Abstract
Provided is a combustion chamber applied in a gas engine including: a main combustion chamber including, at a central portion of its ceiling, an auxiliary combustion chamber; and a piston. A peripheral portion of a top surface of the piston is a flat surface. A raised portion, 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 being joined to the flat surface of the peripheral portion via a curved surface. When the piston is positioned at a top dead center, nozzle holes of the auxiliary combustion chamber jet out flame jets to a portion at which the raised portion of the top surface of the piston and the flat surface of the peripheral portion of the top surface of the piston are joined together.
