Re: CC sealing ?
 

But since the piston still travels all the way down, wouldnt it still pick up oil and leave some in the combustion chamber? I dont know enough about it to say its a good or bad idea really...but i think it would be more widely used if it was a viable option for big displacement, long-life ----.

You sir are ------- ignorant. Just because somebody doesn't ---- with RC airplanes they're morons?

I think you're the ------- moron here trying to talk like ABC non ringed glow fuel engines are god's gift to man and NEVER need maintenance and NEVER wear out. Fact of the matter is that they wear out much faster than a ringed engine.

You honestly think half of the people that drive cars even know what running rich is? Do you think they care? What happens if their car happens to run rich one day because of a weather or pressure change?

You can't just throw out a valid argument because "car people are god damned morons." It's a generalization, and a bad one at that. Car engines are put through much more stress than plane engines. If you want to argue that we should use ABC non ringed engines in CARS, you might want to go off of the track record these engines have in smaller scale cars rather than the track record they have in airplanes. And stop ------ing misinformation, these engines run just as shitty on a mixture that's too lean as they do a mixture that's too rich. You say it's just gravy if you run them lean, but did you forget that in a 2 stroke the oil is in the fuel? It means the engine runs hotter with less lubrication, how do you intend to get your bearings oil so you can be "moist vagina" if you're running it lean?

If you run an ABC 2 stroke non ringed engine the way you say, retarded ass lean - you'll seize the piston in the sleeve, make the glow plug element melt and cause scoring in the sleeve, or rape the bearings.

As for you, keep the pink dildos to yourself you ------- faggot and keep that weak ass ---- to yourself.

what a ------- idiot^^

Re: CC sealing ?
 

It would require some very expensive machining. More expensive materials. And oil in the fuel. Its not going to happen. I don't see really any benefit. I doubt it would last as long or be lower friction. Most of the time when something works in small scale it can't directly be translated to a larger model. Nondimensionalization.

Re: CC sealing ?
 

It wouldn't require oil in fuel... Small engines have no oil sumps or pumps, they simply suck the oil in the fuel to save weight.

Re: CC sealing ?
 

No. A ringless engine would require oil in the fuel. You would need plenty of lubrication in the upper cylinder or this thing wouldn't last long at all.

Re: CC sealing ?
 

Also did you forget that these 2 strokes have no valves? Sure you could boost it but the fact that the intake and exhaust are open simultaneously with no way to adjust how long they are both open, it isn't exactly optimal.

The bottom line is that there are too many drawbacks and not enough tangible benefits.

I would suggest you research 2 stroke engine technology before further proving your ignorance.
