5 Stroke Engine

Not a Miller Cycle... Very Unique.

Low Displacement, High Torque

1 Main piston
2 Small Booster Pistons

Whoa, that's really cool

Something was telling me that there was going to be a major change in engine basics pretty soon

Hopefully this works as planned

i wouldnt call it a 5 stroke... you need an even number of strokes in an engine since 2 strokes = 360°

crowers 6 stroke motor is whats really interesting to me

You may start to see this but it may be awhile. The next big thing after everybody gets direct injection is HCCI.

Look at the valve timing... It is actually 5 strokes or events due to the small and large gears.

the way i read it, its 2 small firing pistons and one large helper piston from expanding exhaust gas. meaning the outside pistons are the standard 4 stroke, and the center piston lets in the exhaust, it expands, the its exhaust again.

1)intake 2) compression 3) combustion 4) exhaust into center piston, 5) exhaust out of center piston.

right? still doesn't really make it a 5 stroke.

looks like 2 four strokes running at different timing?

also, given that in the pic it looks like all the cylinders have a single cam actuating all of the exhaust valves, it looks like its a 4 stroke, with 1 piston that moves at 2x the speed of the smaller ones.
also, the smaller pistons have 1 cam operating their valves, and the lobes suggest both valves are open at the same time every time....are they 2 stroke cylinders or something?

there is only 1 crank shaft goin through all 3 pistons how would the middle piston be able to receive the exhaust from both sides, one side at a time. kia makes an inline 3 cylinder motor that gets pretty good gas millage, i forgot the damn name of the car bc it was a rental i had, but it had pretty good pick up for only being a 3 cylinder. this is goin to be a mechanics nightmare. i am interested in it now.

wouldnt it make sence for both the outside pistons to fire at the same time then bleed off to the middle piston since its twice the size of it and the middle one is supposed to be for excess combustion gas? or am i missing something.

Hey, thats pretty cool..

I don't see it being feasible for high horsepower applications due to the high exhaust gas temperatures involved, though.

I would like to hear the exhaust note!
