エンジンの燃焼室。 In a combustion chamber of a diesel engine in which a swirl chamber is formed by inserting a swirl chamber cap into a recess formed on the lower surface of the cylinder head, a groove extending in the circumferential direction is provided on the outer circumferential surface of the swirl chamber cap to form a groove on the inner circumference of the cylinder head recess. An annular space is formed between the cylinder head and the vortex chamber, and a spacer is provided in the annular space, while leaving a space, the spacer is made of a material having a higher coefficient of thermal expansion than the cylinder head and the swirl chamber mouthpiece. combustion chamber of a diesel engine.
