Who doesn't love the smoke systems used on airshow airplanes. Anyone out there installed an oil injection into the exhaust of the model T just for fun?
LOL some people's T's already do the same thing as the planes at the airshow and they didn't even have to add a smoke system. It's all I can do to keep mine running like she's supposed to, much less learn some tricks on the side.
Wait a minute!! You're seriously suggesting we inject oil into our exhaust, in order to produce smoke for amusement?!??
I mean, an airplane doing it up in the sky is one thing, but we don't drive our cars in the sky.
Have you given any thought to what happens to the car(s) behind, when oily smoke hits their windshield?
If I were King, I'd outlaw you from even contemplating this insanity!!
The smoke idea is not as bad as you may think! I might slow some of those dumb ass people that try and run you down or run over you because un-attention to their driving.
JUST MY OWN OPINION
Yeah, but once you coat their windshield with oil, they can't see you even if they're paying attention.
And, since it pisses them off, no telling what they might do! Drive-by's, maybe?
Puffs of steam would be better, maybe.
wiki on Skywriting:
The typical smoke generator consists of a pressurized container holding a low viscosity oil, such as Chevron/Texaco "Canopus 13", formerly "Corvus Oil". The oil is injected into the hot exhaust manifold, causing it to vaporize into a huge volume of dense, white smoke.
a 1926 letter to The New York Times one Albert T. Reid wrote:
A newspaper paragraph says skywriting was perfected in England in 1919 and used in the United States the next year. Art Smith, who succeeded Beachey in flying exhibitions at the Panama-Pacific Exposition in San Francisco in 1915, after the latter had been killed, did skywriting, always ending his breathtaking stunts by writing "Good night." This was not a trial exhibition, but a part of every flight, and was always witnessed by thousands.
There was no odor to this "smoke", I imagine it was steam...
Steam from more-or-less pure water would be a far better idea. It wouldn't put an oily film on things - especially the car behind.
Now, how to do it?
A single puff of steam probably wouldn't be too hard. Just inject a mouthfull of water into the exhaust stream. Exactly where would be the best place to inject it, I don't know. The hottest place is the manifold, but injecting water there would probably crack it. Maybe into the pipe just aft of the manifold?
A continuous stream of steam would be a bit harder. Injecting water would tend to cool things, and before long there might not be enough heat to make steam??
I look forward to someone doing some tests, and telling us all an easy way to do this!
A loooooong time ago when I was in high school, one of my buddies got a bunch of us to participate in a goofy parade routine using his Model A. If I remember correctly, part of it was dripping oil on the manifold every so often, stopping the car, and frantically fanning the ensuing smoke. Jumped back in, and away we went. Great fun.
When I bought my 1926 Montana 500 racer it had a gallon can under the seat with a brass pipe leading to the exhaust pipe. There was a button you could press in on the floor board that let you dump oil in to exhaust. At the time this was installed there was 500 mile races in California, Arizona, Colorado and of coarse Montana. I understood that the former owner raced in all of them. The idea was if someone was a little faster than you and pulled in behind you to draft you could smoke him off. I found that the only problem with the set up was when you came in at night you left a stream of oil on the floor of the garage. It didn't take me long to pull the whole set up off the racer.
One of the guys in our T club has a kerosene injector on his exhaust pipe. Drips it in right at the bend below the manifold. As I recall it is a pint sized or so container with a valve. It really pours out the smoke!
i once had a 50' ford 6 with a stuck motor. we took off the head and pounded on the pistons with wood till she broke loose. being dumb kids we thought it was fixed. put it back together with the same head gasket and pulled it down the road to get it started. well, the smoke was incredable!! the exaust was rotten, and holes in the floor made it so you had to hang your head out the window in order to see because the inside was so full of smoke! darn kids!
If done as Tom described, I can't imagine any liquid would be left to come out the tail pipe. Just smoke.
I once added a drip system to drop small amounts of gasoline into the exhaust pipe on my 14 T Runabout but the ensuring flame thrower effect from my tail pipe ignited the near by trees. I decided to stick with the smoke already belching from the engine.
