摘要： PURPOSE: To improve a characteristic of muffler in a range of low frequency in the muffler in which an expansion chamber formed between an inlet pipe and an outlet pipe and a resonance chamber are communicated by two conduits, respectively, by a method wherein the inlet pipe is properly arranged with respect to one of the conduits.
CONSTITUTION: The muffler is constructed such that end plates 2, 3 are arranged at both ends of an outer cylinder 1 constituting a main body, three buffle plates 4W6 are mounted witnin the outer cylinder 1, resepctively, and between each of the plates 2W6 are formed the first to third expanison chambers 7W9 and a resonance chambers 10, respectively. Through each of said plates 2W6 are passed the desired inlet pipe 11, inner pipes 12, 13, outlet pipe 14 and the first and second conduits 15, 16, respectively. In this arrangement, said pipe 11 and the conduit 15 are arranged on the same axis with each other, open ends in the expansion chamber 7 are oppositely faced with each other and at the same time a clearance (t) between the open ends is set in a range of 4W7mm. According to this arrangement, it is possible to promote a resonance effect of the resonance chamber 10 and to expect a sound absorption effect in a range of low frequency.

摘要： PURPOSE:To obtain high silent effect by communicating a fluid passage with a cavity chamber by a cylindrical communicating pipe, then providing a piston, controlled in its insertion length according to noise frequency, in the communicating pipe, and forming the cross-sectional form of the piston of a circular arc and a chord of approximately the same diameter as the inner wall of the communicating pipe and also specifying each cross-sectional form. CONSTITUTION:An exhaust passage 1 downstream of a catalytic converter, and a cavity chamber 4 forming a cylindrical closed space are connected by a cylindrical communicating pipe 3. A piston 8 is disposed on the axis of the communicating pipe 3, and the insertion length of the piston is changed by an actuator 10 through a shaft 9. Each cross-sectional form of the piston 8 is formed of a circular arc and a chord of approximately the same diameter as the inner wall surface of the communicating pipe 3, and the maximum distance Zcm from the chord to the circular arc is expressed by an equation in relation to the distance Xcm along the longitudinal length of the piston 8 from its fluid passage 1 side tip, where the radius of the circular arc is Rcm, and the longitudinal length of the piston 8 is Lcm. Resonance frequency is thus made coincide with noise frequency, so that the acoustic resistance of the piston 8 is reduced to obtain high silencing effect.

摘要： PURPOSE:To reduce a noise satisfactorily as suppressing power consumption in the generation of a ripple in a noise reducer in which a ripple with negative phase is superimposed on the noise generated in a fluid path. CONSTITUTION:A diaphragm 8 to supply the ripple to exhaust gas in the exhaust path 1 of an internal combustion engine is fixed on one terminal of a lead spring 10. The leaf spring 10 is supported between a pair of supporting rollers 14 mounted on a movable member 12 for leaf spring supporting. An excitator 16 is assembled in the movable member 12. The position of the movable member 12 is controlled so as to conform the proper frequencies of the diaphragm 8 and the flat spring 10 to the primary frequency of an exhaust noise due to the explosion and burning of an engine main body. The excitator 16 excites the diaphragm 8 so as to be set at the frequency equivalent to the primary frequency component of the noise and also at the negative phase. Amplitude can be amplified by the resonance of an excited diaphragm 8.

摘要： PURPOSE:To prevent any knock being produced in a pin joint part from occurring, in a flexible pipe system for an exhaust pipe. CONSTITUTION:In this flexible pipe device for an exhaust pipe, each of first and second support covers 20, 30 is clamped to both first and second ends 11, 12 of a bellows 10, a pin member 40 is attached to the first support cover 20, a cap member 50 is attached to the second support cover 30, and a load receiving buffer 60 consisting of a wire mesh is interposed between the pin member 40 and the cap member 50, while in parallel with this buffer, two damping buffers 90, 90', having an elastic modulus smaller than this load receiving buffer 60 are interposed between them too. Even if crushing and settling were produced in this buffer 60 due to use for months, any lost motion thereby is absorbable by the damping buffers 90, 90', thus a knock is prevented from occurring.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for reproducing wet road running environment for easily reproducing a splashing state approximately corresponding to such a case in actual running.
SOLUTION: Since a nozzle drive mechanism 25, a nozzle restriction mechanism 27, and a pump drive motor 32 are controlled based on a predetermined water jet condition and then high pressure water is jetted from a nozzle 20 to a test product (a test vehicle 16 or a test exhaust pipe 17), the trace of water splash corresponding to the water jet condition is reproduced on the test product. Performance required for running on a wet road such as waterproof performance or rust prevention performance can be evaluated without running on a test course, and vehicle design requirement can be determined. By avoiding repitition of a plurality of times of tests that may be occurred in water splash reproduction test when the vehicle runs on the test course, product development can be speeded up. Since the reproduction of the water splash condition can be performed without influence of weather, an original test plan is not changed because of bad weather.

摘要翻译：要解决的问题：提供一种用于再现湿路运行环境的方法和装置，用于容易地再现与实际运行中的这种情况大致对应的飞溅状态。解决方案：由于喷嘴驱动机构25，喷嘴限制机构27和泵驱动马达32基于预定的水喷射条件被控制，并且然后将高压水从喷嘴20喷射到测试产品（a 测试车辆16或测试排气管17），在测试产品上再现对应于喷水状态的水飞溅痕迹。可以在无需在测试过程中运行的情况下评估在湿路上运行所需的性能，例如防水性能或防锈性能，并且可以确定车辆设计要求。通过避免在车辆在测试过程中行驶时可能发生的水飞溅再现测试中多次测试的复制，可以加快产品开发。由于可以在不影响天气的情况下进行水飞溅状态的再现，因此天气恶劣的原始测试计划不会改变。版权所有（C）2005，JPO＆NCIPI
