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 ...

As we move toward battery and hydrogen cell breakthroughs that could wean us off our addiction to oil, here’s at least one engine design from yesteryear that ought to be examined a bit more. The ...

Technically, the combustion engine in any hybrid vehicle is a range extender, but the term commonly refers to gasoline-fueled generators that are used to charge an electric vehicle’s battery pack but ...

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 ...

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 ...

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 ...

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 ...

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 ...

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.
