Multi-stage combustion hot-gas/steam pressure-differential parallel-cylinder opposed-piston engine for natural gas, hydrogen and other fuels with integrated electric generator

A five-spindle engine system having a stable center of gravity, comprising:

• a central rotary spindle;
• four rocking spindles, respectively offset by 90 degrees, arranged around the central rotary spindle;
• four opposed pistons, operating in opposite directions in pairs arranged in two parallel cylinders;
• two opposing ones of said four rocking spindles in each case control movements of the four opposed pistons respectively in the two parallel-arranged cylinders by way of a respective rocker assigned to each of the two opposing ones of said rocking spindles, or take up motive energy generated in the opposed pistons to coordinate said motive energy by way of the respective rocking spindles with further drive cylinders;
• and
• one or more radial connecting rods connected between the two rocking spindles and a central eccentric connected to the central rotary spindle to transmit said motive energy to the central rotary spindle, and at the same time, by way of the eccentric, coordinate movement of the two opposing ones of the rocking spindles with the other two of the rocking spindles that are turned by 90 degrees relative to the two opposing ones of the rocking spindles and arranged opposite one another.
