Abstract
PURPOSE: To provide a combustion chamber of internal combustion engine, in which a multiplicity of recesses are formed in the top surface of piston or inner wall surface of cylinder head where a squish area is defined, so as to give turbulence to uncombusted mixture that is drawn into the squish area when piston moves downward, whereby it is enabled to increase combustion speed.
CONSTITUTION: A multiplicity of recesses 12 are formed in the top surface 2a of piston 2 and flat bottom wall surface 9 of projection 8 forming a first squish area A, and similarly, a multiplcity of recesses 12 are formed also in inner wall surface 3a of cylinder head 3 forming a second squish area B together with projection 10. With such an arrangement, when piston 2 comes to the top dead point in compression cycle, squish flow with turbulence caused by recesses 12 issues from both of the first and the second squish areas A, B into combustion chamber 4 respectively in the direction shown by arrows C and D. Resultantly, swirl around a horizontal axis is developed in combutsion chamber 4 by the squish flow C, D, as shown by arrow W in the drawing, so that combustion speed can be increased considerably.
