Definitions

  • the invention relates to a cylinder head gasket, in particular a at least substantially metallic cylinder head gasket, with which the Influencing coolant flow within a reciprocating internal combustion engine leaves, which has several combustion chambers in a row (it can are a so-called in-line engine, but also one so-called V-engine or another engine with several so-called Cylinder banks).
  • the Coolant then flows substantially past the cylinder bank into the Area of the other narrow or front side of the engine; in this area indicates the cylinder head gasket clamped between engine block and cylinder head Coolant passage openings through which the coolant in the cylinder head is passed - because the coolant pump of the engine upstream of the engine block is prevailing in the coolant cavities of the engine block, a higher coolant pressure than in the cylinder head. Derived the coolant is at the cylinder head, in the area of those Front side of the engine, where the coolant flow is introduced into the engine block becomes. Looking at the in a plan view about a narrow rectangle corresponding cylinder head, so are located on one of its longitudinal side the intake ports and at its other, opposite longitudinal side of the Exhaust channels.
  • the invention was based on the object, a cylinder head gasket create, at least defuse the described problems, if not let eliminate.
  • the invention is based on a cylinder head gasket for a motor, in the cylinder head gasket adjacent to the engine block at least one of Coolant perfused first coolant cavity is formed, wherein the gasket having a cylinder head gasket at least one from the sealing plate protruding flow guide for the coolant is provided and the sealing plate has coolant passage openings, over which the at least one first coolant cavity with at least a second, formed in the cylinder head of the engine coolant cavity is connectable.
  • such a cylinder head gasket is designed so that the at least one flow guide to a coolant passage opening so connects and is designed such that the flow guide forms a flow path with the coolant passage opening and for engaging at least one of the first and second coolant cavities and for generating a directed coolant jet preferably the cylinder head facing the outlet end of the flow path is designed.
  • the invention makes it possible to the kinetic energy of the engine block in the neighborhood of the Use cylinder head gasket existing coolant flow and / or to use a designed in the manner of a nozzle flow guide to in the cylinder head entering coolant streams with not insignificant To generate kinetic energy, so that in the cylinder head in the neighborhood the cylinder head gasket prevailing coolant flow in the desired Significantly deflect and / or swirl one's way (thereby eliminate dead zones in the cooling water flow) or selected ones Even places targeted to the cylinder head with partial coolant streams to let.
  • each cylinder head gasket for a specific Engine is constructed, d. H. the developer of the seal is the Engine design already before; therefore it is permissible in the definition of a cylinder head gasket invention relating to features of the engine block and / or the cylinder head.

But these flow guide serve exclusively for this (and for something else they are not even in the Lü), the coolant flow within this formed in the engine block Redirect coolant cavities and selected locations of the engine block to judge; Alternatively, the same measure for the trained in the cylinder head Coolant cavities proposed (see Sp. 6, lines 43-46 of EP-0 868 603-B1).
  • EP-0 868 603-B1 points away from the present invention, as the Flow guide arranged at locations of the cylinder head gasket should be at which the coolant does not pass into the cylinder head (see SP 6, lines 13-16 of EP-0 868 603-B1, that is to say, for example, in FIG The openings shown in this document are intended to be in such places those on the engine block side and / or the cylinder head side of the Cylinder head gasket no coolant cavity is located). Otherwise disclosed EP-0 868 603-B1 consequently coolant passages of the Cylinder head gasket only in one narrow side end region of the gasket plate (See the coolant passage openings 8 in Figures 2 to 4b and 6).
  • the cylinder head gasket according to the invention Engines in which the at least one first coolant cavity (im Engine block) is flowed through by the coolant such that at least in one Area of this coolant cavity is a major flow component the coolant flow is approximately parallel to the seal plate, because then, to achieve an effective directional coolant jet in addition to the pressure difference between the two sides of the cylinder head gasket also the kinetic energy of this main flow component be used in that the flow guide for intervention is formed in the first coolant cavity and designed in such a way that it is built-in cylinder head gasket such a baffle and deflection for the main flow component forms that in the Flow guide associated coolant passage opening a transverse to Seal plate aligned coolant flow occurs.
  • a directional coolant jet with a relatively high Flow rate according to the invention also generated by a kind of nozzle become;
  • a cylinder head gasket according to the invention is so formed, that the flow guide for engaging in the second Coolant cavity (in the cylinder head) and formed on the outlet side (Cylinder head side) End of the flow path with a nozzle for generating a directed coolant jet in the second coolant cavity provided is.
