Abstract:
A spark ignition internal combustion engine comprising:a sub-combustion chamber communicated with a main combustion chamber;a gas mixture injecting device for directly and intermittently injecting gas mixture into said sub-combustion chamber; andan igniting device arranged in said sub-combustion chamber,wherein said sub-combustion chamber is communicated with said main combustion chamber eccentrically displaced from an extended line of an injecting direction of said gas mixture injecting device, andwherein said sub-combustion chamber is formed in a diverging shape in a slant non-symmetrical angle toward said main combustion chamber along an injection extended line of said fuel injecting device, a striking wall is projected from a downstream edge of a gradual slant side surface of said sub-combustion chamber gradually slanted against the injection extended line of said fuel injecting device along a downstream edge of a steep slant side surface of said sub-combustion chamber inclined in a steep state, and an igniting means is arranged at said steep side surface of the sub-combustion chamber.
