ABSTRACT:
An internal combustion engine having at least one piston cylinder comprising a housing enclosing twin gas injectors and having two inlet openings for separate supply of hydrogen gas and oxygen gas to a combustion chamber of the piston cylinder, two pressure-controlled and time-controlled, electrical inlet valves and associated nozzle needles coupled to the housing, wherein the combustion chamber has an outlet opening for ejection of a combustion product, and a thermolysis catalyst covering the combustion chamber. The thermolysis catalyst includes two hollow cylinders arranged at a distance from one another and concentrically and surrounding an intermediate space. The walls of the hollow cylinders defining the intermediate space have a metal coating for release of the heat of combustion acting on the inner hollow cylinder. The outer hollow cylinder includes an inlet opening for the supply of water, an outlet opening for the release of oxyhydrogen gas and a temperature sensor for control of water supply.
