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 ...

If you think direct-injection diesel engines made their debut in the 1980's, think again. The first diesel without extra plumbing debuted decades earlier.

Port fuel injection has some big advantages, but automakers increasingly are using gasoline direct injection instead. The reasons are numerous.

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 ...

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 ...

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.

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 ...

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 ...

There was a time, not long ago, when most of the world didn't really see a path forward for internal combustion engines. Yet, something happened along the way, and the technology that has been ...

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.

A cutaway image of a direct-injected BMW engine - Ton1~commonswiki/Wikimedia Commons Until the early 1990s, many gasoline engine designs relied on carburetors to produce the fuel-air mixture needed to ...
