The interaction of fuel economy and emission control in Europe – a literature study

Various proposals for more stringent emission legislation have been made for the medium term future in Europe. Set against these proposals is the intensified search for improved vehicle fuel economy and the probable result that overly stringent emission control would decrease fuel economy.

The paper will discuss interaction of fuel economy and emission control in Europe based on a survey of the literature. The performance and operating cost of a number of alternative control strategies and engines will be compared using a current conventional gasoline engine as a basis.
