Abstract: 본발명의연소실(2)은내벽면을이루어연소공간을형성하는프로파일면(5)에연소공간의중앙을향해튀어나온돌출부(7)를이용해그 위쪽으로연소공간의상부를형성하고그 아래쪽으로연소공간의하부를형성함으로써, 프로파일면(5)을향해분사된분무연료가돌출부(7)를기준으로연소공간의상부로퍼져나가는흐름과연소공간의하부로퍼져나가는흐름으로이원화될수 있어혼합기형성율을크게높여주고, 이와더불어동시에분사된 2개이상의분무연료가중첩을일으키지않아연비저하와유해배출가스양을증가시키는불완전연소를방지할수 있는특징을갖는다.

Abstract: PURPOSE: A diesel engine piston is provided to reduce incomplete combustion by preventing the overlap between two fuels that are adjacently sprayed. CONSTITUTION: A diesel engine piston includes a combustion chamber(2) protruding from an inner wall of a combustion space. The combustion chamber includes a profile surface(5) which distributes sprayed fuel to upper and lower parts from the protruding part of the inner wall. The combustion space comprises a flat bottom, and a pip(9) symmetrical to the center of a piston body is formed into a cone shape.

Abstract translation: 目的：提供柴油发动机活塞，以通过防止相邻喷射的两种燃料之间的重叠来减少不完全燃烧。 构成：柴油发动机活塞包括从燃烧空间的内壁突出的燃烧室（2）。 燃烧室包括：轮廓表面（5），其将喷射的燃料从内壁的突出部分分配到上部和下部。 燃烧空间包括平坦的底部，并且与活塞体的中心对称的喷嘴（9）形成为锥形。
