Comments on: Free Piston Engine as Efficient as Fuel Cells http://thekneeslider.com/archives/2008/09/30/free-piston-engine-as-efficient-as-fuel-cells/ Motorcycle News for Positive People Fri, 25 May 2012 17:41:02 +0000 hourly 1 http://wordpress.org/?v=3.3.2 By: Ben http://thekneeslider.com/archives/2008/09/30/free-piston-engine-as-efficient-as-fuel-cells/#comment-277303 Ben Thu, 10 Jun 2010 23:32:39 +0000 http://thekneeslider.com/?p=2529#comment-277303 The engine in the diagram appears to be a two stroke engine, but I don't see any component to force air in through the intake. Does this mean that it can operate without forced induction, or was that ommited to simplify the diagram? If I were going to design a car powered by a free piston engine, I'd go for something closer to the original Stelzer motor design, which has supercharging built in... plus, if it's to be used for electrical generation, the linear alternator can be placed further away from the hot components of the engine.

One, this device produces electricity which in turn sends power to an electric motor which turns the wheels of a car, if that is what it is being used for. Two, the pistons will not slap the head because in the chamber there is air. When the piston moves into the chamber this air becomes compressed which acts like an air cushion...or spring. This is a very simple concept which was demonstated by Nikola Tesla and his reciprocating engine design. This motor can also run on compressed air or steam. It doesn't have to use combustion. The real benefit seems to be missed by the designers of this device. This motor can produce a consistent frequency. What this means is that a certain resonating frequency can be established. Harnessing the extra power resulting from the resonance benifit of this device could do more than the simple current it generates as shown. Seems to be a lot of misunderstanding in the comments.

I'm glad the concept hasn't died, but I'm getting anxious to see some real-world applications. This looks like the Stelzer motor that I saw in various mags back in the 80s.

Hawk, you mean this one? http://www.autoblog.com/2005/12/09/bmw-turbosteamer-gets-hot-and-goes/ Perhaps opposed-pole magnets in the heads and the ends of the piston to arrest the stroke and give it a little push back the other way?
