The potential of fuel direct injection regarding the performances of a SI engine is
transformable in significant advantages only by an accurate control of the internal air/fuel …

The first part of the paper gives an overview of the results obtained with European GDI-
powered vehicles launched on the market. Thereafter, a discussion of in-vehicle limitations …

The main objective of the paper is to describe the optimization work performed to adjust
direct injection (DI)-technology to SI-engines running at high (8000 to 10000 rpm.) and …

Abstract Gasoline Direct Engines offer many advantages as compared to PFI engines, as
regard efficiency and specific power. To fully exploit this potential a particular attention must …

A methodology that uses simultaneously three dimensional (3D) calculations and advanced
experimental tools has been developed in order to characterize air/fuel mixing and …

In the course of the last few years a continuous increase of the injection pressure level of
gasoline direct injection systems appeared. Today's systems use an injection pressure up to …

In the future generation of low consumption SI-engine layouts, it has become necessary to
reduce costs as well as the complexity level and, increase the system reliability by the latter …

Downsized, turbocharged GDI engines are considered as the most effective system
architecture car makers can implement to meet stricter CO 2 production and pollutant …

Modern injection systems are characterized by low cost, light weight and diversified
components based on a mature technology. In addition, the constant growth of …

The suggestions for upcoming Euro 2000 clean air act puts an increasing legislative
pressure for lower specific fuel consumption in order to reduce the emission of CO2. and …
