Abstract:
In a high pressure internal combustion engine having an engine cylinder and piston that reciprocates in the cylinder with a combustion chamber formed in substantial part by the piston and cylinder;a triple thermal cycle system for improved cooling and combustion comprising: an annular volume surrounding the cylinder with a thermally conductive structural member separating the annular volume and the combustion chamber; a constricted passage connecting the annular volume with the combustion chamber; a water injector positioned on the engine to inject water into the annular volume wherein on compression of air in the combustion chamber during a compression stroke, air enters the annular volume from the combustion chamber and on combustion of fuel in the combustion chamber and injection of water into the annular volume, air re-enters the combustion chamber through the constricted passages.
