Description
Technical field
The present invention relates to a kind of internal-combustion reciprocating-pisto, large-scale diesel engine particularly, it has at least one exhaust-gas turbocharger, and the outlet of the pressurized air of exhaust-gas turbocharger links to each other with the charger-air cooler of a postposition by a connecting tube and is assigned the device of the absorbing silencer form that is used to reduce audio emission.
Background technique
Produce pulsation by the compressor of turbosupercharger and in the pressurized air conduit, transmit for the internal-combustion reciprocating-pisto of supercharging.Consequent noise strengthens by the charger-air cooler housing, and housing becomes sounding board.
People begin for a long time to test by the soundproof measures to element that harm is arranged especially and reduce the noise emission that produces in the turbosupercharger.To this, if can apply sound insulation on the whole catheter length or on whole surface of shell, the sound insulation of conduit or housing could produce useful results.Yet this is usually because reasons in structure and infeasible.Sound insulation comprises thicker puigging, and the puigging material is covered by sheet material.This needs very big structure space, and this does not normally have.Applying soundproof measures in addition needs higher expending, close because harm conduit etc. are difficult to usually.Another special shortcoming is: be easy under the high temperature that the puigging material occurs in the zone of its exhaust-gas turbocharger decompose, make that deadening reduces behind certain hour.
Owing to this reason proposes a solution at DE 198 18 873 C2, wherein the diversion member of at least one exhaust-gas turbocharger is provided with at least one silencing apparatus based on the Helmholtz resonator principle, this silencing apparatus comprises the cavity that at least one is separated by the perforated metal plate of corresponding circulation road, the geometric parameter in the hole of perforated metal plate and the wave length of sound of expection are suitable, and the hole component in zone is about 0.5%-1.5%.
Though according to the silencing apparatus compact structure of Helmholtz's principle work but can absorb a large amount of acoustic energy.In fact fluid mass by being arranged in the hole is produced so-called elasticity, quality, vibration system by the wavelength excited vibrational in the zone in each hole in the perforated metal plate, the fluid volume in its hollow cavity is as elastic device.Because with the strong strong damping of friction-produced of hole wall, on the hole wall in zone the hole component with respect to the perforated metal plate be 0.5%-1.5%.Need little space because silencing apparatus reaches on the direction perpendicular to weld tabs diametrically, so advantageously realized a kind of silencing apparatus arrangement, it not only can be arranged in zones such as peripheral conduit and housing, and can directly install in exhaust-gas turbocharger.
Equally for example by DE 35 31 353 C2 known be integrated in absorbing silencer between turbosupercharger and the charger-air cooler.Be provided with the air inlet sleeve pipe that is used for charger-air cooler is connected to pressurized machine at this, on the air inlet sleeve pipe, absorbing silencer is housed, and absorbing silencer comprises sound absorbing element and a cylindrical interior pipe by tough elasticity (z helastisch) material formation with holes that a tubulose is made of elasticity, porous material.
The foamed material proof of porous is fit to do the absorber element material.The glassy glass fibre that also can use mineral material for this reason or have a silicate composition connects.
This material is porous very, has shortcoming thus, the porous material because the high flow velocity degree of pressurized air can come off, and the material that comes off can deposit on the meticulous cooling fin of charger-air cooler.Need dismantle charger-air cooler for essential cleaning course, cleaning course carries out in acid bath bothersomely, and this is again bothersome and very undesirable.
Summary of the invention
Task of the present invention thus is, improve the structure of the described type of beginning with the means of simple economy, keep simple, the compact mode of execution of noise countermeasure on the one hand, and needn't use solution with resonance exhaust silencer, reach high damping effect and long lifetime on the other hand, and needn't stand particularly coming off of porous material of above-mentioned shortcoming.
This task is finished by the feature of claim 1.
By in a diversion member of exhaust-gas turbocharger, being integrated with absorbing silencer at least; be provided with an inner tubal wall that defines corresponding circulation road, constitutes by Drop-proof protective layer penetrating on the acoustics; this tube wall is roughly surrounded with one heart by an outer tube that radially separates; thereby form at least one toroidal cavity; cavity is by (being made by poly-(poly P phenylene diamine terephthalamide) by aramide-fibre; being also referred to as Kev draws; the trade (brand) name of Du Pont ground) absorbent material that constitutes is filled, and has guaranteed that favorable noise absorbs on more than or equal to the upper frequency scope of 1kHz.
Aramide-fibre has roughly intensity (the density 1.44g/cm identical with glass fibre
3, the about 2800N/mm of tensile strength
2), but suitable flexible.Aramide-fibre can extend before inefficacy widely.Aramide-fibre is an aromatic polyamide base organic chemistry fiber.
This absorbing silencer raw material has high anti-mechanical material deciduous (for example, being caused by high flowing velocity).Produce the superfine little dust granules that for example can remove easily by industrial dust collector by wearing and tearing.Do not need special purpose machinery or undesirable cleaning by acid bath.
This fiber is very insensitive and nonflammable to chemicals in addition, and has heat-resisting quantity (just carbonization and thermolysis more than 300 ℃), and the sound insulation raw material can not melt and sintering thus, because the temperature of exhaust-gas turbocharger pipe is no more than 250 ℃ usually.
Aramide-fibre stable (so the life-span is long) reaches not biodegradable in addition.If the condensed water this point is very favorable.
