TH32130B - Pistons for internal combustion engines - Google Patents

Abstract

DC60 (27/09/54) The purpose of this invention is The arrangement of pistons for internal combustion engines with The ability to provide sufficient assurance about the performance of oil film formation on cylinder internal surface and minimizing piston sliding resistance Pistons for internal combustion engines are characterized by a number of indentations 25 made on the male section 24 in such a way that they are aligned in the axial direction and in the circumferential direction of the piston 20 and that they have tracks 26 along the circumferential direction of the piston. Piston 20 is made on the male section of piston 20 and is the gap between the opposite edge sections of the dent side-by-side in the axial direction of the piston 20, larger than the track width. The purpose of this invention is The arrangement of pistons for internal combustion engines with The ability to provide sufficient assurance about the performance of oil film formation on cylinder internal surface and minimizing piston sliding resistance Pistons for internal combustion engines are characterized by a large number of indentations (25) made on the male section (24) in such a way that they are aligned in the axial direction and in the circumferential direction of the piston (20) and that they are notch ( 26) along the circumferential direction of the piston (20) is made on the male section of the piston (20) and is the gap between the opposite edge sections of the dent side-by-side in the axial direction of the piston (20). The size is larger than the width of the track.

Claims (2)

1. Pistons for an internal combustion engine in which the pistons are mounted to slide. Glides are possible in the cylinders of the internal combustion engine, characterized by a number of dimple dents made on the skirt portion which is the piston slippage that supports the Such cylinder A certain amount of such indentation will be made in a staggered configuration in the axial direction. And in the circumferential direction of the piston and a single work trace, the circumferential direction is made on the male part of the piston. And the gap between the straight edges The cross of the adjacent dent in the axial direction of such piston is set to a larger value. Width of the track And is smaller than the diameter of the dent The edges of the indentations that are adjacent to each other in the peripheral direction of the pistons are made in The overlap in the circumference of the piston. 2. The piston for the internal combustion engine mounting according to claim 1, characterized by that the cylinder is positioned almost in the horizontal direction, the male portion of the piston is aligned. To the vertical direction, and the indentation was made on the hem at the top
