Optimization of Exhaust Systems
SAE Technical Paper Series, 2002<div class="htmlview paragraph">Some design optimization studies of automotive exhaust systems are carried out using numerical simulation. The numerical simulation involves computational fluid dynamics (CFD) for fluid flow and temperature distribution and finite element analysis (FEA) for subsequent structural analysis.

The intake system of an engine includes an air cleaner for removing dust and dirt from the incoming air and an intake manifold. Depending upon the engine, the incoming air may also pass through a carburetor or throttle-body fuel injector and/or through a turbocharger compressor.

Stability of Mechanical Exhaust Systems
Indoor Air, 1999The mechanical exhaust system, where outdoor air is supplied through infiltration and devices in the building shell, is a common ventilation technique in multi-family buildings in Europe. The objective of this paper is to determine how well the system meets indoor air quality standards and regulations and how sensitive it is to disturbances, such as ...

<div class="htmlview paragraph">More and more automobile manufacturers are requiring a typical sound pattern for a car or a platform, even the unique „brand sound” for a whole brand, on the top of their specification. By this image factor sound design becomes increasingly important for the exhaust system development.

The function of air cleaners is to hinder dust contained in the intake air from entering the engine and thus to prevent premature engine wear. Air cleaners are additionally employed to damp intake noise.

<div class="htmlview paragraph">When designing an exhaust suspension with a flexible exhaust decoupler, the design engineer may want to use the device to decouple motion of the powertrain from the exhaust system. Today, durability schedules and the limits of existing metallic components keep current market flexible decouplers' stiffnesses high. A

Automotive exhaust gas sensing systems
IEEE Transactions on Instrumentation and Measurement, 2001Gas sensors have become an integral component of control systems for internal combustion engines to provide information for feedback control of air-to-fuel ratio (A/F) to achieve improved vehicle performance and fuel economy as well as decreased levels of emission.

Polling systems with a gated/exhaustive discipline
Proceedings of the 3rd International Conference on Performance Evaluation Methodologies and Tools, 2008We consider a polling system where the server cyclically serves the queues according to the following discipline: the server does one round of visits to the queues applying the gated service discipline at each of the queues, followed by one round of visits applying the exhaustive service discipline at each of the queues, and this alternating pattern ...

Exhausted subjects, exhausted systems.
Acta physiologica Scandinavica. Supplementum, 1998A state of 'vital exhaustion', characterized by unusual tiredness, increased irritability and feelings of demoralization has been found to preceed the onset of myocardial infarction and to increase the risk of a new coronary event after angioplasty. Probably this state reflects a decreased activity of the hypothalamic-pituitary-adrenal axis as part of ...
