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 ...

How does fuel injection work? Everything you need to know about fuel injection! Throttle body injection, multipoint port ...

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 ...

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 ...

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 ...

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 ...

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 ...

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, ...
