The 5 stroke description is very misleading. It is actually a compacted 4 stroke. A compactor is a device which recovers wasted energy from the exhaust gasses. Traditionally it was always done with a turbine geared to the crank. In this case its the middle cylinder. The principle is sound, however there is a problem. Under light load the middle cylinder will pull a vacuum creating negative work, i.e. it will be less efficient than a conventional 4 stroke. That needs to be sorted.
That's a brilliant idea. Anyone that says otherwise should watch the animation until they get it, or if you just don't get it don't criticize it. It took me a couple times, pausing to watch where all those little dots were going. Kindda like a built in turbo without the associated inefficiencies, I love it!
Who the fuck said fuel was injected a second time? There isn't no "second combustion fuel-injected exhaust gases" you dumb fucks it just expands in another cylinder before being vented out.
It would not work.. Burnt gas cannot reburn,so you would have to have fuel injected in to the low compression cylinder. Even that would be pointless it would use even more fuel! Oh my imagine the carbon build up! Good thinking I do see the logic
Not quite. From what I'm seeing - the hot gasses from the exhaust of the first two cylinders are fed into the middle cylinder to continue expanding. So you get a little more *oomph* from the exhaust since it's still hot. Then that is ejected from the engine entirely.
So essentially you get 2 combustion cycles and three expansion cycles per stroke. Impressive.
if anyone knows some good engine videos shoot them too me please ; especially if there 2jz-gte's .

I don't understand why people think that this is a bad idea...
The name doesn't make much sense, but it's not that bad of an idea...
Please understand, the middle cylinder DOESN'T FIRE.

if you reverse the flow would it act like a turbo charger? therefore increasing compression and efficiency and power?

Hey man that's awesome.....from drawing board to the dyno....some steam engines used same concept.....

the extra energy that it produces will go into turning those expanders anyway more moving parts to service .. good try though

Like MrBurnTec said if it where a large engine perhaps a v8, v10, v12, ect.
eventually the gasses would lack oxygen and would not burn the fuel or burn it inefficiently.
I understand it's a concept and a good one at that. keep up the good work!

but the gasses what have already been burnt are going back into another cycle trying to be burned again for combustion it doesnt make any sense

@GammaCruxis i see where your coming from but you wont get enough oomph from it i dont thing because all it is the gasses doing nothing really

wouldnt this technically be 6 stroke because there are 2 strokes by the center piston for every expanded compression?
