Abstract

FIELD: mechanical engineering; automotive engines. SUBSTANCE: muffler has cylindrical housing 1 with end face walls 2 and 3, intake branch pipe 4, outlet branch pipe 5, central perforated tube 6 connected with branch pipes 4 and 5, cross perforated partition 7 with holes 8 placed between tube 6 and inner surface of housing 1, cross stopper 9 placed in tube 6 in plane of perforated partition 7, and perforated case 10 with holes 11. Novelty is than holes 12 of tube 6 are made over entire length of tube, and case 10 encloses tube 6 over its entire length, being mounted on walls 2 and 3 and partition 7. Holes 11 are made in form of belts whose center, with due account of dynamic increment, is arranged at a distance equal to half the length or quarter the length of corresponding chamber 13 or 14. Other design versions can be made. EFFECT: enhanced efficiency of noise suppression. 2 cl, 6 dwg

Изобретение относится к автомобилестроению, а именно к конструкциям глушителей выхлопа для автомобильных двигателей. Цель изобретения - повышение эффективности заглушения шума. Глушитель содержит цилиндрический корпус 1 с торцевыми стенками 2 и 3, впускной 4 и выпускной 5 патрубки, центральную перфорированную трубу 6, соединенную с патрубками 4 и 5, поперечную перфорированную перегородку 7 с отверстиями перфорации 8, размещенную между трубой 6 и внутренней поверхностью корпуса 1, и поперечную заглушку 9, размещенную в трубе 6, в плоскости перфорированной перегородки 7, а также перфорированный кожух 10 с отверстиями перфорации 11. Новым является то, что отверстия 12 трубы 6 размещены по всей ее длине, и кожух 10 охватывает по всей длине трубу 6 и смонтирован на стенках 2 и 3 и перегородке 7. Отверстия перфорации 11 выполнены в виде поясов, центр которых с учетом динамического приращения размещен на расстоянии половины или четверти длины соответствующей камеры 13 или 14. Возможны варианты конструктивного изготовления глушителя. 1 з.п.ф-лы, 6 ил.

The invention relates to the automotive industry, and in particular to designs of exhaust silencers for automotive engines. The purpose of the invention is to increase the efficiency of damping noise. The muffler comprises a cylindrical body 1 with end walls 2 and 3, inlet 4 and outlet 5 nozzles, a central perforated pipe 6 connected to the nozzles 4 and 5, a transverse perforated partition 7 with perforation holes 8, located between the pipe 6 and the inner surface of the housing 1, and a transverse plug 9, located in the pipe 6, in the plane of the perforated septum 7, as well as the perforated casing 10 with perforation holes 11. It is new that the holes 12 of the pipe 6 are placed along its entire length, and the casing 10 covers all over the length of the pipe 6 and is mounted on the walls 2 and 3 and the partition 7. The perforation holes 11 are made in the form of belts, the center of which, taking into account the dynamic increment, is located at a distance of half or a quarter of the length of the corresponding chamber 13 or 14. Variants of the muffler construction are possible. 1 C.p. f-ls, 6 ill.
