This study investigates the formation of wall films in direct injection engines, a key factor in particulate matter generation. The results show that cold fuel adheres more to the wall creating ...

The fuel injection pressures used in gasoline direct injection (GDI) engines have increased in recent years to improve fuel efficiency and reduce emissions. Current GDI engines use injection pressures ...

Gasoline direct injection (GDI) continues to be a weapon in the technology armoury of automakers in their fight to reduce CO2. Manufacturers believe that homogeneous applications of GDI will be ...

If you flip through the list of features on just about any new car or truck, you’re likely to see the words “direct fuel injection,” or DI. The concept is straightforward enough -- engineers have ...
