The power, fuel efficiency, and longevity of an engine will heavily depend on the fuel that’s being delivered. Furthermore, an engine’s efficiency is dependent on a precisely calculated air-to-fuel ...

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 ...

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 ...

Automakers have long touted the benefits of fuel injection, claiming increased efficiency and power. But as more cars have the system installed (around 73% in 2023), more and more consumers are ...

Times are a-changin’, folks. 2010 was twelve years ago, and a lot of the affordable used performance cars available today are more technologically advanced than ever. And none of those technologies ...

We'll discuss the tuning flexibility of port injection, the advantages of the cooling effects of in-cylinder direct injection, as well as how dual injectors (both port & direct) can offer the benefits ...

Direct injection has been considered the most effective approach to overcome the inherent short-circuiting of fuel in a two-stroke engine. A practical application of this technology on an 1100cc ...
