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 ...

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 ...

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 ...

As hot rodders, we tend to worry most about changes that make our pursuit of power harder or more expensive. That's totally justifiable; new technology often brings both complication and a higher ...

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.

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 ...

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 ...

The other day I dropped my car off at a European specialist shop, and while I was there, a technician was working in the engine bay of a Mk7 Golf R, cleaning out carbon deposits off the intake valves.
