Flash-boiling of fuel sprays occurs when a super-heated fuel is discharged into an environment whose pressure is lower than the saturation pressure of the fuel and can dramatically alter spray formation due to complex two-phase flow effects and rapid droplet vaporization. In gasoline direct injection (GDI) engines, typically, it occurs during the i...

The ever more stringent vehicle emissions rules are leading gasoline engine research and development toward the use of direct injection systems. This technology is already present in commercial vehicles, but there are still many aspects that can be improved and need a deeper investigation. For this reason, it was considered important to provide a r...

The road transport sector is the main cause of air pollution, especially in highly urbanized areas. The road mobility is an aspect of quality of life which is difficult to give up: the inelasticity between price and fuel consumption calls for measures stronger than those expressed by the market supply-demand relations, directing attention toward th...
