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 ...

Port fuel injection (PFI) was a major milestone in the early '80s. The integration of PFI rapidly changed the way fuel was delivered by increasing fuel economy and improving engine performance. Even ...

In the past, race-type constant flow fuel injection (Fl) systems have met with little success on the street. Usually designed only for high-speed idle and wide-open throttle (WOT) operation, such ...

If you’re in fleet management or the construction industry, you undoubtedly have machines that run on diesel fuel. In addition to large trucks, more than 75% of all heavy construction equipment uses ...

It's a trend we are seeing a lot more of: Even the most dyed-in-the-wool carburetor guys are ditching their mechanical mixers for electronic fuel injection. One recent convert explained his motivation ...

Your diesel engine injector nozzles are responsible for delivering the proper amount of fuel to each cylinder bore for the load and horsepower demand. Over the course of the life of the engine, the ...

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 ...

We often talk about the benefits of fuel injection on off-road vehicles. Generally, these systems run more reliably than carbureted systems, but they are, at the end of the day, a bit more complex ...

Electronic fuel injection revolutionized the auto industry in the 1980s. It came to replace the carburetor in the task of sending fuel to the engine's cylinders but it does much more: it controls ...

The clearances inside diesel injection system parts are closer than those found in any other technology. The plungers and needle valves in injectors need to fit tightly to ensure precise metering and ...
