New Engine

This thread has stirred up quite a lot of interest and amazement from the younger members. There is an old saying (nothing new under the sun) and that applies here too.

Go here to see the Ariel Square Four engine from 1951 which was effectively two twin cyl engines geared together.
http://www.arielmotorcycles.com/engines.htm

And for the member who asks "why don't the big 3/4 take up these ideas.
I can assure you the big 3 do look at these designs and many more as part of their developement program. On paper they look great, but present huge problems at the casting and machining stage, there are also excessive heat and distortion problems at the centre of these engines.

The only non-standard engine I can think of in recent times, which has made it from the drawing board into a car, is the Rotary Wankel Engine which, to their credit the Mazda company have continued to develop. Even here with a relatively simple design there were huge problems to overcome such as early failure of the Rotor Tip Seals and they had to resort to exotic Ceramic materials and equally exotic tooling to machine them.

I congratulate the inventor from Poland for the work he has done and I hope you all keep thinking, just remember though, if the thing you come up with costs 50c more than the sludge pump they have been turning out since the Model T, it won't get past the first bean counter.

inventor,

I apologize for my remark, it was only meant as a joke. I applaude your honesty by admitting your prototype made less power than the original motor.

As others have posted, on old and new existing motors, 2 stroke and 4 stroke, the design is being used.

Research those motors and improve them.

Again, I apologize and wish the best to you

WELCOME TO HR.COM

I have a question this type is a diesel correct?

has it any application to gas with a spark plug?
(if I missed this in reading ..sorry)

SR66

red 65 I got it as only being a joke but I dident take it like

"blatantly prejudiced and narrow-minded comment "

like the Polish NASCAR racer (that passed away ) that won the race then lapped the track in reverse!! that to me was cool and funny . Driving a car in reverse is a skill that most drivers do not possess

But sometimes we all make comments that might seem off base I don't think that was your intention(I hope I'm correct in my assumption)

Rob,
Jon was right, my mother taught me "if you can't say something nice don't say anything at all" (or I'll wack you beside your head!)

It's been my good fortune to have traveled and lived in many parts of the world, very often American humor doesn't translate as funny

And very often, "serious" is very funny when translated

I'll take you're experience on this on the translation thing I'm sure you correct

language and opposing thumbs is what separates humans from the rest of the animals on this planet humor is a good part of being human I find humor in weird places anyway back to the topic!!

The new engine this man is describing is a variation on this design, he has moved both the valve pistons to the top of the engine. He himself says this new engine can't be patented, the reason why is because this is not a new concept.

JK.
I work in a steel mill and several times one of the ships in our port had electrical problems. If their people could not fix it we would be called to go look at it. I remember being down in the bottom of some ships and its like being inside a motor. You can see the crank and rods out in the open with the pistons in the cylinders on top. Very different form my perspective.

OK , sorry.I see camshaft in another construction (Porsche).
This similar to two stroke engine Commer( different diameter pistons)

Prototype are gas , but this construction is perfect too hight RPM diesel motor.Change compression ratio are very easy- this perfect for diesel and gas too.(change angle between crankshaft)

Saw this site a couple of years ago.............I would think that there would be a lot more friction involved with this design. Can't see that it would make better HP.

Looks cool, but I see too much reciprocating mass, friction and especially too much spent gasses left in the chamber with this design.
There was another one I saw like it too, http://www.scuderigroup.com/technolo..._sideview.html

I dunno its taking a 6 cly reducing the amount of "firing cyl" in 1/2 for 10% increase of efficiency?

am I missing something?

take 100 divide by 2 = 50 + 10% leaves you at 60/100 of what you started with.

seems impractical

That Scudari thing is just a 2 stroke with an extra piston to drive. Can't make any real power.
