Some cars use port injection, while others use direct injection. Some even use both. What's the advantage of that? Jason Fenske of Engineering Explained breaks it down in the accompanying video.

The answer is bringing fuel to the fire by two separate paths, and a few makers already are fitting their engines with both port and direct injection. Toyota introduced this technology ...

How Gasoline Direct Injection causes Chain Wear, Fuel Dilution, and LSPI. Oil formulations and testing can ensure direct ...

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 ...

Toyota has offered its D-4S fuel injection system for a number of years with certain models of its 3.5-liter V-6 engine. The D-4S uses a combination of both direct and port injection to blend the ...

In a port injection engine, the fuel would clean the fuel injectors and parts of the engine in which it was sprayed. However, in a direct injection system, the fuel addition is so precise that it ...

Direct injection motors are the new cool kids ... The host also touches on older port-injection motors as well as motors that utilize both methods of fuel-injection. Using diagrams from Bosch ...

As we entered into 2014, the industry was abuzz with the acronym “GDI,” otherwise known as Gasoline Direct Injection. The “gasoline” distinction is significant because direct injection has ...

The power, fuel efficiency, and longevity of an engine will heavily depend on the fuel that’s being delivered. Furthermore, an engine’s efficiency is dependent on a precisely calculated air-to ...

Traditional fuel-injected engines that don't use direct injection usually use throttle body injection or port injection; those systems spray gasoline into the intake port where it's mixed with air ...

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 ...
