Port fuel injection and direct injection are similar but distinct systems, so why do some engine designs include 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 ...

Modern engines are cleaner and more efficient than the ones you grew up with, yet many drivers are discovering a new headache ...

SAE International Journal of Engines, Vol. 13, No. 1 (2020), pp. 77-92 (16 pages) At gasoline direct injection, light-duty engines operated with homogeneous, stoichiometric combustion mode, ...

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 ...

A Kia driver stopped into an unconventional place to get an oil change—an Advance Auto Parts—and that kicked off a conversation about a certain kind of engine and the love that it might require. The ...

The fuel injection pressures used in gasoline direct injection (GDI) engines have increased in recent years to improve fuel efficiency and reduce emissions. Current GDI engines use injection pressures ...

Fuel injector cleaner serves an important function in vehicle maintenance. Most vehicles sold today have fuel injectors. Those injectors work by delivering precise amounts of gasoline or diesel fuel ...

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.
