    A multi-cylinder internal combustion engine has flangeless wet cylinder liners to reduce the size of the engine. Each cylinder liner has a shoulder near its crankcase end for sealing a coolant space around the liner and for compression against a seat of an engine block with an individual cylinder head at its opposite, flangeless cylinder head end. Near the cylinder head ends, the liners have side sealing lands cooperative with sealing lands on a web of the engine block without affixation thereto for sealing the adjacent end of the coolant space, the web being thin because it does not support the cylinder head to reduce further the engine size.

    2, The engine according to Claim 1, which is due to the fact that the sealing along the cylinder liner is provided with at least one concentric annular groove and 0 shaped
    the ring is set in the last one
    3, the engine according to Clause G., which is based on the fact that the lower part of the cylinder liner in the -zone of the support collar is provided with 0-shaped rings.
    4, The engine of claim 1, 1, about 1 t and the fact that.
    The invention relates to mechanical engineering, in particular, to engine construction, and can be used in multi-cylinder internal combustion engines with wet cylinder liners and separate cylinder heads.
     The purpose of the invention is to reduce the size of the engine,
    FIG. 1 shows a portion of the crankcase, a longitudinal section; in FIG. 2, node I in FIG. 1j in FIG. 3, section A-A in FIG. 1; FIG. 4 is a section BB in FIG. 3 (in the zone of the cooling cavity between the cylinder); in fig. 5 is a section b-B in FIG. 3 (tidal for cutting cylinder head bolts)
    The engine contains separate cylinder heads 1, crankcase 2, wet cylinders of 3 cylinders with a lower support collar 4, which rests on the corresponding section 5 of the crankcase 2, with the help of heads I of the sleeves 35 having a slight rise under the plane of abutment, they are pressed to the protrusions 5 and are clamped in the crankcase 2 with the formation of compacted cooling cavities 6 between them. s cylinders and forming with the latter for a seal 8 provided with at least one 0-ring 9 kruglo215628
    the block-crankcase wall is provided with a channel connected to the upper part of the cooling cavity by means of an additional cooling channel inclined to the partition of the block-crankcase,
    5. Engine pop, 1, characterized in that cylinder liners are provided with annular grooves located under the sealing ring and connected to the cooling cavity,
    section between the partition 7 and the sleeve 3, in the area of the sealing box 8, the sleeve 3 is provided with annular grooves 10 in which the ring 9 is installed. As a result of this sealing of the cylinder liners 3, separate heads 1 can be used through the gap 1I between the heads 1 "
    A sealing ring 12 can also be installed in the area of the lower support collar 4 to prevent corrosion of the liner bearing surface. Two more O-rings 13 are also provided, which are located under the support collar 4 and serve to seal the oil space 14,
    The side wall of the crankcase is provided with a channel 15 connected to the upper part of the cooling cavity 6 by means of an inclined channel 16 passing under the tides 17 under the threads of the bolts of the heads 1. connected to the cooling cavity and the blowing holes 19,
    The thread of the bolts 20 of the cylinder heads 1 is located above the collar 4, as a result of which the tensile stresses of the block are converted into compressive stresses,
    When the engine is running, cooling means from channel 15 are inclined
    The channel 16 is forcibly supplied to the upper cup of the cooling cavity 6, cooling the cylinder liner 3.
    The proposed solution allows, while maintaining the size of the engine, to significantly increase ra12156284
    The barrel volume of the cylinders due to the increase in their diameters while maintaining the distance between them. In addition, the sealing of the cooling cavities 5 is improved by using separate cylinder heads.
