  • the present invention relates to water-cooled reciprocable piston engines in which the cylinder head together with the cylinder forms one single integral piece and is inserted into a cylinder mantle housing.
  • internal combustion engines for purposes of obtaining maximum outputs, supercharging is increasingly employed.
  • weak areas form at various structural elements which reduce the function and life span of the parts; in particular the seal between the cylinder head and the cylinder is affected.
  • the cylinder head is sometimes made one piece with the cylinder.
  • water-cooled engines it is preferred to design the cylinder mantle housing as a separate part, because in this way simpler cast pieces are obtained for the cylinder with the cylinder head and for the cylinder mantle housing.
  • a water-cooled internal combustion engine to design the cylinder head with the cylinder as a single integral piece and to insert the same into a cylinder mantle housing which simultaneously forms one part with the crank-casing.
  • FIG. I is a cross section through a water cooled reciprocable piston internal combustion engine of the V- type.
  • FIG. 2 is a section taken along the line Il-ll of FIG. 1.
  • the internal combustion engine according to the present invention is characterized primarily in that in the cylinder mantle housing for each cylinder there is provided a lateral opening which is adapted to be closed and which has a height greater than the width of the range of the piston rings, while the position of said opening extends from the lower portion of the piston ring range toward the cylinder foot portion, while said piston is in its upper dead center position.
  • FIG. 1 shows a watercooled reciprocable piston internal combustion engine in which the cylinder head 1 and the cylinder 2 form a single integral piece.
  • the cylinder unit I, 2 is, as shown more clearly in the left-hand cylinder row, inserted into a water conducting cylinder mantle housing 3.
  • the cylinder 2 is illustrated during the phase of pushing the cylinder over a piston 4 with piston rings 5.
  • a clamping band 7 is placed around the annular range. The band 7 is compressed, by means of pliers 9, through the opening 8 in the wall of the cylinder mantle housing 3.
  • a water-cooled reciprocable piston engine which includes in combination a cylinder head, a cylinder forming one single integral piece with said cylinder head, a piston skirt with a free end and being provided with piston rings and being reciprocable in said cylinder, a cylinder mantle housing extending upwardly as far as to said cylinder head and surrounding said cylinder head to form a water chamber therewith and having a laterally closable opening therein freely accessible for piston assembly in said cylinder and which in the axial direction of said piston extends over a length greater than the axial extension of the range of said piston rings and in the upper dead center position of said piston extends from that end of said piston ring range which is closest to the free end of said piston skirt to approximately said free end of said piston skirt.
