Abstract

570,968. Combustion chambers. ARNELL, R. S. Feb. 10, 1944, No. 14257/43. [Class 7 (ii)] [Also in Group XXVI] To improve turbulence in an internalcombustion engine, the piston or cylinder head, or both, is or are each formed with an annular semicircular depression 4 having curved ribs 6 extending from a point 5 above the plane of the piston head or to the outer edge of the depression.
