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 ...

Direct injection. Just about every car has it now, and those that don’t probably will in the next few years. It can add power, reduce emissions, and is a big part of why just about everybody is ...

Port fuel injection (PFI) was a major milestone in the early '80s. The integration of PFI rapidly changed the way fuel was delivered by increasing fuel economy and improving engine performance. Even ...

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 ...

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 ...

Despite advancements in hybrid power-trains and electrification technology, gasoline engines remain the predominant choice in passenger cars because of continued efficiency improvements, most recently ...

As we entered into 2014, the industry was abuzz with the acronym “GDI,” otherwise known as Gasoline Direct Injection. The “gasoline” distinction is significant because direct injection has existed in ...

Direct-injection engines were introduced with a promise that sounded ideal: more power, better fuel efficiency, and cleaner ...

GM Powertrain announced today it will deliver a 3.6-liter V-6 gasoline engine with direct injection and variable valve timing (VVT) technologies in the 2008 model year. A vehicle application will be ...

Until the early 1990s, many gasoline engine designs relied on carburetors to produce the fuel-air mixture needed to make the power that makes a car move. However, as the regulations around fuel ...

Every new car sold in the United States today uses fuel injection, but not all fuel injection systems are the same. Some cars use port injection, while others use direct injection. Some even use both.
