Marine Piston Engines v1.0

Auto Credit Based on Visify's Piston Engine Showroom [GEN-1]

Various types - all have been tested. Limitations are; when a load is applied to most piston engines they tend to fail. For these engines a piston speed of 1 to 1.25 seems to be the limit when fully loaded.

Most can power a vessel to around 25 to 30 mph. Using 2 engines can get a large vessel to around 40 mph.

One engine uses magnets to determine starting rotational direction. The magnets don't seem to have any other benefit after that. More testing to be done for a hybrid piston/magnet engine.

Feel free to use.

    So I have a reasonable handle on what SP can do and/or ways to achieve certain designs/plans, and absolutely open to any ideas etc. also help with testing would be fantastic!

    Yes, it needs to be designed to take into account any SP socifics.

    @ChisP i've tried to make a gearbox before but sp really doesn't like it when i try.

    Hey I’ve been liking recent posts and the opportunity for new engineering applications I would like to help you on future engineering projects and possible testing. I have some suggestions for your bottom fed Thompson and some new ideas it would be great too work with you if you would have me.
    Thanks,
    -Chris P.

    Saw this comment from earlier and just wanted to let you know that you can switch the gears and put the small one on the main shaft and the large one on the secondary shaft to produce more torque@bjac0

    True - at high speed I have had down rate the maximum by 25% to avoid the ocate between two positions issue.

    How'd you figure out the distance from the magnets to parts of the pistons?
    - I put the magnets on a piston and fiddled with them until I found a sweet spot.

    Plus, how'd you make this work without putting a crankshaft in the middle of the piston parts?
    - Not too sure what you mean here, but most things can be done!

    @SpiritusRaptor Come to think of it, the only reason why piston engines used to fail was because they would reciprocate between two positions, not producing a single-directional movement. How'd you figure out the distance from the magnets to parts of the pistons? Plus, how'd you make this work without putting a crankshaft in the middle of the piston parts? Thanks for your time.

    man this is an amazing collection of efficient piston engines that work really well i wish we had more of these being posted in simple planes

    Could you make a prop like this with a diameter of 2 please?

    @SpiritusRaptor ah, that explains why i've been having a hard time pluggin these up to my car..

    Ok, been testing today eg. On a largish boat about 30mph...
    They are probably best suited for marine...

    @SpiritusRaptor how does it fair in high-torque applications?

    I have a hi-speed one just being developed... about 3 speed on the piston

    Guys, don't worry, SpiritusRaptor hasn't lost any of his talent after being gone and not posting for so long, there's nothing to worry about! (Keep creating, you're amazing!)
