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 ...

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 ...

Automobile engines have undergone tons of changes over the years, primarily to make them more efficient. For the most part though, engine changes result from a string of iterative improvements on ...

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 ...

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 is exciting technology in that it allows car enthusiasts to have their cake and eat it too. How so? By both improving fuel efficiency and increasing horsepower. This being the case, ...

In a 2023 report, McKinsey & Company projected 35 GW of new power will be needed for data centers in the U.S. by 2030. This forecast doubled the required power consumption from data servers, up from ...

Turbo Fuel Stratified Injection technology for gasoline engines was once a remarkable innovation that has since become quite commonplace. Traditional fuel-injected engines that don't use direct ...

It's an amazing time when there's new technology in the industry as it forces a new rivalry in speed parts, and direct-injection is firmly in the high-performance arena whether anyone likes it or not.

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 ...

Assuming you have gotten past the concept that fuel is now shot directly into the combustion chamber, let’s talk about what happens next. The chamber on a Gen V engine has been designed with over a ...
