A peripheral portion of a top surface of the piston 5 is a flat surface 15. A raised portion 17, which has a curved surface and which is a solid of revolution, is formed at a central portion of the top surface, the raised portion 17 being joined to the flat surface 15 of the peripheral portion via a curved surface. When the piston 5 is positioned at a top dead center, nozzle holes 19 of the auxiliary combustion chamber 13 jet out flame jets 25 to a portion at which the raised portion 17 of the top surface of the piston and the flat surface 15 of the peripheral portion of the top surface of the piston are joined together.",
