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 that operates without oil lubrication, comprising:

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