237 this big lump of metal should not be there.! the hot side connecting rod should be a bit longer. maybe the cold one too. it appears that the (low-mass aluminum) flywheel has a less-effective distribution of mass (dom). d
as you can see in the video, the valve is controlling the flow between the cylinders. this is an effective way to control the RPM. This is actually the only way I have seen to control the RPM. A friction brake would not be nearly as accurate, and it would also require a lot more parts.
023 WHY ?!?! if you want speed control just put a variable friction brake on the flywheel or crankshaft. ( you may know that in the real world, the rpms of a (low-torque) prime mover are determined by its load and how it is loaded. said another way, the engine's/prime mover's specs are 'matched to' an optimal load and power take-off mechanism. ) 129 !?!? the stock engine base acts as a resonator. so, the engine still seems noisy. a heat engine is Supposed to be made in such a way that lubricant is NOT needed. this is accomplished via the Strategic use of metals of differing hardness. this is why a correctly made heat engine has components made of steel and aluminum and brass. you may know that, without doing anything else, an elongated duct acts as a regenerator. and, a vertically oriented loop in the duct that is slightly taller than the cold cylinder acts as a convective heat trap. d
