Description

Opfindelsen vedrører en cylinderkappe til en totaktsforbrændingsmotor i henhold til kravets indledning.The invention relates to a cylinder jacket for a two-stroke internal combustion engine according to the preamble of the claim.

Cylinderkapper til en, eller cylinderblokke til flere cylindre i en totakts-forbrændingsmotor, især til en lang-somtgående skibsdieselmotor, har hidtil været medinddraget i kølesystemet til køling af cylinderforinger og cylinder-10 blokke og bliver således gennemstrømmet af relativt varmt kølevand, som har temperaturer på 70-80°C, ved såkaldt "varmtvandskøling" endog 100-120°C. Den skylleluft, som er "oplagret" i cylinderkappens nederste del, har derimod en temperatur på 40-50°C. Disse temperaturforskelle kan føre 15 til, at cylinderkappen deformeres, således at der opstår flugtningsfejl mellem motorhuset og arbejdscylinderen eller arbej dscylindrene.Cylinder caps for one, or multi-cylinder cylinder blocks in a two-stroke internal combustion engine, especially for a long-range marine diesel engine, have heretofore been included in the cooling system for the cooling of cylinder liners and cylinder blocks and are thus flowed through relatively hot cooling water having temperatures. at 70-80 ° C, by so-called "hot water cooling" even 100-120 ° C. The flushing air which is "stored" in the lower part of the cylinder cover, on the other hand, has a temperature of 40-50 ° C. These temperature differences can cause the cylinder sheath to deform, resulting in failure to escape between the motor housing and the working cylinder or working cylinders.

Opfindelsen har til formål at hindre en deformation og 20 vridning af cylinderkappen og det dermed forbundne modtagesystem for skylleluften. Denne opgave løses ifølge opfindelsen med en cylinderkappe med de i kravet beskrevne egenskaber.The invention has for its object to prevent a deformation and twisting of the cylinder sheath and the associated receiving system for the rinsing air. This task is solved according to the invention with a cylinder sheath having the characteristics described in the claim.

25 Da den nye cylinderkappe ikke længere påvirkes af kølevand, optræder de ovenfor beskrevne temperaturforskelle ikke, og følgelig undgås de ovenfor nævnte deformationer. En yderligere fordel ved opfindelsen består i, at komplicerede kølekanaler og tætningssteder på og i cylinderkappen bortfal-30 der, og at skylleluftkammeret i cylinderkappen er forstørret, således at der kan spares et tilsvarende volumen i modtagesystemet.25 As the new cylinder jacket is no longer affected by cooling water, the temperature differences described above do not occur and consequently the aforementioned deformations are avoided. A further advantage of the invention consists in the fact that complicated cooling ducts and sealing places on and in the cylinder casing are omitted and that the purge air chamber in the cylinder casing is enlarged so that a corresponding volume can be saved in the receiving system.

Opfindelsen beskrives i det følgende på grundlag af et ud-35 førelseseksempel som vist på tegningen, hvis eneste figur viser den nye cylinderkappe og den med kappen forbundne 2The invention is described below on the basis of an embodiment as shown in the drawing, the only figure of which shows the new cylinder sheath and the sheath associated with the sheath.
