Abstract: PURPOSE: To avoid adverse affections caused by knocking, by providing an ignition plug on the upstream side of a guiding wall but in the vicinity of said plug and by forming a flame guiding hole at the downstream of said plug so that the propagation of the flame can be accelerated.  
     CONSTITUTION: Intake air from an intake port 3 is admitting along a guiding wall 6 in a combustion chamber 2 to produce swirl in the arrow direction. When an air fuel mixture is ignited by an ignition plug 5, the flame produced in the combustion chamber 2 passes through a guiding groove 7 formed on the downstream side of the guiding wall 6 toward the downstream of the guiding groove 7. Because of compression swirl created by the guiding wall 6, there is no possibility that the propagation of the flame is blocked, and the small volume of mixture, i.e., a part of mixture on the guiding wall 6 is burnt at the initial stage of combustion, thereby being free from knocking which tends to occur when combustion has been completed.
