Abstract

1468800 IC engine cylinders DOXFORD HAWTHORN RESEARCH SERVICES Ltd and E P CROWDY 25 June 1974 [27 June 1973] 30458/73 Heading F1B [Also in Division F2] In order to ensure, in a reciprocating piston engine, that pressure differentials are evenly distributed between the rings of a pack of piston rings 4, by-pass grooves 3 in the cylinder wall form controlled gas leakage paths to the interspaces between the rings. In a fuel injection I.C. engine, an annular groove 5 may be provided in the piston head or cylinder wall so that the air, which it contains, rather than combustion gases, is blown along the leakage path.
