Tailoring Fuels for the New Millennium

This introductory paper presents the perspective of an oil company on automotive fuels development and vehicle emissions. Studies are described of fuel effects on aftertreatment catalyst efficiencies for both modern gasoline and diesel vehicles. Shell has consistently responded to the fuel requirements of both customers and new vehicle technologies over the past few decades and will continue to do so. As society moves to more sustainable energy sources, the future of automotive mobility is discussed; new, alternative vehicles technologies are expected to emerge, which may require completely new fuels, and this could lead to a reshaping of our fuels (energy) business.
