European legislation is among the most stringent in the world, and in the future it will form the framework for other markets' goals of reducing emissions. And that stringency is driving innovation within the R&D facilities of OEMs and Tier One suppliers, helping them to meet targets no matter where vehicles are sold, Engineers have met many of the emissions targets by developing complex downsized, turbocharged gasoline engines that use direct injection to distribute and burn fuel more efficiently, But today's 200bar systems will soon be superseded by technologies that use far higher pressures. Firms such as Delphi are developing injection technologies that double pressure levels.
