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

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

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 ...

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 ...

While significant sooty black deposits—and even, occasionally, visible puffs coming from the tailpipe—used to be a sign your gasoline car needed a tune-up, they’re a normal fact of life with many ...

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 ...

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.

While port injection is still the most common form of electronic fuel injection, gasoline direct injection is quickly starting to replace it since it provides better fuel atomization, decreased ...
