Automotive industry legislation

Exhaust emission legislation has become more and more stringent over the last years, demanding for lower engine raw emissions and more efficient exhaust converters. Simultaneous low emission limits for different species, e.g. PM and NOx, lead to the development of combined aftertreatment systems, consisting of different catalyst technologies and particulate filter. Simulation can make a considerable contribution to shorten the time and lower the cost of the system development. In this publication, the current status of exhaust aftertreatment simulation tools used in automotive industry is reviewed. The developed models for DOC with HC adsorption, NSRC and catalyst for SCR of NOx by NH3 (urea) were included into the common simulation environment ExACT, which enables simulation of complete combined exhaust aftertreatment systems. 

AB Konstruktions-Bakelit (KB) is a medium-sized company with 400-500 employees. It is mainly involved in business-to-business activities with the automotive industry as the main client. This keeps the company away from direct exposure to public environmental pressure. For KB, the main driving forces for improving environmental performance are the environmental pressure transmitted from OEMs to sub-suppliers and the legislative pressure that effects all industry. For this reason there is no specific environmental activity within the company, more than that reflected in the satisfaction of... 

With increasing emphasis being placed by various governmental bodies on the use of flame retardant materials in the building, textile and automotive industries, the subject of flame retardance is assuming increasing importance in the plastics industry. Much legislation already exists more may be expected to follow. 

Automotive Catalytic Converter Catalysts. California environmental legislation in the early 1960s stimulated the development of automobile engines with reduced emissions by the mid-1960s, led to enactment of the Federal Clean Air Act of 1970, and resulted in a new industry, the design and manufacture of the automotive catalytic converter (50). Between 1974 and 1989, exhaust hydrocarbons were reduced by 87% and nitrogen oxides by 24%.
