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 has quickly become a must-have technology for automakers, who are preparing to meet the 35.5 mpg federal standard for the 2016 model year. In 2010, about 10 percent of light ...

Gasoline direct injection (DI) engines have been lurking in the shadows of gasoline-burning, internal combustion engine development for decades but are now becoming mainstream. This is all good, as DI ...

What it does: The high-pressure system injects fuel directly into each cylinder of the engine to increase power and torque without sacrificing performance or increasing emissions. An advanced engine ...

The basic difference between direct injection (DI) and the port-fuel injection (PFI) systems we've become familiar with since the mid-1980s is that PFI sprays fuel into the intake manifold (behind ...

With both gasoline and diesel engines having their own particular advantages and disadvantages, automotive component manufacturer Delphi is looking for a best-of-both-worlds solution with a ...
