A combustion chamber system is described for an overhead valve type kerosine internal combustion engine, comprising: a cylinder head; a piston slidable in a cylinder; a main combustion chamber defined by a lower surface of a cylinder head and an upper surface of the piston; an auxiliary combustion chamber defined within the cylinder head and spaced from the main combustion chamber by a partition; a fuel feeding means for feeding an air-fuel mixture of a theoretical or richer fuel ratio to the main combustion chamber; a suction port and an exhaust port adapted to be opened and closed by suction and exhaust valves, respectively; an ignition plug provided to have an electrode thereof exposed to the auxiliary combustion chamber; and two communication holes formed in the partition to provide communication between the main and auxiliary combustion chambers, wherein respective open ends of the communication holes located on the side of the main combustion chamber are pointed to parts of an upper surface of the piston positioned near a top dead center thereof. The parts are located below the suction and exhaust valves, respectively, and wherein the auxiliary combustion chamber is defined by a wall surface of a bottomed bore formed on one side of the cylinder head and a stop plug for blocking an open end of the bottomed bore, and the electrode of the ignition plug is located in the auxiliary combustion chamber in close proximity to open ends of the communication holes in the partition walls of the auxiliary combustion chamber.
