摘要： An air intake silencer (30) includes an air inlet pipe (32) and at least one tuning tube (44) in fluid communication with the air inlet pipe. A first length and second length of the air inlet pipe and the tuning tube, respectively, are selected to produce one-half wavelength cancellation of a selected frequency of engine noise. A plurality of tuning tubes (44, 72) located in a wrap-around relationship with on another may tune different frequencies of noise in a compact silencing unit. The air inlet pipe and tuning tube may be integrally fromed into an air intake manifold that silences one or more engine air intake inlets, and the air intake silencer may be integrated into a motor cover.

摘要： As a result of manufacturing tolerances, turbochargers in internal combustion engines produce a noise which depends on the engine speed and, depending in the charger, is disturbing mainly in the lower kHZ range. The object of the invention is to reduce the sound of this background noise which occurs when the vehicle is in operation. According to the invention the air inlet duct (1) between the turbocharger and the internal combustion engine is internally provided with screens or walls (5) the openings (8) of which are at least the internal diameter of the inlet (3) and of the outlet (4) and align therewith. The spaces (10) between the screens (5) form for the air flowing therethrough resonance chambers which, by choosing different opening diameters (8) and/or different screen distances, can be tuned over a broadband for a damping of in excess of 20 dB(A) in the range from 1 kHZ to 5 kHZ. The reflection silencer is used in motor vehicles.

摘要： An air plate for making gas and fuel oil mix completely in an internal combustion engine includes a main body, which body has excellent vibratility and is provided with several air-guiding members. Flowing passages of the air-guiding members are formed in such manner that both sides progressively become big toward outside. Cervixes with small sections are formed in the middles of the flowing passages, and the flowing passages go through the air plate. As the main body has excellent vibratility and the air-guiding members are provided with the flowing passages which are enlarged or shrinked symmetrically, resonance is generated when the flow of air flows through the air plate, as a result, the speed of air and the resonant frequency of flowing air are increased, therefore the air density is optimized. As the flow of air flows through air cleaner and air plate, the combustion is performed completely and uniformly and fuel oil is saved.

摘要： A butterfly valve noise suppressor (10) is provided for reducing the noise generated by a gas flow passing through an open butterfly valve having a disc (16) pivotally mounted in a valve housing (12) for rotation about a transverse axis between an open and a closed position thereof. The noise suppressor (20) includes a plurality of flat and perforated baffle plates (22) arranged in a cruciform configuration, mounted in a flow path immediately downstream of the pivotal disc, axially extending and thereby dividing the downstream flow path into four axial and quadrant cross-sectional segments (24). The gas flow passing the edge of the pivotal disc in the valve generates a flow turbulence to form an unsteady large wake downstream of the valve. This unsteady wake is the source of noise. The cruciform baffle plates (21) permit the gas flow to pass therethrough without obstruction thereto, while allowing the turbulence to communicate laterally through the perforation (26), thereby dissipating the wake unsteadiness to reduce noise. The butterfly valve noise suppressor according to the present invention provides a better acoustic result compared to a muffler used in a conventional butterfly valve, and is lighter, durable, simpler and more economical to manufacture.
摘要翻译：提供了一种蝶形阀噪声抑制器（10），用于减少通过打开蝶形阀的气流产生的噪音，所述蝶形阀具有枢转地安装在阀壳体（12）中的盘（16），用于围绕横向轴线在打开其关闭位置。噪声抑制器（20）包括以十字形构造布置的多个扁平且穿孔的挡板（22），所述挡板安装在紧靠枢转盘的下游的流动路径中，轴向延伸并由此将下游流动路径分成四个轴向和四分之一圆横截面片段（24）。通过阀中枢转盘边缘的气流产生流动湍流，以在阀的下游形成不稳定的大尾流。这种不稳定的尾流是噪音的来源。十字形挡板（21）允许气流通过，而不阻碍气流，同时允许紊流横向穿过穿孔（26），从而消除尾流不稳定以减少噪音。与传统蝶形阀中使用的消声器相比，根据本发明的蝶形阀噪声抑制器提供了更好的声学效果，并且更轻，更耐用，更简单且更经济地制造。

摘要： The filter silencer, mounted on the inlet side of a compressor, comprises a support body (1), several damping elements in the form of noise damping blocks (2) and a filter frame (3), arranged around the circumference of the silencer. The filter frame (3) is in the form of a perforated sheet. Several throughflow openings (11) are let into the noise damping blocks (2). The noise damping blocks may be prefabricated in the form of a complete unit and may be simply assembled and disassembled. The number of components for the filter silencer is thus reduced, which reduces logistical demands and thus permits an economical production and maintenance of the filter silencers.

摘要： An air resonator system for a vehicle has a variable volume to reduce noise expected at both high and low speeds. In one embodiment, a pair of necks (28, 32) communicate with chamber portions (30, 31). A valve (38) selectively blocks communication between the chamber portions (30, 31) and allows each of the necks to communicate with the relatively small volume chamber portions. This position is particularly good for reducing the high frequency noise expected at high engine speeds. The valve (38) is movable to a second position at which it allows communication between the two chamber portions and blocks communication between one of the necks and its respective chamber portion. The relatively large chamber volume provided at this position is particularly well suited for reducing the low frequency noise expected with low engine speed. Thus, a single air resonator system is provided which can be adjusted to accommodate noise at both high and low speeds.
摘要翻译：一种用于车辆的空气谐振器系统具有可变容积，以减少在高速和低速下预期的噪声。在一个实施例中，一对颈部（28,32）与腔室部分（30,31）连通。阀（38）选择性地阻挡腔室部分（30,31）之间的连通并且允许每个颈部与相对较小体积的腔室部分连通。该位置对于降低在高发动机转速下预期的高频噪声特别有利。阀（38）可移动到第二位置，在该第二位置允许两个室部分之间的连通，并阻止颈部和其相应的腔室部分之间的连通。在该位置处设置的相对较大的室容积特别适合于降低低发动机转速所预期的低频噪声。因此，提供单个空气谐振器系统，其可以被调节以适应高速和低速的噪声。
