A method for adjusting the volume of the combustion chamber of an engine with high accuracy is provided. A cylinder head (200) of an engine includes a recess (204) constituting part of the combustion chamber of the engine, and a mating surface (202) for a cylinder block. The method for adjusting the volume of the combustion chamber includes measuring a plurality of portions of the surface of the recess (204) and a plurality of portions of the mating surface (202) by using a displacement meter, calculating differences between the respective measurement values of the mating surface (202), and the design shape of the mating surface (202) in a state in which the design shape of the surface of the recess (204) is fitted with respect to the respective measurement values of the recess (204), and deciding the cutting amount of the mating surface (202) based on the calculated differences and cutting the mating surface (202) by the decided cutting amount. |
