Definitions

  • ABSTRACT [30] F i A li i p i i D
  • attaching means connecting said cylinder head [52] us CL 123/52 M 123/4169 123/41] to said cylinder block, said cylinder including a com- 123/193 123/195 181/33 bustion chamber, intake and exhaust ports communi- 51 1m.
  • This invention relates to an internal combustion engine comprising at least two housing parts such as a cylinder head and a cylinder block connected together by means of attaching elements, one of which housing parts has intake or exhaust ports leading to the combustion chamber, and a pipe which may be either an intake or exhaust pipe connected to the ports by a connection means.
  • the object of the invention is achieved by forming the pipe and the connecting means leading to the ports of at least two molded elements, which elements are held on the engine in the required operational position with the aid of the attaching-means that connects the two housing elements, e.g., the cylinder head and cylinder block.
  • the arrangement is made in such a way that at least one of the molded elements constituting the pipe is clamped down firmly with its flat part between the two housing parts.
  • each molded element consists of sheetmetal and is produced by a suitable forming process.
  • At least one opening is advantageously provided in the section'of the molded element projecting beyond the periphery of the housing element for the passage and/or support of a machine element seated in the housing part, as, for example, an injection nozzle.
  • FIG. 1 is a perspective view in partial section of two cylinder heads provided with an added intake pipe
  • FIG. 2 is a top view of FIG. 1, and
  • FIGS. 3 and 4 are two cross-sections through the pipe and its attachment taken along line IIl-III and IV-IV, respectively, of FIG. 2.
  • a two cylinder, aircooled internal combustion engine of known construction is shown.
  • the cylinder heads 10 and 12 which lie individually beside one another, are connected firmly by means of attaching screws 14 to a cylinder block 13 containing two perpendicular cylinders (not shown in detail).
  • input and output valves (not illustrated) are housed, which valves are driven by means of rocker arms, swivelably mounted in an upper part 16 or 18 of each cylinder head on both sides of a peg 20.
  • the drive of the rocker arms is accomplished each time by an assigned push rod 22 which is driven up and down by the control gearing of the engine. Every upper part has been attached to the assigned cylinder head by way of screws 28 and has been closed by means of a lid 24 or 26.
  • connection 10a with opening 10b also exists in the cylinder head 10. Both intake parts 10b and 12b are connected with an intake pipe by way of connection means, which pipe is formed and disposed in the manner described in the following paragraphs.
  • the intake pipe is made up of two thin-walled molded elements 30 and 32, which are punched from sheetmetal and formed for example in the cupping process.
  • the flat section 30a of element 30 in its built-in state covers up the upper front sides of both cylinder heads 10 and 12 and is tightened to block 13 by means of attaching screws 14 during attachment of cylinders heads l0, 12 to the block.
  • the upper parts 16, 18 are then placed onto section 300 and tightened by way of screws 28 to the cylinder heads.
  • a part of the edge of element 30 is bent upward and formed into a half pipe 30b.
  • the other element 32 is attached to element 30 at 32a by means of screws 14a. It is clear that in both elements 30, 32 suitable passages are provided for appropriate attaching screws. Details regarding this however have not been shown.
  • a section of element 32 which likewise has been pulled upwards, constitutes the other half pipe 32b and in addition contains two salient portions 320 which constitute the connecting channels from pipe 30b, 32b to the ports 10b, 12b. Air entering lateral ports A or B of the pipe consequently can flow through the two channels 32c, the intake connections 10a, 12a and hence into the combustion chambers.
  • this projecting section 30a or pipe element 30 functions as a cooling conductive plate for the cooling air, which flows through the cooling ribs lr, l2r and the cooling channels k, 12k disposed inside and outside the cylinder heads, as becomes particularly clear from FIG. 3.
  • the molded elements are provided in a suitable manner with continuous or supporting openings for engine elements, such as injection nozzles 34 and protective casings 22a of the push rods.
  • an internal combustion engine having at least one cylinder defined by a cylinder head and a cylinder block, attaching means connecting said cylinder head to said cylinder block, said cylinder including a combustion chamber, intake and exhaust ports communicating with said combustion chamber and a connection means connecting said ports to a pipe
  • the improvement which comprises forming said pipe and connection means of at least two molded elements produced from multilayered sheet metal which are held on the engine in the required operational position by the attaching means connecting together said cylinder heads to said cylinder block, at least one of the molded elements being clamped firmly between the cylinder head and cylinder block, said clamped molded element projecting beyond the periphery of said connected cylinder head and cylinder block, the section of the molded element projecting beyond the periphery of the cylinder head and cylinder block serving as a screening damping agent for the noises radiating from the engine.
