New Diesel engine

Has anybody see this.

Man this guy might just disappear one day. Interesting stuff.

I saw this at the LA car show, in the "underground" area for selling aftermarket stuff. The video on the website is what I saw.

I don't know enough about engines to say if it viable or emissions clean.

No news since April 2006. Not a good sign.

this doesn't sound quite right, for example:

Through two revolutions of its crankshaft, the ME firing cycle is equivalent to a 32 cylinder reciprocating engine, that is, it fires 32 times

but later he says it is a four stroke cycle engine. So the spark plug is firing 31 times into an already combusted mixture?

Also,

Pistons travel only the same direction. No reciprocation, only stop and go.

What does this even mean?

The ME has no valve --just open ports with no restriction. Air flow action is one way.

How can you compress the mixture if there are just open ports?



This whole thing just leaves a lot unanswered.

Did you look at these videos :

They look cool to me, but I don't know that is going on.

This is where I wish I was a gear-head instead of a keyboard-jockey, .

looks like there's two sets of 4 "pistons" and they each advance about 1/8th of a revolution till it nearly hits the other set, then setting the other into motion, constantly leapfrogging eachother 1/8th rpm at a time.
What I'm wondering is how that engine can cope with cooling if it's constantly firing off 32 times per revolution. That's a lot of heat for a small package.
That and in order for the "leapfrogging" to take place, the piston sets would have to have one hell of a strong ratchet system, one that could handle the claimed 850 pound-feet of torque. Not only that but it would have to handle it quickly as one set of pistons would finish the "power stroke" and immediately slam to a stop and cope with the torque of the other set of pistons firing their "power stroke"

Looks like the valves would be an easy matter, just put them in the side of the cylinder wall, like a Wankel.

The basic design is not new.
It was originally suggested in the early 1900's when the piston engine was still as much a curiosity as a viable means of propulsion.

LJK Setright details the basic design in his book : "Some unusual engines" for those interested.

The basic unsolved problems way back then revolved around the ratchet gear to convert the power from linear to rotary and suitable lubrication for the internals.

No idea if they have been sorted or not but a quick dyno run by an independent lab should provide a few answers.

Cheers , Pete.

No, I hadn't seen the video section, but that doesn't clear a lot up for me. I'm not a gear hear either, so I can't be really certain if the things this guy says are specifically possible or correct. But from what I do know, it just doesn't sound right. But as peter says, an independent lab can easily test the claims this guy is making, so I'm sure we'll find out eventually.

seen 'em come and seen 'em go, when they make one that works longer than a demo for investors you'll see it on the road.
