Diagnostic system requirements

Technical Support Document Revisions to the Malfunction and Diagnostic System Requirements Applicable to 1994 and later New California Passanger Cars, Eight-Duty Trucks, andMedium Duty Vehicles with Feedback Fuel Control Systems (OBD-II), California Air Resources Board, Sacramento, Sept. 14,1989. 

The clear lesson from nature is that effective management of microbial fouling in complex dynamic systems requires a consistently administered program comprised of diagnostics, monitors, environmentally sensible remedies, and careful regulation of those remedies. 

A different but very important area of chemical engineering in the life sciences involves the design and manufacture of health care systems for diagnostic or therapeutic purposes. Consider the example of controlled release drugs or dermal penetration drugs. Here the emphasis is on the system rather than on the compound. The design of these systems requires an understanding of reactions, kinetics, fluid mechanics, and membrane systems. 

AECC supports the implementation of improved Inspection and Maintenance programmes for Europe and the requirement that On Board Diagnostic Systems be installed to monitor the operation of the engine management and emissions control components, including the conversion efficiency of the catalytic converter. This is important as the performance and dmability of the catalytic converter are very dependant on the systems of which it is a key part.
