Delaney Power Extractor Engine
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

sounds too expensive right now.
you have to deal with timing the engine to make an advantage of the negative pressure of say 30psi (i have no idea what pressure would actually be needed to get 'close enough' to the ideal vacuum state) sucking on your pistons when they're at BDC. i think that would have to either sap power or lower your compression ratio, depending on how you chose to time it.
to take it further and dodge that bullet, remove the intake valves entirely. put several seals just above BDC in the cylinder wall, and insert the intake/exhuast 'supercharged' (high pressure) blower nozzles here. blow out the exhaust gas with a several blowers, distributed radially around the cylinder wall. then blow fuel in using another or the same blower set. you now have direct injection with improved volumetric fuel distribution, you keep the '2-stroke' advantage, and you dodge the negative pressure problem.
however, you still have to figure out how to get seals that have infinite fatigue life at your rated temperature and pressure.
all this would probably happen at a cost of only $50k per 2.0L engine, provided we can sell at least 10 million units. until that makes sense in our economy, we'll keep buying superchargers and wanting higher octane fuel!
