There is no longer any doubt that internal combustion engines are on the way out the door. Most of us now believe that the doom of the ICE will be the electric cars, with their motors and batteries.

Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as ...

A single atom inside of a reflective cavity could be enough to drive a piston in a tiny, quantum version of an engine. The essential feature of any engine is that it converts heat into work, which can ...

An engine with no crankshaft, where the pistons float on air? It’s not a dream; it’s a free piston engine and it might be the next major advance in car tech. When we think of automotive technology of ...

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 ...

Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both into a single ...

Monolith Engines has developed a set of dual (Fig. 1) and quad (Fig. 2) opposed piston engines (watch Two and Four Cylinder Single Stroke Opposed Piston Engines on Engineering TV). The engines uses a ...

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