This text highlights the on-going need for emission reduction strategies and technologies in transport and off-highway (non-road) mobile machinery.

This volume provides the reader with the opportunity to read exports that discuss: ongoing challenges; possible solution and their competitive nature; latest achievements, and the visions that they were based on. "21st Century Emissions Technology" is useful reading for all those working in industry groups involved in combustion systems, fuels, fuel and air systems, engine design options, engine control, after-treatment, vehicle and machine systems, emission measurement techniques, and legislation trends.
