ABSTRACT:
Disclosed is an internal combustion engine comprising a main combustion chamber and an auxiliary combustion chamber interconnected by two connecting passages with each other. A raised portion having a flat lower end face is formed on the inner wall of the cylinder head. A squish area is formed between the flat lower end face of the raised portion and the flat top surface of the piston when the piston reaches the top dead center. The spark gap of the spark plug is located in a first one of the connecting passages or in the auxiliary combustion chamber at a position near the first connecting passage. The first connecting passage is so arranged that the squish flow passes through in front of the opening of the first connecting passage for decelerating the combustible mixture stream forced into the auxiliary combustion chamber via the first connecting passage at the time of the compression stroke. The second connecting passage is arranged at a position wherein the squish flow does not obstruct the combustible mixture stream forced into the auxiliary combustion chamber via the second connecting passage at the time of the compression stroke.
