Ford 3000 - Blueish hue smoke story / question

[Egon]

Didn't some of the "old" tractors have a factory built system to put an ether can in a holder and push a button to blow ether into the intake manifold while you sat on the seat and cranked the engine over!!! I know FORD and Deere had them on some of the larger machines.

Sure did but that is from a remote location. Quite different from spraying into the air intake while standing beside it.

Some cat equipment does..

Plus some tractors have air intakes that are accessable by the driver, while setting in the seat... etc

All true but still does not mean one should be cranking and spraying unless one is remote from the blast path!

Look at the way starter fluid works. It is much much easier to compression ignite than diesel. If you spray in several seconds of it into intake THEN crank, the first cylinder will get the majority of the shot. The either ignites while the piston is on the way UP making combustion pressure rise dramatically. The diesel that is coating the piston ignite raising the cylinder pressure even more as the piston continues to rise up. The normal fuel is then injected and immediately ignites rather than the normal slow controlled ignition. If you are "lucky" the engine starts. If you are "Unlucky" and sprayed in too much fluid or had all of it in 1 cylinder, you can blow the ring lands off and crack the piston skirts even bend the connecting rod.


Ether addicted engines have one or more compression ring lands hammered off. Pull some down and study them. I have, that's why I only will ever spray ether into a cranking engine so the ether is spread across several cylinders and the dose is limited. But that is only as a last resort.

Other folks have other opinions and as they say YMMV

No, I agree.. I've seen ether adicted pistons.. just like you say.. set back and broke ring lands.. holes pistons.. etc.. never see good parts coming out of a worn out ether addict..

Is this a new form of selective fluid dynamics under differential pressure?

NOPE! Just the right way to do things when you want to get a job done safely and don't get hung up on mis-applied theory.

Yup I did mention that once and then was baffled by some of that miss applied theory that got quoted.

"miss applied" who is she?

Not sure, but obviously Canadian, as they're more familiar with her than we are!
