Definitions

  • the invention relates to a cylinder head for a water-cooled multi-cylinder internal combustion engine according to the features of the preamble of claim 1.
  • the cooling circuit is shown and described for a multi-cylinder internal combustion engine in which about 2/3 of the coolant flow circulated to the engine cooling circulated through the cylinder head housing for needs-based coolant flow distribution. So that all cylinder head units are cooled uniformly, it is further provided that the cylinder head housing is traversed transversely by the coolant with respect to the longitudinal axis of the cylinder bank. These are measures to be able to dissipate the resulting during combustion high jet heat from the cylinder head housing. From the DE 199 43 001 C1 It is also known to cool a hot spot in the cylinder head by means of an additional channel leading to the hot spot. Furthermore, from the DE 35 16 453 C2 it is known to direct the flow of cooling liquid in the direction of a spark plug dome by means of ribs arranged in the cylinder head.
  • the object of the invention is to provide further measures to effectively and effectively cool the high-temperature-loaded areas of the cylinder head.
  • a temperature load in the cylinder head adapted cooling is achieved within the cylinder head of a multi-cylinder internal combustion engine, in which a main coolant flow between the two exhaust valves of the valve motor is guided in the direction of the spark plug, while the edge zones of the cylinder head cooling chambers are supplied by secondary cooling flows.
  • the coolant is passed in an advantageous manner in the region of the high temperature loaded spark plug dome. Characterized in that the cross sections of the two guide ribs are formed differently, a cross flow is generated behind the guide ribs, which counteracts the formation of so-called. Totwasser Theen and contributes to the fact that even in the intake valves sufficient coolant supply is present.
  • the diameter of the outflow openings is of different sizes.
  • a cooling channel is additionally provided on the inflow side in the cylinder head, which leads coolant directly to the hot spot.
  • the geometry of a water jacket, hereinafter referred to as the cylinder head cooling chamber 2, a cylinder for a multi-cylinder internal combustion engine, as for example in the DE 100 21 525 A1 is described.
  • the cylinder head cooling space 2 of each cylinder is supplied with cooling water via two inlet openings 4 and 6 provided in the cylinder head housing.
  • two outflow openings 8 and 10 are provided, via which the coolant heated by the cylinder head flows to the suction side of the water pump, not shown, of the internal combustion engine.
  • a centrally provided in the cylinder head cooling chamber 2 opening 16 forms the receptacle or the dome for the spark plug of the respective cylinder.
  • a centrally provided in the cylinder head cooling chamber 2 opening 16 forms the receptacle or the dome for the spark plug of the respective cylinder.
  • two rib-shaped recesses 18 and 20 are provided, which are formed in the cylinder head housing as positive to two guide ribs 18 'and 20'.
  • the cross sections of the two guide ribs 18 'and 20' are formed differently strong; the function of this embodiment will be explained later in more detail.
  • a recess 22 for the two intake valves of the cylinder head follows behind the two recesses 18, 20 and the central opening 16.
  • the inflow side of the cylinder head cooling chamber 2 is formed so that a main cooling flow Q 2 and Q 3 between the two exhaust valves (recess 12, 14) in the direction of the spark plug center (central opening 16) is guided via the inlet openings 4 and 6, while in the left and the right edge region of the cylinder head cooling chamber 2, a secondary cooling flow Q 1 and Q 4 is formed, which is guided over the two outflow openings 4 and 6 on the outside of the two recesses 24 and 26 in the direction of the ribs 18 'and 20' along.
  • the cooling streams Q 2 and Q 3 are, as shown by the arrows, due to the Zündkerzendomes in the direction of the guide ribs 18 'and 20' directed where they meet with the cooling streams Q1 and Q4 together.
  • the fact that the cross section of the guide rib 18 'with respect to the guide rib 20' is smaller and that the diameter of the discharge opening 8 is greater than the diameter of the discharge opening 10, in the region of the inlet valves (see recess 22) generates a transverse flow Q transverse to an optimal cooling of the cylinder head housing also contributes in this area, thus preventing the formation of so-called dead water areas.
  • coolant flowing through the cooling channel Q 5 directs coolant directly to a hot spot in the cylinder head housing, which is formed in the wall region of the combustion chamber at the level of the spark plug dome, the opening or the thread for receiving the spark plug encloses.
