What is gasoline direct injection and how is it different from traditional methods of getting fuel into your car's engine? You may have read or heard one of your favorite Car Tech editors talking ...

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 ...

From the 1954 Mercedes-Benz 300 SL to modern GDI, explore how fuel injection rose to dominance and why carburetors never ...

If you ask any modern automotive nerd to name the first vehicle to feature a direct-injection diesel technology, you will likely get one of two answers. The Volkswagen Audi Group loyalist will point ...

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Despite very different applications, the L78 and LS6 V8 engines share a number of mechanical and technological similarities, including fuel injection hardware.

Gasoline direct injection, or GDI, is one of the most crucial bits of technology in the modern internal combustion engine. In engines equipped with GDI, highly pressurized gasoline is sprayed directly ...

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 ...

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 ...

Direct injection engines deliver fuel at high pressure directly into the combustion chamber. When the fuel spray strikes surfaces such as the piston crown or liner, a thin liquid film forms. This film ...
