Definitions
- the temperature of the cylindrical inner sur ⁇ face of the liner must be controlled within a comparat- ively narrow interval which is restricted downwards by the wish to prevent sulphuric acid from condensing on the inner surface, and upwards with the view of impeding high-temperature damages to the structural material of the liner.
- the con ⁇ densation of sulphuric acid resulting in intense cor ⁇ rosive wear both of the inner surface of the liner and of the piston proper may be avoided, if the temperature of the inner surface of the liner is kept at 200 to 230°C in the area adjacent to the upper piston ring when the piston is in its top dead centre position.
- the arrows A in Fig. 3 illustrate how the heat in a known embodiment of a cooling channel during the working of the engine flows from the inner surface of the liner to the annular space surrounding the tube. It will appear that the heat has a comparatively short distance of travel, thereby offering a high temperature gradient and thus a strong cooling. If a smaller cooling effect of the cooling channels is desired with one and the same cylinder liner, the cooling channels may instead be provided with a guide member according to the invention.

Abstract
Chemise de cylindre (1, 1') pour moteurs à combustion interne refroidis par l'eau, possédant une pluralité de canaux de refroidissement sous forme de perçages borgnes allongés (8, 8') s'étendant vers le haut à partir d'une chambre d'alimentation en liquide de refroidissement (6; 6'), et reliés à une chambre de décharge de liquide de refroidissement (7; 7'). Un élément de guidage (21; 38) est monté à l'intérieur du canal et sert à éviter que l'écoulement d'eau ne touche et refroidisse une section (32; 40) de la surface du canal qui est orientée vers la chambre de combustion, de sorte que le gradient thermique sur la chemise s'amenuise, ce qui entraîne une diminution de l'action refroidissante.Cylinder liner (1, 1 ') for water-cooled internal combustion engines having a plurality of cooling channels in the form of elongated blind bores (8, 8') extending upwardly from a coolant supply chamber (6; 6 '), and connected to a coolant discharge chamber (7; 7'). A guide member (21; 38) is mounted inside the channel and serves to prevent the flow of water from touching and cooling a section (32; 40) of the surface of the channel which is oriented towards the chamber combustion, so that the thermal gradient on the jacket is reduced, which results in a decrease in the cooling action.
