6-stroke engine

[manofthefield]

May just be a pipe dream (most new engine concepts never see the light of day), but still pretty interesting to read.  And you never know, it could be the future of IC engines

If it (my 6-stroke engine) turns out to be great, fine. If it doesn't, it's just another year out of my life that I've had a lot of fun doing something.

Did ya'll know that gullible has been taken out of the dictionary?m

That would be great for some things...  I can't imagine that Alaskans will be getting in line for 'em...  But, Texans probably will.   

Long-haul trucks would be the best place...   That would be odd to see a truck filling up with 100 gal of fuel and a 100 gal of water.

The 6-stroke engine is older than the Diesel engine.  Nothing new there.  A hybrid steam-cycle internal combustion engine?  Hmm...  The inefficiencies of the cycle would melt my calculator.  Let's not forget that distilled water is condensed steam.  Ooops!  That's gotta put a dent in the system efficiency figures...   

He has all those dynos available and he doesn't know what the specific output is?  Bullshit. Until he posts data it's just another perpetual motion machine.

It's a publicity stunt by another hotrod builder.  Hotrod builders are known for their horse shaZam! and their publicity stunts.

Rolls royce has built and even sold them. The problem becomes pretty acute when the whole damn world is buying distilled water, it will start costing as much as gasoline. Anyway its better to burn it than gasoline anyday of the week. Now with nikasil and other crap they can coat cylinder walls, with rolls royce's biggest problem (corrosion of rings and cylinder walls due to water) might be eliminated. Start by finding a way of putting in regular water not distilled, and it will start to solve problems.
However I dont agree that trucks will be your best choice for this, I happen to believe motorcycles are. They are going to be the easiest to plumb in water jets and suffer the least losses when it craps out. OK OK lawn mowers first, then motorcycles. No reason a GS cant be both I always say.
Cool.

I was surfing the web during lunch and found this:

http://www.sixstroke.com/docs/amc_may_1998.pdf

It's a little more along the lines of a conventional double-acting engine but with a 6-stroke twist.  It actually makes a motorcycle go, so that's a step in the right direction.   I'd still like to see some real data...

I don't understand this statement, as far as I know being distilled doesn't affect the properties of water in any real way.  The boiling point doesn't change (no matter what myths might tell you) and it will still expand the same amount when vaporized.

He has all those dynos available and he doesn't know what the specific output is?  Bullshit. Until he posts data it's just another perpetual motion machine.

Amen!  All too often we see these mythical machines that are supposed to completely revolutionize our world and they always turn out to be hog-wash.  Usually, its a poorly thought out concept by someone with no real engineering experience.

I think what GeeP is saying is that it takes more energy to create the distilled water than this guy can get out of it in his engine.

Yes, steam distilled water is $$$ if you start needing a few trillion gallons a day.
Now distilled water is only needed to keep water from eating the insides of the motor, so use uncorrodeable (heck that's not even a word, so forget that actually existing) materials and you're good.
The third problem is, water squirted into the motor will turn into steam with motor heat and give you power yes, if you know how long that will take ... and at 6,000 rpm guess what, it will have to happen 100 times a second ... good luck with that. Yea heat is in the solid surfaces, like walls and pistons, and squirting it into the chamber will do you a fat lot of good, and spray the walls and you lose lube and eat the motor that way.
The Rolls used to send it in along with the gasoline (separate injector) and combustion process lit up the water and gave you higher power right in the same stroke. Much quicker and no problems with washing the oil off the walls. I believe you would still have to run water less for a few mins before shutting off, and waterless when its warming up. Freezing will be a non issue as well if you did that. Engine heat should warm it up plenty using a sort of water jacket of sorts but something that can expand with ice instead of crack like a regular cyl head.

And I'm pretty sure we've done the basic lab in any basic chem class to demonstrate freezing point depression and boiling point elevation by addition of solute.

[aaronstj]

Not by terribly much, though.  A solution with a specific gravity of 1.060 will still boil at about 220* F.  And that's a fairly thick solution.

(The rest of the homebrewers in here should agree.)

The guy is just after publicity..... and its worked. I have never heard of him but after reading the article not only have I been told about his "Revolutionary new engine" I now also know all about him, his background and his line of work!! His ideas and theories regarding this engine have more holes in them than a Welders t-shirt! Ford, GM MB....all the big players have tinkered with this idea before and all have dismissed it. The days of solitary Engineers working in their sheds at home and making ground breaking discoveries finished in the early part of the last century.

Somebody hasn't been wearing their leathers...   

I'm going to find an application for that quote tomorrow.

Spot on!

I reserve judgment until I see definitive proof.

Geep.
We will call it a fair swap mate. I have been quoting your " Extra zero on the tolerance" line for some time now and getting quite a few laughs in return.

[GeeP]

hehehe  Glad you like it.
