New engine

Check out the Dec, 2008 video of this new diesel engine. Pretty cool

That is really interesting. I've been waiting for someone to come up with an entirely new sort of internal combustion engine, like mr. Wankel did.
It seem like we have pushed the "normal" enginetype as far as it'll go.
This may be the answer.

 

[Mr. Sir]

Looks like a very efficient design. Cool!

I still like this one though: <object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/0EA079zrhv0&hl=en&fs=1&color1=0x2b405b&color2=0x6b8ab6"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/0EA079zrhv0&hl=en&fs=1&color1=0x2b405b&color2=0x6b8ab6" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>

I wonder how readily it'll be accepted. Cool!

Interesting. 2 rod and pistons per cylinder. If it doesnt get more compression, I wonder if it's worth the extra friction, journals, machining etc.

 

[stehansen]

I guess it's a 2 cycle right? Also it would act like a short stroke motor but by having both pistons come together have the long stroke necessary for the high compression of a diesel motor.

Very interesting!

It's a 2 stroke so compared to a 4 stroke with the same number of cylinders, the friction would be similar.

Jerry, that looks similar to an 80's concept called the Collins engine. It was supposed to turn the world upside down, 100 mpg+

I remember seeing a video of the Collins engine back then, but it was a gas engine. It was very similar to what you posted.

I Googled it and it seems the Collins engine fell off the face of the earth.

It may appear to be new but the idea is not . Radially opposed two cycle diesels have been around for decades but they used two crankshafts,top and bottom where this one uses one .

The Fairbanks -Morse FM 10 d 8 1/8 inch was a 10 cylinder twenty piston engine used both for railway power plus saw much marine use .It was one of the engines used on WW2 vintage diesel electric submarines as well as for escort destoyers and auxileries on larger ships for power generation etc .

I didn't pay much attention but most two cycle ported cylinder diesels need a scavanging air blower to work .I don't know if this one has same or not .

Follow the bouncing link, Al.

It does have an electronic activated turbo, Which can eliminate turbo lag.

 

[Al Smith]

I tried to but I could not detect an air source .I saw the ports etc .I did read a bit about them talked about a turbo charger but weather it was incorperated in that engine,it didn't say. I'll look again .

 

[Fiddler]

It is supposed to have be coupled w an electric tubo charger. There are two little speeches by the CEO of the company that explain it.

 

[Al Smith]

I also detected something going back and forth on the very inside of the crankshaft .I might assume it could be a scavanging air piston which acts like a turbo to a point .
Maybe so ,maybe not .If so though that design goes way back to Cooper-Bessemer .

The turbo makes more sense though . What that other thing is,is a good question .

 

[gf beranek]

It's odd how certain technologies were shelved years ago and lost in the mainstream. Only to re-emerge many years later in a high tech form.

 

[Al Smith]

How very true that is .Reminds me of the first Sherman tank engine I ever saw. Built by Ford in 1937 and it was an overhead cam engine .

OHC engines never made mainstream until the late 70's early 80's for automobiles .

[BlackSmith]

puts me in mind of a Lister TS3

.

Were you working there then too?

you mean this one???? http://www.youtube.com/watch?v=P2eHkmXAJqM this one was for the closing end of ww2---it hauled mail......1100 cu in-v8!! tank boys loved it--
