3 Claims. (Cl. 123-173) My present invention relates to cylinder covers combustion chamber wall, spark plug depression and particularly to an improved cylinder cover 5, boss 6 extending into the cooling fluid chamber structure adapted to be applied to cylinder blocks below said spark plug depression and having of internal combustion engines for closing the axially thereof bore 1, drilled holes 8 through end of the piston excursion bore thereof and to which studs or screws for securing the cover provide a combustion chamber pocket for such structure to the cylinder block of the engine engines; and the objects of improvements are, extend and cooling fluid circulating holes 9. Nufirst, to provide a cylinder cover of such structure meral Ill designates the combined pressure sealthat will permit an extremely high rate of fuel ing gasket, combustion chamber formin" and 10 charge compression and resultant combustion heat transfer member formed preferably from 10 pressure to be utilized; second, to provide a cylcopper plate and has depressed therein combusinder cover structure in which the high temperation chamber ll comprising a dome-like portion ture produced by combustion of a highly coml3 and extending into the said opening 3, with pressed charge of gaseous fuel within the coma portion extending into the bore 1 of the boss 6;

In my improved cylinder cover structure, I obtain a maximum transfer of heat generated by combustion of the fuel in the combustion spaces of the engine, as the copper, from which the combustion chamber is preferably made, having a very lowresistance to the flow of heat through it and being directly in contact withthe cooling fluid within the cooling fluid chamber oflers only slight resistance to the transfer of heat to said cooling fluid. Therefore, a much higher rate of compression and consequent high temperature of combustion can be employed, which results in a minimum of fuel consumption by the engine without undue ignition detonation therein and permits a low grade of fuel to be utilized.
Having described my present invention, the rights which I desire to secure are set forth in the following claims, as follows:
1. A cylinder cover structure comprising a cast ferrous metal body having a plane face, and a cooling fluid chamber therein and having an opening extending to said face and a combined pressure sealing gasket, combustion chamber forming and heat transfer member of non-ferrous metal located against the said face of the said metal body and having a combustion chamber formed therein with the walls thereof extending through said opening into the said cooling fluid chamber.
2. A cylinder cover structure comprising a cast ferrous metal body having a plane face, a cooling fluid chamber having an opening extending to said face, a combined pressure sealing gasket, combustion cham and heat transfer member of non-ferrous met located against the face of the said cast metal body and having a combustion chamber formed therein.
. 3. In a cylinder cover structure, the combination comprising a cast ferrous metal body having integral side, top, and bottom walls, with a cooling fluid chamber therebetween, the said bottom wall having an opening extending therethrough with a combined pressure sealing gasket, heat transfer and combustion chamber forming member of non-ferrous metal extending through said opening into the said cooling. fluid chamber and against the said face of the cast ferrous metal body.
