Why can't u make two way port opens when it sucks in air and fuel but closes when combustion happens eliminating 2 stroke and even 4 stroke design
Jet engines do that.Thomasprice said:Why can't u make two way port opens when it sucks in air and fuel but closes when combustion happens eliminating 2 stroke and even 4 stroke design
Good point. I guess that jet engines don't really have a cycle. The pulsejet (buzz bomb) engines do (see https://en.wikipedia.org/wiki/Pulsejet ). Pulsejet engines were also tried in cars and a boat ( see https://en.wikipedia.org/wiki/V-1_flying_bomb#Power_plant )rootone said:Jet engines do that.
A one stroke engine would never return to where it started. The shaft would rotate 180 degrees and then stop. The strokes have to be multiples of 2.Thomasprice said:Why can't u make two way port opens when it sucks in air and fuel but closes when combustion happens eliminating 2 stroke and even 4 stroke design
Absolutely. The 'stroke number' refers to a reciprocating engine. A Wankel Engine, although it doesn't actually have a crank and reciprocating piston etc., still goes through four strokes on the way round. The two stroke engine still has the four functions of induction, compression, ignition and exhaust, and each 'stroke' involves two functions.russ_watters said:A one stroke engine would never return to where it started.
That is how the classic designs work. I suspect the OP is confused about what happens and needs to happen during the strokes.rumborak said:Classic designs wouldn't work, but if you incorporated some kind of "flywheel" that gets accelerated on the downstroke and whose inertia would carry it through the upstroke, I don't see why that couldn't work at least theoretically. It would be like riding a bike but only ever pushing on one of the pedals, which obviously works as I've done it many times.
A one stroke engine is a type of internal combustion engine that completes one full power stroke in a single rotation of the crankshaft. This is achieved by using a symmetrical design where the piston moves in both directions during a single cycle.
One stroke engines achieve higher efficiency by eliminating the need for a separate intake and exhaust stroke. This reduces the number of moving parts and allows for a more direct delivery of fuel and air to the combustion chamber, resulting in better fuel combustion.
A 2 stroke engine completes a power stroke every other rotation of the crankshaft, while a 4 stroke engine completes a power stroke every 4 rotations. 2 stroke engines also use a combination of intake and exhaust ports, while 4 stroke engines use separate valves for intake and exhaust.
One potential drawback of a one stroke engine is that it may not be suitable for all types of vehicles or applications. The symmetrical design may not allow for as much power output as a traditional 4 stroke engine, and it may also require more frequent maintenance due to the increased power output per rotation.
While one stroke engines have been proposed and tested in laboratory settings, they are not currently used in mainstream applications. However, the concept of a one stroke engine has inspired new designs and innovations in traditional 4 stroke engines to increase efficiency and reduce emissions.
