Delaney Power Extractor Engine
« on: 13/03/2008 19:34:43 »
Hi All,
 
I came across this website powerxtractor.com through a friend of mine
and this new engine sounds pretty impressive, but I don't know enough
myself. What do you all think, is it really good as my friend said?
 
Thanks in advance for help

I get the feeling that you are asking this question across lots of fora just to get the site some exposure. If you doubled the power from most engines the excess heat would kill them.

All it is is turning a standard vfour stroke engin into a two stroke engine the power advantages of which heve been known for years.  the big disadvantages of two strokes is that unburned fuel often flows through the engine makeing them much higer pollution which today is not acceptable.

Doesn't sound particularly revolutionary; you can't do a lot of 'forcing' without an extra pump somewhere. You may be getting a bit more than one cylinder's worth of power out of a cylinder but you still need more moving parts, valves etc etc.
Twostrokes only come into their own at each end of the power range. Simple engines for outboards and mowing machines and huge marine engines.
'Power advantage' is a bit of an illusory concept unless you are working to some engine size formula (as in racing). What counts more is maximum power and efficiency.
