ことを特徴とするトロイダル形燃焼室をもつピストン。In a type in which the combustion chamber 1 is provided eccentrically, the radial direction dimension R and the depth direction dimension of the rib (squish rib) provided at the peripheral edge of the opening of the combustion chamber 1 are such that the squish is stronger than the side 3 where the squish is stronger. A piston with a toroidal combustion chamber, characterized in that both increase toward the weak side 4, and the occurrence of overheating due to an increase in the radial dimension R is avoided by increasing the depth dimension.
