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 ...

It has been touted as the automotive holy grail, the ultimate marriage of better performance and greater fuel economy. It’s the direct-injection (DI) engine, the latest technology designed to squeeze ...

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 ...

Half of the U.S. new-car and truck fleet now is equipped with gasoline direct injection (also known as GDI)—which means the fuel is sprayed straight into the combustion chamber. This begs the question ...

Direct-injection engines are pretty common in new cars these days, but how exactly do they work? Well, this explainer video put together by the YouTubers at SavageGeese gives us an in-depth look at ...

So, since we're apparently on the summer session of weird crap: HHO injection for engines. The general approach involves splitting water into hydrogen and oxygen (hence HHO, because... well, I don't ...
