摘要： A sound-attenuating muffler having a muffler housing with a volume displacement to engine displacement ratio of less than 8:1 and a width to height ratio between 1.05:1 - 3.5:1. The muffler also includes a partition configured to divide the muffler housing into separate compartments, the partition also having a partition opening for the passage of exhaust gases therethrough. A deflection element is attached to an upstream side of the partition along its width and height thereby provide at least one side opening on each side along the width and at least one end opening on each end along the height for the passage of exhaust gases therethrough. A ratio of the open area of both the end openings to the open area of the partition opening is between 0.7:1 - 3.7:1 and a ratio of an open area of both side openings to the open area of the partition opening is between 0.3:1-3.5:1.
摘要翻译：一种具有消音器壳体的声音衰减消声器，该消声器壳体的体积位移与发动机排量比小于8:1，宽与高之比为1.05:1至3.5:1。消音器还包括隔板，隔板被构造成将消音器壳体分成独立的隔间，隔板还具有用于废气通过的分隔开口。偏转元件沿着其宽度和高度附接到分隔件的上游侧，从而沿着宽度在每侧上提供至少一个侧开口，并且在沿着高度的每个端部上的至少一个端部开口用于使废气通过其中。两个端部开口的开口面积与分隔开口的开放面积的比率在0.7:1至3.7:1之间，并且两个侧面开口的开口面积与分隔开口的开放面积之比为0.3 ：1-3.5：1。

摘要： The present invention relates to an improvement muffler that includes an improved inlet configuration having first and second sequential chambers with a perforated central pipe passing longitudinally through a central region of both chambers for directing the exhaust gases into the third chamber in which the deflection element is deployed. Additionally, the partition separating the first and second chamber has a hole that enables some of the gas to pass from the first chamber into the second chamber not through the central pipe.
摘要翻译：本发明涉及一种改进的消声器，其包括具有第一和第二连续腔室的改进的入口构造，所述腔室具有纵向穿过两个腔室的中心区域的穿孔中心管，用于将废气引导到第三腔室中，偏转元件部署在其中。此外，分隔第一和第二室的隔板具有使得一些气体不能通过中心管从第一室进入第二室的孔。
