Miniature camera inside an engine

Gasoline Engine Firing

Cool movie! I've seen a running engine with a quartz viewing port back in the 90s. I feel ripped off though, they didn't show the full exhaust stroke.

 

[Wicked Webby]

Nice find!

 

[TriggerT]

That is pretty cool. Thanks for sharing.

I timed 12 seconds TDC to TDC. Suppose this engine is idling, that would put it about 1/200th actual speed. Look at the vibration in the picture, and think about that (at least) 200 times faster! Granted, it's some kind of tiny optical pickup feeding the camera, but still. . . .

That's not a very high revving engine, I guess it has a lot of torque.

Did you notice the time lapse counter at the lower left corner?

I always expected more of an explosion rather than a burn of the fuel. Granted, sped up, it may well be an explosion.

initial thought.. how crude a system, metal valves slapping seats, sparking a fire like cavemen did... there has to be a better, more efficient way..

Man - that's the coolest

It makes me remember Jr High school science class when the teacher ran a water pump and put a strobe on it. The pump was squirting out 9 drops of water a seconds, and the strobe was blinking 10 times a second, to make it look like slow motion. I think that may be why we don't see a slow motion explosion (combustion) in the cylinder. Even at 200

FPS I'd imagine the fire wouldn't be quite so jerky.

none the less, it's pretty cool.

Mechanic's ****.

You mean those fuzzy pixels that go through a repeating blur? I see a 1 come up as the leading digit once in a while, can't make out anything else. If it's a frame counter, it's not a time count if we don't know the fps.

Now we're arguing about mechanic ****!! :blink:

brings to mind the flame front explanation by jestal...

Funny, that's more or less what I thought when they explained the facts of life to me....you know, the bees and the birds etc.

Let us know when you figure out cold fusion. :dribble:

Yup, and a Hemi too.

:wub: Hey!!! B) "An ion thruster...uses beams of ions"

Ion beams make a ****** earth bound engine but you wouldn't be using a computer without my ionbeams creating the advanced semiconductors that make electronics work. In 1978, working with Nova Associates we developed one of the first advanced pieces of ion implantation equipment.
