Abstract:
(EN) This piston is provided with a piston body and a film. The film has a film body and a film thickness measurement recess. The film thickness measurement recess is opened toward a combustion chamber, and has a bottom section, an opening edge section, and a peripheral wall section lying between the bottom section and the opening edge section. At least some portions of the opening edge section and of the peripheral wall section are composed of the film body. At least a portion of the bottom section has a film thickness measurement reference surface where the film body is absent.
(FR) L'invention concerne un piston pourvu d'un corps de piston et d'un film. Le film présente un corps de film et un évidement de mesure d'épaisseur de film. L'évidement de mesure d'épaisseur de film est ouvert vers une chambre de combustion, et comporte une section inférieure, une section bord d'ouverture, et une section paroi périphérique située entre la section inférieure et la section bord d'ouverture. Au moins certaines parties de la section bord d'ouverture et de la section paroi périphérique sont composées du corps de film. Au moins une partie de la section inférieure a une surface de référence de mesure d'épaisseur de film au niveau de laquelle le corps de film est absent.
(JA) ピストンは、ピストン本体部と膜を備える。膜は、膜本体部及び膜厚測定用凹部を有する。膜厚測定用凹部は、燃焼室に向かって開口しており、底部、開口縁部、及び底部と開口縁部との間の周壁部を有する。開口縁部及び周壁部の少なくとも一部は膜本体部からなる。底部は、少なくとも一部に膜本体部が存在しない膜厚測定用基準面を有する。
