Selfrunning HHO system with 400 Watts additional output

You are correct! In the case of a two stroke engine the cylinder has ports cut out of it. I haven't worked on a two stroke in more than thirty years but if I remember correctly both ports at some point in time are open so yes you kind of get a fuel mixture that wants to go right out the exhaust.. the path of least resistance. I suppose that the weight and density of the gas mixture as compared to the HHO is why there isn't a real problem with gasoline... other than the pure inefficiency of the system!

the best engine for this would be the Wankel engine in a smaller scale a normal 4 stroke has to many losses maybe a boxket style engine might work better

sorry but at the point of ignition no valve should be open and they always fire just after tdc if not then they is a chance the engine could be kicked into reverse

You are right that all the valves must be closed at the point of ignition. A note to those wanting to experiment with timing... if your budget allows get one of them new fangled engines with variable valve timing. The newest generation of these engines is all computer controlled so you can really play with any scenario you'd like.

As for kicking an engine in reverse that wouldn't likely happen. I suppose if it were to fire accidently before top dead center it could begin rotation in the wrong direction but the remainder of the cycles would not continue because all the timings would be off. You'd more than likely suffer from a catastrophic failure before it would start running completely backwards.

you your are right it would only run backwards until moment is lost i wouldent say anything would be damaged maybe a flame out of the carb but other then that not alot

I guess I should correct myself here... what I said above I was thinking in regards to a four stroke... a two stroke engine will in fact run backwards with no problem at all if ignition is given at the correct time.

lol that had sliped by me a 4 stroke wouldent but a 2 stroke in sence would yes
but we wont an effecent engine and well that counts a normal 4 stroke and 2 stroke out maybe a boxer engine or wankel may work best who knows a jet engine my also work but be way to dmn noisy
