New 4 stroke engine (en anglais)

[Cuicui]

Génial pour remplacer la fusée de la 206 à eau...

[inventor]

If don't like a" short valve", put at valve "squarer" valve piston:
Square Valve Piston

Most advantages this conception :easy water coled piston (especial exhaust) , eliminates piston rocking ,roller bearings slide piston , etc.
View:Pivotal Piston

Colling water piston made very low NOx,;Please, use from catalysts platinum for electrolyze

Sorry , I live 30 years in "piston valve reality"

Possible mutation:
Pivot piston little modification. Using in four-stroke “piston “ square valve.

One big advantage have “piston Pivotâ€￾. Pistons not have force: Nm !!!
This reaction is only in bearing piston !!

Another, piston no need lubrication, lubrication only need “Ringsâ€￾ (sliding seals)
Next my modification: sliding seals put no in piston. This seals put in cylinder!!
Advantages: cylinder are LIFETIME , maby building only aluminum cast.
Because on cylinder no sliding piston and seals, made aluminum, excellent conduct heat !!
But piston must make steel cast. (Or steel surface)
Then piston and seals only need change at refit engine, without any mechanical enginery.
Theoretical, only need to change part to repair engine!
In this version lubrications are need only seals, sure much little in conventional piston.
Ecology are happy,when seals made Teflon and engine no need oil
Are you like square pistons now ?? :rolleyes: :D

[inventor]

A like square piston , and don't like many rod and long crankshaft::D:D
Simple engine:










Two stroke mutation:

Without oil when teflon seals.

Some other details:



Example seals: no oil, Teflon or VITON®

je vais traduire les explications de inventor et les poster en français sur le forum, faut un peu de temps c tout , ça servira à tous

j 'ai visité son site et y aura des choses à adapter c sur mais oas impossible

à choisir, je préférais le moteur à 3 pistons. si on en est aux pistons de formes bizares, autant passer à la quasiturbine, non ?

Dans grand échelle graduée êtes mieux voyons avantages ou inconvénient

A quoi sert le petit vilbrequin au bout? à faire plus joli ou à rassurer les boites d'usinages?
