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 ...

The mind-bending world of birotary engines - a hybrid of piston and rotary technology that could revolutionize aviation. But ...

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 ...

Dimpled pistons might sound strange, but some say they could be the future for diesel power. We've looked at the arguments ...

A new kind of internal-combustion range extender for electric vehicles skips crankshafts and camshafts entirely, with packaging that could more easily coexist with battery packs. The UK firm Libertine ...

Toyota is hot on hydrogen fuel cells for its next-generation cars, but it’s not going cold on internal combustion just yet. The company’s R&D division has developed a Free Piston Engine Linear ...

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 ...

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 ...

Piston-engined fighters ruled the roost for thirty years. A brutal survival of the fittest ensured a rapid evolution of these characterful machines; the final fighters were over six times faster and ...

One of the many challenges facing engine designers is the need to increase power output while simultaneously retaining or improving efficiency. Although a four-cylinder engine is still an engineering ...

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