Automotive systems

The generation of au pollutants, ineluding VOC s, from automotive vehieles was identified to eome from two prineipal sourees vehiele exhaust emissions, and fuel system evaporative emissions [4], Evaporative emissions are defmed as the automotive fuel vapors generated and released from the vehiele s fuel system due to the interactions of the speeific fuel in use, the fuel system characteristics, and environmental factors. The sources of the evaporative emissions are discussed below and, as presented m the remainder of this chapter, control of these evaporative emissions are the focus of the application of activated carbon technology in automotive systems.

The stability of electrocatalysts for PEMFCs is increasingly a key topic as commercial applications become nearer. The DoE has set challenging near-term durability targets for fuel cell technology (automotive 5,000 h by 2010 stationary 40,000 h by 2011) and has detailed the contribution of the (cathode) catalyst to these. In particular, for automotive systems as well as steady-state stability, activity after simulated drive cycles and start-stop transients has been considered. In practice, both these treatments have been found to lead to severe degradation of the standard state-of-the-art Pt/C catalyst, as detailed next.

For many potential applications a fuel cell system must be capable of surviving and operating in extreme conditions. Presence of water in the membrane and fuel cell requires special attention to fuel cell stack and system design to allow system survival and start-up in extremely cold conditions. Most automotive systems have already demonstrated this capability.

A sanding sealer is designed for easy sanding after short dry so that smoother top coats can be attained. Sanding sealers are most important in furniture finishes and industrial finishes such as automotive systems. 

Thus, as an elastomer is compressed in, say, the Z-direction (as in an isolator on a rubber grommet, engine mount, or transmission mount), the mount will deform in the X and Y directions. This value is nearly 0.5 for natural rubbers (typically used for mounts in automotive systems). For steel, Poisson ratios are around 0.3. The Poisson ratio has no units.

The above sensors enabled the automotive industry to implement the very demanding systems of today s vehicles. Many more innovative automotive systems are being developed, and sensors will contribute significantly to the development and performance of these systems in the future. 

Presently, automotive sensors are mostly dedicated solely to a particular system. Future sensors will have to be designed as multiple-use sensors for incorporation into different automotive systems. Each sensor then either has to include a bus controller or will be combined - where possible - with other sensors into an intelligent sensor-subsystem that performs a certain level of information preprocessing, for example, an inertial sensor cluster that delivers vehicle dynamics data to the bus. Particularly in the field of inertial sensors will such sensor subsystems emerge in the future - this trend is already being seen in the emergence of multi-axis inertial sensors. 

Error storage technology is well known for automotive systems. For example, sensor failures, battery failures, and failures of the charger are detected and stored. Normally, these errors are displayed (e.g., via a red warning light) and, in some instances, may signal a requirement for maintenance. 

The architecture of the 12-V automotive system is shown in Fig. 11.7. Within the battery system architecture fundamentally little has changed for many decades, with the possible exception that thermal management has become less straightforward and now requires additional components such as heat shields or boxes to help thermally isolate the battery from the engine.
