How do I use a .bsg file?

2-cil cannon engine

uploaded by oziboy 2 months ago

My take on the cannon engine, I experimented quite a bit.

This one isn't really special, just 2 cilinders 180° from each other and a firing offset by 15°.

I'm struggling with low RPM on my most recent builds, lower displacement does not help achieving higher revolutions, higher displacement does not help achieve greater torque.

I'm making a replica of an engine though and this is pretty much the first step to it although the end product will probably not even remotely look like this

In this build I did alter a few things I didn't do before, but I'm not sure if it made it better or worse
The "connecting rod" I use in my older builds in a triangular shape is not present here, instead I added another slider on the other side to maintain rigidity.
The triangular shape was not good, it ruins the momentum and makes both the revolutions as the torque drop quite a bit.
This time I connected it vertically and another issue that is solved is a sudden boost of power the cannon would give and the engine only "liked" turning a certain direction because of that triangle

Just hold right, it'll spin up, if it doesn't give it a nudge (it only turns one way)

You are using too small a throw for a decent RPM. Plus once you break much over 60 RPM the cannons have trouble igniting consistency. Ive had this issue on some of my engines so i use really heave flywheels. Plus the ignition system you are using is cool, but its really bad when the RPMs jump.

Yes, actually I think we could make some sort of variable timing (for the VVT-I/I-VTI/VTEC fans hehe) using this system, but we just need a way to automatically switch when a certain rpm is reached
After that it would automatically advance or lengthen the firing stroke to ensure firing

I'll try using a larger throw, iirc this is either -0.125 or -0.25, could be -.5 too but I'm not too sure anymore

THERE IS AN ADVANTAGE THOUGH! These cannons ARE less consistent than steam cannons, BUT, using cannons we can redirect the stroke and thus end up gaining power. A steam cannon can't do this because it's expansion based and you can't cut the stroke off after firing, a cannon just fires once which is ideal. I'll make an example very soon,

i use a throw of two and just go for the slower RPM, torque seems to matter more than RPM in besiege until they get better physics. :)

I agree that cannons have much more potential!

A larger throw does mess with the compactness though :/

I could definitely get more torque but I'm unsure whether that's what I really want hahaha
