Abstract: A noise reduction structure of an alternator of a vehicle is provided to reduce the total noise of an engine by reducing largely wind noise generated at a high-speed range as well as electromagnetic noise generated at a low-speed range. A plurality of ribs(113a) are projected from one side of a flange part of a front housing(110) opposite to a rear housing(130). A front end of each of the ribs(113a) comes in contact with a front side of the rear housing(130) when the front housing(110) and the rear housing(130) are assembled with each other. A sealing member(170) is used for filling a hollow formed between wings of a rotor(15). A thickness of a rim formed at the front housing(110) has a ratio more than 1.6 percent to a minimum for a total diameter of the front housing(110). Four ventilation holes and three ventilation holes are formed in a constant interval to opposite diagonal directions between the ribs which are intersected on the front side of the front housing(110).

Abstract: PURPOSE: A noise reducing structure for a timing chain is provided to expand a supporting portion between a guide and a chain and to reduce noise by constraining flow between a guide and a bolt. CONSTITUTION: A noise reducing structure for a timing chain has a crown shape portion(C). The timing chain transfers power of an engine by a sprocket connecting to a crank shaft. A fixing hole is formed to fix a guide(10) to a cylinder block portion by a bolt(10'). The guide minimizes noise and vibration. A supporting portion(L) is formed to support a specific section along the chain. A washer(10") is intervened to prevent flowing by difference of diameters(D,d) with the bolt. The crown shape portion is protruded to both sides of the supporting portion. Thereby, an extended supporting portion(L') is formed. Therefore, noise of transferring power of the chain is prevented by extending the supporting portion.

Abstract: PURPOSE: Fuel pipe structure for reducing noise is provided to reduce noise, and to prevent breakage of a fuel pipe by decreasing pressure of fuel injected to an outlet of a fuel injection pump, and by offsetting frequency with a resonator. CONSTITUTION: An orifice(11) is installed in an end of a fuel pipe(10), and the fuel pipe is connected to an outlet(110) of a fuel injection pump(100). High pressure of fuel injected through the outlet of the fuel injection pump is decreased with passing fuel through the orifice, and endurance is improved with reducing noise and breakage against fuel pressure. The diameter of the fuel pipe is formed to be 3 mm, and the bore of the orifice is formed to be 0.5 mm. The frequency is reduced in decreasing fuel pressure with installing a resonator(12) in the fuel pipe. Breakage of the fuel pipe is prevented with lowering the fuel pressure by forming the orifice, and the frequency in decreasing fuel pressure is offset by the resonator. Noise is reduced, and the endurance of the fuel pipe is improved.
