There's a new acronym floating around the performance industry—GDI—and it stands for gasoline direct injection. Among domestic production engines that have jumped heavily into the GDI segment are the ...

The Dornier Do-335 used a push-pull engine arrangement to reduce drag and eliminate asymmetric thrust. Flight testing showed ...

Pistons play the ultimate role in an engine, but despite that, it's still hard to fully wrap your head around all the forces involved. There are plenty of moving parts in an internal combustion engine ...

We all know how a conventional internal combustion engine works, with a piston and a crankshaft. But that’s by no means the only way to make an engine, and one of the slightly more unusual ...

Today, on the menu, we have something very interesting. A genetically engineered offspring of pistons and rotaries, a completely novel creation whose anatomy allegedly inherits only the best genes ...

Free-piston engine generators and linear machines represent an innovative departure from conventional rotary systems, offering high thermal efficiency and operational flexibility by eliminating the ...

Gasoline and diesel engines feature many differences aside from fuel type. Compared to gasoline engines, a diesel is typically a lower-revving, torquier design, hence why it's often preferred over ...

While the world is trying to go EV, heavy duty diesel trucks like the Ford F-250 are still the rage for those who do big jobs (or want to look like they do). Many truck owners are always on the ...

While there have been many unusual engine designs over the years, there haven't been many advancements involving the inner workings of the piston engine, except for higher-quality components, since ...
