The Unstoppable Versus the Immovable-A Personal View of the Future Facing Gasoline Direct Injection in the Face of Euro Iv
Published January 01, 1998 by Institution of Mechanical Engineers in United Kingdom
Euro IV, when compared with the starting point in 1971, will represent close to a 99% reduction in exhaust emissions. Achieving this will require hitherto undreamt of levels of emission control. Substantial reductions in CO2 will also be required in the same timescale.
The industry's response to the need for CO2 reduction has been to develop the gasoline direct injection concept. GDI has the potential to ape the diesel engine by allowing part-load operation without inlet throttling. GDI does however bring problems, among them, like the diesel, the control of smoke and NOx
