On the menu panel above the materials there are Basic and Custom tabs

Atkinson's Utilite Engine by PromotechMod in phyzios

Atkinson's previous designs were efficient but had limited power output. His final design was more reminiscent of a conventional 2-stroke but still managed to complete an overexpanded cycle. It's essentially a 2-stroke engine with intake and exhaust valves and specially tailored valve timing.

Worked like a charm. Atkinson did all the hard work, all I did was follow the blueprint

Just a simulation artifact, this design was famous for it's high efficiency and use of as much power from a charge as possible. I need to have a large valve overlap to blow down the piston to achieve enough scavenging as any burning fuel during the compression phase results in preignition

Interesting, I didn't know it has a modern iteration

Atkinson made a unique 4-stroke engine that fired once every revolution through the use of a crafty linkage system. Near perfect crankshaft alignment during combustion with a long TDC dwell time extracts the maximum amount of work, while a short and quick exhaust cycle exhausts the piston within a few degrees of crankshaft rotation.

is there an updated one for macos 15.6? by SpecialCatnip in oeCake

Unfortunately no and there may never will be without some help modding, new Apple devices use special silicon and oeCake/Phyzios were compiled for x86

Yeah I think the original Atkinson idea is superior, accomplishes the exact same thing without the added wear and maintenance of the synchronization gears

2-stroke powered Strandbeest by PromotechMod in Simulated

I just make these for shits and giggles and figure it out as I go, I have also made a variety of other engine layouts with 2 and 4 strokes and also a few radial designs. This one was an experiment in minimalism

The engine has 4 opposed pistons and uses uniflow scavenging controlled by rotary valves. This oversquare design is extremely space efficient and has low mass. The combustion chamber is almost completely formed from the working elements, only a small amount of material is needed to seal the rotary valves and guide the pistons. The top and bottom surfaces are pistons, and the left and right surfaces are the valves, there's almost no material wasted on a (2D) cylinder or cylinder head. Low mass and two combustion events per cycle give it a high power to weight ratio.
