ABSTRACT:
An internal combustion engine comprising a main combustion chamber and an auxiliary combustion chamber are interconnected to each other via at least one connecting passage. The auxiliary combustion chamber and the connecting passage are formed in an auxiliary chamber component which is press-fitted into the recess formed in the cylinder head. The spark plug is located in the connecting passage. The inner wall of the connecting passage is covered by a heat insulation member which is made of a heat resistable material such as Invar for ensuring the stable growth and the non-extinguishment of the flame of combustible mixture ignited by the spark plug.
