A long time ago I was at a hit and miss show and there was a guy there that had an engine made of pyrex, he said it was a training aid for a high school shop class back in the early 70's. Its was neat to watch it run.
Neat video. I guess if you ran out of gas you could run a hose from your Prest-o-lite tank to the carburetor. Or, maybe not, but still an interesting video.
Prest-O-Light did have a setup to provide self starting to engines without electric starting motors.
And a thread about them:
One of the things I was surprised to learn (in flight school) was that there are no actual "explosions" taking place in an internal combustion engine. _That seemed counterintuitive, given what I've known about the nature of vaporized gasolineóbut okay, scientists and chemists are pretty smart dudes. _As most folks knew before I did, instead of the "explosion" described in the Ford owner's manual, there is a smooth burning which begins at the spark plug and the "flame-front" sweeps its way across the combustion chamber. _That takes a more or less fixed duration of time, which explains why timing needs to be set earlier for a higher engine RPM and later for a lower RPM. _I can intuitively grasp that now, whereas before, when my mistaken belief was in an instantaneous explosion, it didn't make sense.
So, in theory. One removes the spark plug, spray ether into the cylinder. Turn the engine to create compression. If battery ignition, turn on the coil and the engine should start?
Yes, a compression start, or as many folks here call it; a free start.
My Ford dealer was telling me that they are going to be making engines without starters. The brain will know which cly is on TDC and will inject fuel in that cly and spark it to start the engine. Where did they get that from?.
Also, that classroom engine is made by Megatech. Still made today for training. It comes with a dyno.
Here are a couple photos of the Disco brand starter that is fueled by the Prest-O-Lite tank on my Buick. It was factory standard.
