Abstract

PURPOSE:To prevent the occurance of cracks caused by heat load by installing a metal ring of larger elastic modulus than that of the piston, at outside of the combustion chamber formed at the top of the piston. CONSTITUTION:Combustion chamber 10 with inlet 12 at the upper part is formed at the top 13 of the piston P of a diesel engine, and metal ring 14 of larger elastic modulus than that of the piston is fixed axially on the outer circle of the side wall of said combustion chamber 10.
