Steam Engine Model. Because the working volume in a vee twin alpha cannot be equal to the sum of the swept volumes (one piston is descending whilst the other is still rising) it is necessary to measure the maximum internal volume and the minimum internal volume and subtract one from the other. Here the firing order is 1-4-3-2-1. In the other cylinder, the operating piston controls the variations of the global volume and recovers energy. 1 22mm copper end cap (not shown) 3 aluminium heatsinks from an old TV (scrapyard) 1 piece of resin stock.
