This book chronicles a 35-year success story the technology that was developed and the progress that was made to achieve the goal of reducing air pollution from automobiles. Allowable air pollution from passenger cars has been lowered steadily to levels less than 5 per cent of those for pre-control era vehicles, writes author J. Robert Mondt, who spent over 30 years working on the development of emission control systems for automobiles. Mondt covers both the technological and political aspects of this effort, from the early environmental concerns in California to the Clean Air Act of the 1960s to the introduction of catalytic converters in 1975.
