The above link, is an animation of the revolutionary "Trump Engine"! The only "ONE-STROKE ENGINE", it is a game changer, that could double fuel economy. Sub systems have been removed for mechanical clarity of operational design. This engine fires all power plates at the same time. Negating the connecting shafts, it forms a square or rectangle in shape, at this point, the maximum pressures are reached, for firing at the center of the radius. The spark plugs appear red in my animation, there are holes in the sliding shafts that equalize the pressures on all power plates. A piston has a known diameter and surface area at top dead center, this motor has no surface area at TDC, but when it expands, that area comes into existence. It is the product of the area size of the power plates, times combustion pressures. It also increases in area, as combustion pressures decrease, this is a very good thing, plus the apex of leverage is where it should be for maximum torque output. On a typical internal combustion, or ICE for short, engine peak combustion pressures occur around 11 degrees from top dead center, and mostly spent after 25 degrees. The piston only travels about 1/2 inch, and that is where all the power is generated and why they are so inefficient. Imagine if you were pedaling a bicycle, and when the pedal was at the top, 12 o'clock position, and you could only move to the 1 o'clock position before you had to stop pushing, it would be very hard to pedal the bike, if not impossible. The Trump Engine is perfectly balanced, and opposing paired, sliding power plates and connectors, offset each other's motion, and that eliminates vibrations. This stores the energy of the sliding shafts, like an elevator's counterweights, or the springs on a garage door. This leverage is key in saving energy and can generate power, even at very low pressures where turbines fail badly. Not just a new engine, but a unique matter pump, that solves many industries inefficiencies.
