves the produce efficiency and the effect of reducing exhaust gas.</p> |
