Direct-injection engines were introduced with a promise that sounded ideal: more power, better fuel efficiency, and cleaner emissions, all from a more precise way of delivering fuel. On paper, the ...

Fuel delivery depends on more than what happens at the injector. For fleet, maintenance and technical professionals, looking at the full path from pump to injector can provide useful context ...

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 ...

In the past, race-type constant flow fuel injection (Fl) systems have met with little success on the street. Usually designed only for high-speed idle and wide-open throttle (WOT) operation, such ...

While carbon buildup happens on essentially all engines, gasoline, diesel, N/A, or boosted, it's an increased concern in GDI engines. Standard Electronic Fuel Injection features injectors higher in ...

We often talk about the benefits of fuel injection on off-road vehicles. Generally, these systems run more reliably than carbureted systems, but they are, at the end of the day, a bit more complex ...

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.
