Just because LEGO Technic is technically a toy doesn’t mean that you cannot do solid engineering with it, like building ...

We've highlighted the guys at Garage 54 a few times for some of their craziest builds and bizarre engineering experiments. With all due respect to the American tuners and hot-rodders squeezing extra ...

The story of how Honda developed an oval-piston race engine that ultimately failed but still made history along the way.

Positive Crankcase Ventilation—three dirty words, but do they really need to be perceived that way? In general, the PCV system has two main functions: vapor relief and liquid separation. PCV systems ...

Over on his YouTube channel [Tom Stanton] shows us how to build a Stirling Engine for a bike. A Stirling Engine is a heat engine, powered by the expansion and contraction of a working fluid (such as ...

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 ...

When we here in the modern age think of an “engine,” we are usually thinking of a four-stroke, four-cylinder, gasoline-fed, internal-combustion engine with the valves on the top. But why must that be ...

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 ...

Have you ever imagined a bike powered not by gasoline or electricity, but by the simple act of heating and cooling air? It might sound like something out of a science fiction novel, but the concept is ...
