摘要： PROBLEM TO BE SOLVED: To reduce noises in a stainless steel double exhaust pipe by improving vibration transmitting system which may cause radiation noises from an outer pipe. SOLUTION: An exhaust manifold has an inner pipe 7 fixed to a flange 4, and an outer pipe 8 arranged outside thereof. A support pipe 9 having a longitudinal slit is fitted to a connection position of the inner pipe 7 and the outer pipe 8. The support pipe 9 is in surface-contact with an outer peripheral surface of the inner pipe 7, while the outer pipe 8 is in surface-contact with the outer periperal surface of the support pipe 9. The inner pipe 7 is oscillated by pulsation of exhaust gas. The oscilation is, however, frictionally damped by the surface contact portion of the support pipe 9 and then transmitted to the outer pipe 8. Generation of radiation noises from the outer pipe 8 is thus suppressed.

摘要： PROBLEM TO BE SOLVED: To inhibit whirl noise in a turbocharger of a structure supporting a turbine shaft by a floating bush bearing. SOLUTION: Oil supply passes (an oil passage 11 and an oil supply hole 13, an oil passage 12 and an oil supply hole 14) for individually supplying oil of different pressure to a floating bush bearing 7 on a turbine side and a floating bush bearing 8 on a compressor side are provided to keep pressure of oil supplied to the floating bush bearing 8 on the compressor side higher than pressure of oil supplied to the floating bush bearing 7 on the turbine side, and to keep a spring constant of oil film in the floating bush bearing 8 on the compressor side larger. Consequently, whirl noise due to self-excited vibration of a cylinder mode is not easily generated since run out quantity on the compressor side of the turbine shaft 3 is reduced by adjusting the spring constant of oil film of the floating bush bearings 7, 8.

摘要翻译：要解决的问题：通过浮动衬套轴承来抑制支撑涡轮轴的结构的涡轮增压器中的涡流噪声。
解决方案：供油通过（油路11和供油孔13，油路12和供油孔14），用于单独地将不同压力的油供给到涡轮机侧的浮动衬套轴承7和设置浮动衬套轴承8在压缩机侧，以保持供给到压缩机侧的浮动衬套轴承8的油的压力高于供应到涡轮机侧的浮动衬套轴承7的油的压力，并且保持弹簧常数为油膜在浮动衬套轴承8上的压缩机侧较大。因此，由于通过调整浮动衬套轴承7,8的油膜的弹簧常数，不容易产生由于气缸模式的自激振动引起的涡流噪声，因为涡轮轴3的压缩机侧的流出量减少。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a variable valve train capable of preventing a variation in valve lift adjustment amount between cylinders from occurring by the effect of thermal expansion in an internal combustion engine and suppressing an increase in size and weight, and collars.

Accordingly, even if a large difference in thermal expansion is produced between a cam carrier 150 of an aluminum alloy material and a control shaft 132 of a ferrous material, the position relation between the intervening drive mechanisms 120 shows the same variation as that of the control shaft 132, and the drive mechanisms can be adjusted to a same lift amount for the intake valves of cylinders. Also, the intervening drive mechanisms 120 can be supported on the collars from both sides.
