  • Combustion Methods Of Internal-Combustion Engines (AREA)

Abstract

PURPOSE: To restrain the engine from generation of knocking upon high-load operation and increase the output thereof by a method wherein a recessed part is formed in a part of a squished area at the side neighboring to an ignition play so that the squipped area will never interfere the combustion of mixture.
CONSTITUTION: The spherical recessed part 12 is formed on the wall surface 13 of the combustion chabmer in the squished area 30 at the vicinity of the ignition plug 5 as shwon by the curved line C so that the wall surface 13a is not closed to the ignition point 6 of the ignition plug 5 the substantially spherical recessed part 12 is provided on the wall surface 13 of the combustion chamber neighboring to the ignition plug 5 in a configuration encircling the ignition point 6, therefoce, the combustion chamber wall of low temperature interferring the growth of a flame nucleus will never exist, the growth of the flame necleus may be promoted and good combustion may be obtained.
