Abstract Nowadays, downsizing and turbochargers are more frequently used, mostly for petrol engines. It can lead to an increase of NVH issues related to the turbos, such as the hiss noise propagation in the air ducts. Hutchinson, among all its activities, supplies rubber and plastic parts for the car industry, especially in fluid management systems. The turbocharger’s airborne noise issue has now been tackled for ten years by implementing acoustic devices in the line and providing solutions to car manufacturers with our hot-side rubber ducts. In this paper, will be first presented the main HP air loop NVH issues, and then explained an approach to design technical solutions. Generally speaking, the noise propagates inside the hot side air hoses, crosses the weakest parts of the system by acoustic emissivity to reach finally the driver and passengers’ ears.

AMS3248D
This specification covers an ethylene propylene (EPM) rubber in the form of sheet, strip, tubing, molded shapes, and extrusions. Primarily for parts, such as gaskets, grommets, and seals requiring resistance to phosphate esters and/or to ozone. Not suitable for use in contact with petroleum base fluids due to excessive swell.

AMS3260D
This specification covers an ethylene propylene (EPDM) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes. This products has been used typically for parts, such as door seals, low-pressure gaskets, dust covers, and shock absorption devices, requiring resistance to weathering, phosphate ester base hydraulic fluids, and polar solvents such as steam, water, and ketones, but usage is not limited to such applications. This material has fair resistance to all materials listed. Where better resistance to a particular fluid is required, use an AMS for the material compounded specifically for good resistance to that fluid.

AMS3237G
This specification covers a butyl (IIR) rubber in the form of sheet, strip, extrusions, and molded shapes.

These products have been used typically for parts, such as diaphragms, gaskets, grommets, and seals, requiring resistance to phosphate esters or low permeability to gases, but usage is not limited to such applications. The material is not suitable for use in contact with petroleum-base fluids due to excessive swell. Each application should be considered individually.

AMS3357H
This specification covers a silicone (VMQ) rubber in the form of sheet, strip, tubing, extrusions and molded shapes. Primarily for parts required to operate or seal from -55 to +230 degrees C (-67 to +446 degrees F), compounded especially for aircraft piston engine oil resistance and low compression set. Silicone elastomer is resistant to deterioration by weathering and by high-aniline-point petroleum-base oils and remains flexible over the temperature range noted. This material is not normally suitable for use in contact with gasoline or aromatic fuels and low-aniline-point petroleum-base fluids due to excessive swelling of the elastomer.

Software's role continues to expand Design teams use different technologies to create new software and link systems together. Emissions regulations and engine complexity With the European Commission announcing a Stage V criteria emissions regulation for off-highway, scheduled to phase-in as earlly as 2019, there will be an end to a brief era of harmonized new-vehicle regulations. Will this affect an already complex engine development process? Evaluating thermal design of construction vehicles CFD simulation is used to evaluate two critical areas that address challenging thermal issues: electronic control units and hot air recirculation.
