Most modern vehicles have multi-port fuel injection (MFI) with a separate fuel injector for each cylinder. This system mixes the fuel and air together right in the intake port for eachengine cylinder ...

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

Just about every new vehicle is fuel-injected. (The last carbureted vehicles came off the assembly line in 1990.) Although they’re more expensive to service than carburetors were, fuel injection ...

An experimental study of spray structures from a regular dual-stream (RDS) injector and an air-shrouding dual-stream (ASDS) injector was carried out extensively to understand the spray characteristics ...

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 ...

Direct fuel injection isn't exactly a new idea. It's actually been around since World War II, when it was used on aircraft engines designed by the Germans and Russians and has been used in diesel ...

If you go to as many cars shows as I do, you happen to notice the trends and modern technology in our classic vehicles. Modern fuel injection in our classic trucks is one of those trends that simply ...

Audi has announced that they will be using their Fuel Straight Injection (FSI) direct gasoline injection system on all future engines. Technology development related to indirect (port) fuel injection ...

If you flip through the list of features on just about any new car or truck, you’re likely to see the words “direct fuel injection,” or DI. The concept is straightforward enough -- engineers have ...
