特徴とするセラミツクピストン。 Attach a ceramic cap to the top of the piston,
In a ceramic piston forming a combustion chamber, a concave part that widens toward the end is formed on the surface of the ceramic cap that contacts the piston, and a concave part is formed between the ceramic cap and the piston to press the contact surface toward the piston. A ceramic piston, characterized in that a bolt is installed, one end of which is inserted into the recess, and the insertion portion of the bolt is made of an irreversible shape memory alloy that changes its shape to fit tightly into the recess at a predetermined temperature.
