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 ...

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 ...

Fuel injection, it’s the wave of the future. Well, at least it was in the late 1970s and early 1980s. This was really the dark ages of fuel delivery in cars and trucks. Carburetors worked pretty well ...

The carbureted car and truck era phased out by the early '90s. Carbs are still in use today on a few motorcycles, lawn mowers, and other power equipment, but electronic fuel injection (EFI) is ...

When electronic fuel injection first appeared on performance cars, it represented a major shift in the comfort zone of many hot rodders. Turning screws, replacing jets, and setting float levels were ...

The late 1980’s is a time remembered for trying new things. General Motors took that adage to the next level with this pet ...

The injector is electronically controlled. It is provided pressurized fuel by the car’s fuel pump and has a high micron filter at the top and small holes at the bottom. The filter ensures that any ...

The carburetor didn't fade away — it was federally regulated out of existence.

High-pressure common rail fuel (HPCR) systems are standard on nearly every diesel engine today, from heavy equipment to over-the-road trucks, light-duty trucks, large generators and more. HPCR fuel ...

While fuel-injector cleaning is often recommended by shops and dealer service centers, it probably isn’t necessary unless it’s correcting a running problem. In many cases, just using a quality ...

Researchers have developed a promising yet surprisingly simple modification to diesel engines that could hold the key to reducing the complexity, maintenance, and size and weight of emission ...
