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 ...

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 ...

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 ...

Flexibility in respect of fuel types, compact dimensions and high efficiency combined with low emissions – these properties characterise the free-piston linear generator (FKLG), the brainchild of ...

In an advance toward introduction of an amazing new kind of internal combustion engine, researchers in China are reporting development and use of a new and more accurate computer model to assess ...

A new engine type entering production for kitplanes could find its way into production aircraft. The Dyna-Cam is a cam-drive free-piston engine which is more compact, lighter and smoother, and ...

Antony Ingram April 30, 2014 Comment Now! The concept of range-extended vehicles--electric cars with a gasoline generator to extend their range--is an intriguing way of combining the benefits of both ...

Stirling engines are really cool machines, invented by Reverend Dr. Robert Stirling in 1816 to rival the steam engine, they are one of the most efficient engines ever conceived. Building one is a very ...

History makes fools of us all sometimes, none more so than when we dismiss certain ideas out of hand, only for them to come back years later and eat our words. That's why we're always intrigued by ...

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.
