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 ...

Mechanical injection systems rely entirely on engine driven components to meter, pressurize, and time fuel delivery. In these engines, a mechanical injection pump is driven by the engine's gear train ...

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 ...

Automakers have long touted the benefits of fuel injection, claiming increased efficiency and power. But as more cars have the system installed (around 73% in 2023), more and more consumers are ...

With so much aftermarket power-adding equipment available, we just couldn't leave well enough alone. It started with wanting to add just enough power to our '01 dualie so the transmission wouldn't ...

Diesel engine emissions, notably nitrogen oxides (NOx) and particulate matter, remain a critical environmental and regulatory challenge worldwide. Advances in fuel injection strategies have become ...

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 ...

Westport Fuel Systems recently unveiled its H 2 HPDI fuel system in a demonstrator truck. Westport’s HPDI fuel system technology enables heavy-duty trucks to operate on bio-methane (renewable natural ...
