Algodoo

Nice! The sprocket geometry looks perfect 10/10

Nice this is one of the fastest spawn engines I have seen

Hi Dare, nice concept, I'm pretty sure you have seen this:
http://www.algodoo.com/algobox/details.php?id=46380
I have spent quite a bit of time working on collision based engines and I have found lasers dont work all that well for triggering fast actions
Pure on collide works better IMHO
Kilinich's ball piston, no rods engine is the best for performance but does lack realism?
A realistic rotary would be cool

Good start

Fairly nice Why didnt you put the crankshaft in line with the cylinders

Very nice, however the valve timing is all messed up, the cam ring needs to also rotate at 1/2 the engine speed and the cylinders should fire alternately every other revolution to be totaly realistic Check out the timing on my radial here:
http://www.algodoo.com/algobox/details.php?id=36340
Even though mine is a radial and not a rotary the principal is exactly the same!
Still 10/10 for great artwork and engineering but can be improved

Nice Job

Pretty nice, not sure what all the extra length in the cylinder is doing for you?
The upper and lower horizontal black rods dont seem to do anything?
I think if you clean it up a bit it will be realy nice 8/10
A true govenor is tough to do in Algodoo

Very cool as always Bill 10/10
I'm getting back into RC helis too, hovering a Novus 125 CP pretty well now LOL

Nice power

Cool Check out this one:

Very nice but not realy that fast still a 10

Cool If you increase the density of the rods and crankpins to 100 it stays together and runs better

I'm realy surprized you didn't ballance this

Very Cool

FAST

Very Cool

Good speed on the engine

I think the point is to ensure that it spawns at the correct time in the stroke
With a few exeptions most spawn engines on here waste a lot of power by spawning too early, discuss

Nice you could vary the timing for throttle.
I have been trying to follow the comments with google translate

if you switch the pistons to boxes instead of polygons it works much better
also the polygon timing gears will not handle the speed this engine is capable of with a little tuning
This has a LOT of potential

The 4 stroke timing on the original was the COOL part
Making a 2 stroke out of it is a step backwards

@Bill it will be collision type and possibly also spawn hybrid

@Dare of course it will have full mechanical fairly accurate valve timing

I just posted it here so I can mess with it at work if I get a chance

Thanks Bill, it probly has too many parts to run well but I'm gonna try anyway
PS I didnt think stuff from the work in progress section was suposed to show up in the highlighted scenes?

Nice

Very cool mechanical govenor I may have to borrow this idea
I will give you credit of course 10/10

Hi Dare, I have checked this on 3 different computers and the timing is right or
at least real close? This is a true 4 stroke engine and each cylinder only "fires"
once every other revolution. cylinders are numbered counter clockwise from the
top center and the firing order is 1,3,5,7,9,2,4,6,8
The cam ring turns at 1/8 crank speed. This is accurate and realistic to the real engine.
Help me out here Bill

Hi Dare, the engine itself is almost done but I need to do the in scene controls box
and the write up for the description. I will try and explane it LOL

Runs great I like it

Kick ass RPM and smoothness
