Turns out the old technology did a few things no computer has matched.

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 ...

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 ...

The first thing you should understand is that direct-port, constant-flow fuel-injection—Hilborns, En-derles, Crowers, whatever—were never designed, nor intended, to be run on the street. All of these ...

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 ...

Modern trucks rely heavily on precise fuel delivery systems to maintain performance, fuel economy, and emissions control.

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 ...

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, ...

The study reveals the mechanisms behind wall film formation, a key contributor to particulate matter emissions under cold fuel conditions The growing concerns about air pollution and its harmful ...

Vehicle fuel injectors are integral to a car's engine fuel delivery system. Fuel injectors are responsible for delivering the right fuel at the right time. Gasoline and diesel-powered engines of all ...
