The new 4 stroke engine

[Initial D.oug]

interesting read. Wonder what's happening with it now.

That's really interesting. Looks to me like in the process of trying to simplify the engine he's made it more complicated.

Pivot cylinder are made possible extrude big aluminium profile

One photo exhaust window. In hottest place in window,can you see a coal.

the only problem with that design is that once the engine heats up and gets into the higher revs the metal expands. then the stroker becomes a little longer and you've destroyed your engine.
another thing is you would have problems with pistons rings on the overhead pistons because once you pass the opening there is the chance of a ring catching on the ridge of the exhaust or intake port destroying your rings.

Yes, you right.This "mechanical art " simile two stroke engine.But in this example, its easy, because, piston is excellent colled oil in upper craksbox.But rings are need made height- in my example 5 mm ( !! ,L type rings).And cathing is very little. And few part of window.

Yoy are have most popular forname in Polish, are too speak polish?

[kowalski]

you'd get enough rubbing that you would get a lot of blow by after a few thousand km's... I'm not polish, my background is German. The name comes from an excellent movie, vanishing point. Excellent driving movie.

Oh yes ,I see,excellent driving movie.

In big ships or energetic engine are similar problem -many this engine are two stoke-but working some tens thousands hour . I think ,so this problem are resolved.
Thanks for professional develop problem

Version for small engine air-cooled:



:idea:
Develop air-cooled half rotate piston :
Two big closed bearings,little different seals:
(3D not enough, two picture for good explain )




Plus some fin inside "piston" and good air vent.

Or two small bearings .....

I first saw that Coates rotary valve idea a couple years ago. It looks like it has a lot of potential, gets rid of the camshafts, and the reciprocating valves. An engine with one of those could really raise the rpm limit! Provided you could keep the bottom end together.

[Feliks]

Yes , you right, "bottom"' are in " " , becouse are pssible "boxer " version-- true boxer . Power possible take at "upper "- crankshaft no need hight rpm at clutch and gearbox.

At one discus about damper athis enengy , I propose linear dynamo simile linear stepper princip http://zone.ni.com/devzone/cda/ph/p/id/133#toc1

Some pictures about this innovation:




Are possible 100 pcs in 1 square meter, =~~ 5 KW one meter

1 km ^2 = ~~ 5000 MW

ps. sail -boat with this innovation obvious name wave-boat

In car are possible electric variable last absorber shock or computer current digital regulated

You do not know accidentally where disappear two small valve pistons ???

Special electric "Damper":

Each wheel singly are possible "hand weight", operation switch and give necessary portion pulses. Pilot (partner)no need circus game work at 4x4

In F1 each wheel are possible tuning too maximum adhesion.

New oscillating stepper engine:



Version "Stephenson 3 E"

For modifications "old machines" without gears
