Two positive aspects, or contributions, to the evolution of passenger vehicle engines with far-reaching consequences: a) changes, which permit the omission of costly, energy-consuming cooling devices, b) with simultaneous gain by converting this amount of energy into work; they lie in the fact that the combustion chambers (piston at the top dead centre), which have the smallest possible surface areas, due to cylinder-head and piston-side (spherical) cup-shaped/boundaries, which on the piston side can be flatter or deeper in acordance with the process-dependent >> epsilon , are lined very effectively with thermal insulation, including a certain height of the cylinder wall, either by suitable ceramics (layered, porous), or by shell-like adapted vacuum chambers of thin-walled, corrosion-resistant sheet steel in various embodiments, with intermediate walls which, reflectively treated, are capable of reflecting the radiant heat (thermos flask effect), so that due to the keeping together of virtually the entire combustion heat, compared to an approximately 25% heat dissipation into the cooling water of conventional engines, for the same power the effective expansion potential (output) is produced by the combustion of a correspondingly smaller amount of fuel. The secondary consequence is the completely new design of cylinder head, pistons and cylinders, the latter of which may have (vertical) cooling fins on the stressed piston paths, ...
