Abstract

705,079. Altering physical structure. DAIMLER-BENZ AKT.-GES. May 31, 1951 [Oct. 1, 1948), No. 12971/51. Class 83 (4). [Also in Group XXVII] The most thermally stressed portion or portions of the cylinder b or cylinder-head casting a bounding the combustion space of an internalcombustion engine is or are mechanically consolidated by pressure rolling or by hammering, e.g. by the hammering effect of steel balls. The consolidated portions may comprise the surface k between valves d, e and the surfaces l, m between the valves and the pre-combustion chamber c. The inner wall of the chamber c and the passage f may be similarly treated. Specification 498,909 is referred to.
