  • Combustion Methods Of Internal-Combustion Engines (AREA)

Abstract

PURPOSE: To secure stable combustion and accelerate faster combustion speed by constituting squish area between cylinder head inner wall and piston to generated cyclone flow within the combustion chamber.
CONSTITUTION: With a piston 2 reached the top dead center, a flat annular squish area S is formed between annular flat surface 12 in the cylinder inner wall and piston top annular flat surface 13. Further, a glove-shaped shell squish area T is formed between the bottom wall 16a of cylinder head protrusion and spherical back surface 18 of the piston 2. Wiht a piston 2 risen to reach close to the top dead point, squish flow F, G is injected from squish area ST to generate cyclone flow as shown by arrow K. The ignition by spark plug 10 causes the flame to propagate rapidly within the depress 22. With a piston started down movement, uncombusted gases are withdrawn into area S, T together with flame to combust uncombusted HC, CO.
