Sandia National Laboratories researchers (left to right: Nathan Harry, Christopher Nilsen, Drummond Biles, and Charles Mueller) show off their prototype of ducted fuel injection module for diesel ...

Direct-injected engines helped modern vehicles produce better fuel economy and stronger performance, but mechanics are ...

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 ...

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 ...

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 ...

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 ...

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 ...

While carbon buildup happens on essentially all engines, gasoline, diesel, N/A, or boosted, it's an increased concern in GDI engines. Standard Electronic Fuel Injection features injectors higher in ...

The “old-school” car habits that can instantly double your gas mileage High-tech modern vehicles equipped with advanced fuel ...
