Description The vacuum harness for Ford's newly designed 4.6 liter engine, used on 1996 F150 Trucks delivers vacuum from the reservoir where it is generated to several critical operating systems. The harness sits immediately on top of the engine, facing continuous operating temperatures of 300ºF and brief periods above 400ºF. With a federal lifetime requirement of 120,000 miles for emission components, Ford engineers found that standard nylons used for the vacuum tubing could have difficulty meeting the longevity requirements given operating conditions. Ford chose Stanyl® for the vacuum tubing in the harness. The long-term heat aging characteristics of Stanyl® ensure that the tubing does not become brittle and crack, causing potential failure of critical systems such as exhaust gas recirculation (EGR), fuel pressure regulation, vapor management, and others.

Description Car manufacturers VW and Audi are to use the polymer Stanyl®, manufactured by DSM, in the fuel-injection system of their new generation of diesel engines. Their supplier Tyco-Electronics has opted to use the DSM polymer Stanyl in the cabling of the fuel-injection system. Stanyl is a grade of nylon (polyamide 46) developed and patented by DSM that, unlike ordinary nylon, is resistant to high temperatures.
VW and Audi intend to use pump-injector technology in each of the cylinders of the fuel-injection system. This technology produces a higher injection pressure than common-rail systems. The connectors and the couplings in this pump-injector system are made from Stanyl TW200F3 (PA46 GF15) in order to ensure reliable connections between the interior and the exterior of the engine.

With operating temperatures in the engine varying between 120 ºC and 160 ºC, the polymer used has to have extremely good resistance to engine oil, especially to the particularly aggressive bio-diesel mixture. The polymer must also be resistant to brittleness in these conditions and to corrosion caused by these substances.

Thanks to its very high crystallinity Stanyl is particularly resistant to both engine oil and diesel fuel. Its very good flow properties also make Stanyl TW341 (PA46 UF) a sound choice for use in ducting. The integrated hinge has a bearing function under load and must be able to retain its functionality throughout the life of the engine, including after modifications. Stanyl TW341 is capable of meeting these extremely high durability requirements.
