Nitro Engine Pollution?
 

Just out of curiosity, what kind of emmissions do these little engines put out. I am sure that the big gasolines are pretty bad but how about our methane based engines?

RE: Nitro Engine Polution?
 

They put out the same stuff all combustion engines do; carbon monoxide, carbon dioxide, water, unburnt oil and so on.
But you will spew out more pollutants from your car than you will ever from your model airplane engine. Even your lawn mower will produce more pollution.

Its a matter of scale. We modelers are on the almost unmeasurable level. If you are concerned go electric -- oops I forgot about all those coal fired power plants needed to provide the energy to charge up the batteries. And the batteries, where to dispose of them? Pollution everywhere!

So I guess you are dammed if you do and dammed if you don't. I guess you will have to go in for slope gliding.

Cheers,

I remember reading that lawn equipment and motorcycles and whatnot have been reported to emit much more pollution per unit of fuel burned than the worst of the street legal vehicles we drive. I would imagine if this is the case the gassers on our models are even worse. I have no idea how bad methanol would be, though I've always been under the impression it is cleaner burning than petrol.

RE: Nitro Engine Polution?
 

Yes the methanol is clean burning, but try to breathe below a hovering helicopter or close by[X(], they spew out alot of smoke and most of it is oilfumes, but it is peanuts in the big picture

RE: Nitro Engine Polution?
 

....it's the hydrocarbons from our oil that is bad. If you measured a car burning gasoline
going down the street, and a model aeroplane flying along right beside it.....the aeroplane
would be putting out about a hundred times more pollution than the car. [X(]

EDIT>>>...a clean burning California car that is. ;)

FBD. ;)

RE: Nitro Engine Polution?
 

....if you scaled up the size of our tiny engine displacemant, say a .60 size engine
( 6/10 of one cubic inch) up to ths size of a 350 Chevy engine.... which would be
about the equivalent of 500 .60 size engines.....

....it would put put out more smog than a few thousand auto engines. [:@]

RE: Nitro Engine Polution?
 

Yes, a friend of mine is creating smog on our field when running his raptor 50 on 30/23 fuel. I never stop beeing impressed by how much smoke those heliengines can spew out. I will not get too surprised if my greedy government some day put a new tax on glowfuel here in Norway and cover behind the environmental case.

RE: Nitro Engine Polution?
 

Interesting, i figured because our exhaust pipes have no kind of catalitinc converter and emission regulations that they would be much worse (to scale) than our conventional car engines. I am a little more curious as to the difference between methanal and gasoline. Lets say we have a 30cc glow and 30cc gas. What would have worse emissions. Also, does the longer flight times of gasoline dampen any differences.

I am not worried but thaught of it this morning and didn't really no the answer. Should be an interesting thread no less.

RE: Nitro Engine Polution?
 

The cleanest burning gasoline engine, such as ultra-low emission engines(thank you Honda) still produce CO2 as much as cars from the mid 80's. They have just managed to get rid of most of the other crap that was in the exhaust, so now we breath clean air but will die from global warming. Oh, and our rc engines would put out a itty bitty fraction of the CO2 produced by the Honda.

RE: Nitro Engine Polution?
 

I do not know which of the thousands of potential causes will bring about my death, but I am quite sure it will not be global warming;).

....let's keep the topic on nitro engine pollution. ;)

RE: Nitro Engine Polution?
 

I don't think that's gonna kill me either, but do you differentiate between a "nitro engine" and a "glow engine" running on 0% nitro?[8D]

RE: Nitro Engine Polution?
 

With regards to heli engines and fuel, I was under the impression that heli fuel is designed to produce more smoke so that you can tell if your engine has quit.

RE: Nitro Engine Polution?
 

I recall the AMA interacted with the EPA some years ago on this matter and convinced the EPA that we were small and insignificant and not worth regulating. Sometimes it is good to be small and insignificant.[8D]

If I am right on this California does not allow the sale of 2 stk lawn equiptment any more has to be 4 stroke no gas/oil mix ,martin

bottom line however I do not think our little engines create an issue here and I fly diesels and 4 strk glow martin


the "least problem" may be with FAI fuel no nitro

RE: Nitro Engine Polution?
 

california wont allow little 2 stroke engines anymore which was widely used for lawn equipment, but those big huge refineries can belch out 30 tons
of soot in the air and thats ok. im so glad im gone from that hell hole. hope it falls in the ocean. L.A. was just voted number 1 worst place to live. it was in last weeks paper. good bye for ever

Thank goodness that O.S. Max is coming to save us all with the .55 AX biofuel edition!

RE: Nitro Engine Polution?
 

I gotta wonder what puts out more pollutants, all the model airplane engines ran in a year or a G5 taking Al Gore cross-country...

RE: Nitro Engine Polution?
 

Lol, that is nifty. I wonder how it will run?

RE: Nitro Engine Polution?
 

LOL, I wonder how it runs?

Ya no what i just noticed. I am aproaching post 1000. Cool :D:D

RE: Nitro Engine Pollution?
 

Hey thats not nice, I'm still stuck in this sewer.

RE: Nitro Engine Pollution?
 

In reply to cambo I prefer quality to quantity:D

RE: Nitro Engine Polution?
 

I bet that would run pretty good though slightly less power then the meth versions. Ethanol has one additional CH3 group added to a methanol which makes the fuel burn a little slower and with a little less vigor but the difference shouldn't be really noticeable if the engine is designed for it.
