The world´s first Three-stroke engine, pre-test

This is a pre-test of the world´s first three-stroke engine. This is my and one of my classmates finalexam at Miduniversíty in Östersund, Sweden. This principle is patended by Nils-Johan Nilsson.
Soon we will make some more tests and the video will be here soon after that. subscribe to see the result of this brand new engine type.

interesting concept !

[RenzeZielman]

How do you achieve 3 strokes ? shouldnt it be an even number, because for every downstroke there should be an upstroke ?

[romandybala]

Why?

[robinhooodvsyou]

-Strokes are the movements of the piston.

-Cycles are the "functions" of an engine (intake,compression,combustion­,exhaust).

-So I think it`s more like 3-cycle, much like the "Lenoir cycle"-engine is, if you know what I mean.

i something called a shuttlecock engine. in an old encyclopeadia. It was two heads with one cylinder bore and a free floating double haeded piston that jsut went back and forth . It had no crank the idea was to hook up a crank to an exahust tutbo and run it of the back pressure from the piston. i think they used it in briton on buses and wierd stuff like generators and bots cant find it on line. mabey its called something else on line think it was the 1978 britanica,

@furmaster212 because it utalizes the empty space left underneath each piston that a four stroke does not, by fireing each side of the cylinder! :)

[furmaster212]

well im high risght now but i usually understand things better when i am, here is how i see it, if each piston can be fired on both the top and bottom of the piston all in one sleive, and alternate eachother every other stroke, makeing a 3 stroke....its a good idea because an engine the size of a typical inline four now has the displacement of a 8 cylinder motor but still at a four cylinder size!

To TRUELY have an odd numbered cycle engine there would have to be a spark plug and intake at the top and bottom of the cylinder. OR two pistons on opposing ends of a connecting rod with separate carbeuration/intake/ignition. . . and anyways it would make no sense. Just because something CAN be done does not mean it should. And @GGGG761 , a 1 stroke is not even possible. . . well. . . it is, but it sure wouldn't haul ass. . . it would send the piston down. . . and there it would sit.

34 seconds of my life wasted

[princepersia1]

why build a 3 stroke its just stupid, what a waste of time old fart

[GGGG761]

build a 1 stroke engine that thing will hall ass

[Snoep76239]

How about an explanation of how it works w/three strokes? Interesting concept....
