ABSTRACT:
A two-cylinder two-stroke internal combustion engine is provided with insed cylinder liners carrying separate thin-walled cooling jackets. In the area of the intake and exhaust ports the walls of the liners are thickened in order to improve the directing of the inflowing charge and to facilitate a leak-proof attachment of the cooling jackets.
The areas of the two cylinder liners facing each other are not thickened nor do they have any ports; they are only provided with a collar continuing the upper edge of the thickened portion and serving for the leak-proof attachment of the cooling jacket, such that the space between the cylinders lying below this collar may be utilized for the exchange of fresh charge between the two longitudinal sides of the engine, without the need for an increase of the distance between the cylinders.
