Title: Six Stroke Engine
Post by: Sandman on March 14, 2006, 01:11:01 PM: http://www.autoweek.com/apps/pbcs.dll/article?AID=/20060227/FREE/302270007/1023/THISWEEKSISSUE

Amazing concept. There's a few motorheads around here. Thots?

This is just part of the stuff that will be happening with internal combustion engines. Seems possible to have a 500 hp engine that gets 50 mpg.

Post by: john9001 on March 14, 2006, 03:24:47 PM: you want engineering breakthrough, check out bombardier/evinrudes fuel injected 2 cycle outboard engine.

less weight
more torque
more mpg
lower emissions
less maintenance

and it's not vaporware, you can buy them now.

But that would mean I'd have to change from my beloved Mercury's.....OK I just won't look.

Title: Six Stroke Engine
Post by: Morpheus on March 14, 2006, 08:19:35 PM: its something that's been talked about alot. No one up till now has been able to come up with a good way to harness the heat/energy that is basicly lost into the atmosphere. Pretty cool.

Post by: RTR on March 15, 2006, 01:17:24 AM: Holy Cow!

Engine if it's only 6 strokes, I have no doubt it's "infamous".

You sure? Have you counted lately?

Oh..wait..wtf am I thinking? Fewer strokes = more sleep for me.

Damnit!

Engine, once again you have proven to me that you are indeed a GENIUS!

<> and KUDOS!

is that on a par 3, 4 or 5?
Title: Six Stroke Engine
Post by: USHilDvl on March 15, 2006, 08:58:13 AM: This looks like a really cool idea, and a potentially big leap in engine efficiency/

Can anybody who's an engine expert tell me how this differs from what I've heard called 'water injection'? I know water injection has been around since the 30's-40's. What is the fundamental difference in Crower's technology?
Title: Six Stroke Engine
Post by: MrRiplEy[H] on March 15, 2006, 11:32:45 AM: Water injection only cools down the mixture going to combustion, crower uses the waste heat to produce a steam engine like extra work cycle if I understood right.
Title: Six Stroke Engine
Post by: Angus on March 15, 2006, 11:45:44 AM: More to combustion technology:
http://www.tct.is. In Icelandic, but has pictures and perhaps an english version.
This is what their carburettor looks like:

Title: Six Stroke Engine
Post by: lazs2 on March 15, 2006, 02:26:17 PM: yep.. water injection cools the mixture during one of the normal 4 strokes of an internal combustion engine where as this thing adds two strokes to the process that make use of waste heat.

Post by: USHilDvl on March 15, 2006, 02:33:23 PM: Thanks, guys...got the basic idea about the extra power stroke concept...just need to see it laid out in more detail. I can't visualize the exact nature of the extra cycles, though I understand the result.

Thanks also for the link. However...it's restricted access, at least to me. Not to worry, though...I can't speak or read a word of Icelandic (although the label on the pic was clear enough!) :D

Anybody able to point me to a drawing/graphic of the process, cycle by cycle?

Thanks again...

Post by: Angus on March 15, 2006, 02:40:46 PM: I know a guy who works on the development. I'll ask if he has something in english ;)

edit: BTW, TCT stands for Total Combustion Technology.
The concept works and is now en route into mass production.
I think Honda is the lucky dealer there.

My wife bought a humidifier just yesterday.
First cars cause golbal warming & now they're going to add the humidity.
I've been missing the east coast summer weather since I moved west....

Typ 4 stroke...

1 Piston down...Intake
2 Piston up...Compression
2.1 Fuel injection
3 Piston down...Burn / Power
4 Piston up...Exhaust

What I get as a 6 stroke...

1 Piston down...Intake
2 Piston up...Compression
2.1 Fuel injection
3 Piston down...Burn / Power
4 Piston up...Exhaust
4.1 Water injection
5 Piston down...Steam expansion / power
6 Piston up...Steam exhaust

and you have to stop every 100 miles to refill your water tank. just like the steam engines did.

Post by: eagl on March 15, 2006, 09:11:01 PM: Read the article, and you find that he expects it'll need about as much water as it does gas. The only issue he sees right away is that he thinks purified water may be required to avoid mineral deposits. The water may blow out carbon buildup but could deposit harder minerals if the water isn't purified.

Gonna take a big research lab to make this concept fly, but hopefully he'll prove it to the point where a major automaker is willing to put the bucks behind the idea to make an actual product.

Or heated water, lol.

Ahemm,,,,a big part of the civilized & car driving population on earth actually do live where it occationally freezes.
