Engine mounts fluid

Fluid engine mounts (Figure 2.1) for the aerospace industry and automotive hydromounts require the bonded rubber to act as both a seal for the fluid and as a spring component... 

Actual ER damping devices have been designed for meeting practical needs such as shock absorbers [16], full-car suspension system [17,18], automotive engine mounts [1], bearing damping with an ER fluid [19], etc. A concentric cylinder shock absorber using the Bayer Rheobay 3565 ER...

Most butyl rubber is used in the tire industry. Isobutylene-based rubbers are used in underhood hose for the polymer s low permeability and temperature resistance, and high damping, resihent butyl rubbers are used for noise and vibration attenuation applications such as automotive mounts for the engine and vehicle. Chloro- and brominated butyl rubber formulations are used in automotive hose applications where contact with fuel or air conditioning fluids occurs.

Dip pipes and other probes must be supported—usually by attaching to waU-mounted baffles—or stiff enough to withstand the bending moments imposed by the fluid forces. Discuss with yom local mechanical engineer. 

Wire insulated with FIFE is used for connections to oxygen sensors mounted in vehicle exhaust manifolds. In this hot environment, FIFE provides reliable dielectric protection for wiring that is vital to control of exhaust emissions. ETFE is used to insulate wiring for other high-temperature locations near engines, and wiring exposed to hot hydraulic fluid within automatic transmissions. 

The approximate numbers given for these quantities represent good current practice. It may be possible to do better by extreme care. On the other hand, in most engineering measurements a lower order of accuracy is permissible, and this may allow relaxation of certain requirements such as strain-free mounting of resistors, homogeneity of thermocouple materials, purity of vapor pressure fluid, sensitivity, and accuracy of associated instruments, etc.
