Definitions

  • the invention relates to a cylinder head for a Internal combustion engine with at least two cylinders with one bottom wall, which is an ignition surface for each of the cylinders, and a hollow interior that forms a cooling water jacket, and an internal combustion engine.
  • Heavy diesel engines usually have one Coolant jacket on what coolant in a cylinder head from one adjacent to the top dead center of a cylinder Area furthest away from a coolant outlet is, through the rest of the cylinder head over corresponding areas the remaining cylinder to the coolant outlet transported. The area of the cylinder that corresponds to the Coolant outlet is located closest is therefore hotter as the corresponding area of the cylinder, the farthest is removed from the coolant outlet.
  • US-A-4,291,650 shows a cylinder head with a Coolant chamber through a wall in a lower and an upper area is shared.
  • the wall is adjacent to each combustion chamber an opening that one Coolant exchange between the upper and lower areas enables.
  • a cooling water jacket with two levels Cooling of the cylinder head provided.
  • the lower one conductive cooling level allows the coolant from which Engine block to flow into the cylinder head to the ignition surface to cool only one cylinder.
  • the coolant flows from the conductive cooling level up to a transport level that has a cross-flow channel that the coolant to a Opening conducts without the coolant with the direct Cooling the ignition surface of another cylinder in contact is coming.
  • cooling level and the upper transport level Channel there is a between the cooling level and the upper transport level Channel provided.
  • This is preferably a annular channel that surrounds the injector sleeves.
  • access to the bore surfaces from outside of the cylinder head possible, so that the surface of the bore can be machined. Since the bore surface in the cylinder head and the injector sleeve surfaces machined, the size of the channel lies within manufacturing and not within Casting tolerances. This results in very little Flow variations from one cylinder to another, causing uniform cooling of the cylinders is brought about.
  • a cylinder head corresponding to the shown present invention and essentially with the Reference number 10 denotes.
  • the cylinder head 10 has one cast iron block 12, which with a plurality of Passages is poured in a known manner.
  • the passages include holes 14 for receiving screws, holes 16 for fuel supply devices or injectors, several Passages for intake and exhaust valves (in Figures 2 and 3 shown) as well as passageways that have a cooling water jacket form as will be described in more detail below.
  • a lower wall 20 forms the underside of the cylinder head 10, the area of top dead center of each cylinder forms and is referred to below as the ignition surface 18.
  • the Ignition surface 18 forms the top of the combustion chamber each Cylinder and is the area of the cylinder head 10 that the most cooling required.
  • the cooling water jacket of the Cylinder head 10 provides conductive cooling of the ignition surface 18th
  • the cylinder head 10 of the present invention is one Cooling jacket provided in two separate levels of the Cylinder head 10 is arranged.
  • a lower, senior The cooling level has a lower chamber 22, which is shown in FIGS and 2 is shown.
  • the lower chamber 22 is immediate arranged above the lower wall 20 of the cylinder head 10, the underside of which forms the ignition surface 18.
  • the lower chamber 22 is essentially as best seen in Figure 2 can be rectangular and has four in its four Corner areas coolant inlets 24, the coolant from the cooling water jacket of block 12.
  • the lower chamber 22 encloses the passage 26 for the inlet of air and the Passage 28 to exhaust gases.
  • a drive with two inlet and two outlet valves shown is easily perceived that the cylinder head 10th of the present invention on drives with more or less Valves can be used.
  • the branches 34 are closed by plugs (freeze plug) 48 closed.
  • the lower chamber 22 has branches 30 for one Coolant flow between passages 26 and 28 to the Center of the lower chamber 22 on the Injector sleeve 32 surrounds.
  • the injector sleeve 32 is fitted into the bores 16 and extends through the ignition surface 18.
  • a seal 35 is between the Injector sleeve 32 and the lower wall 20 molded, to leak coolant from the lower chamber 22 into the To prevent combustion chamber underneath.
  • An O-ring seal 47 seals the upper end of the nozzle sleeve 32 against the Block 12 onwards.
  • the coolant jacket also has an upper transport level on having a cross flow channel 36 and a connection area 38 has.
  • the transport area is with the lower one Cooling surface connected via an annular channel 40, the between the injector sleeve 32 and an inner surface 42 of the bore 16 is formed.
  • the cross flow channel 36 is in FIG. 3 shows and directs coolant to a reservoir 52 one end of the cylinder head 10.
  • the cross flow passage 36 is also provided with branches 54.
  • the branches 54 are formed by areas of the casting core, which the core in the Hold the mold. These branches are replaced by additional ones Sealing plug 56 closed.
  • Figure 3 also shows the air inlet and exhaust outlet passages 26, 28 through the Cylinder head 10, as well as the valve guides 64, 66 for the Intake and exhaust valves.
  • the reservoir 52 has one Bypass outlet 68 for coolant flow when cold Drive on by a thermostat, not shown is controlled in an upper opening 70 in the reservoir 52 (shown in Fig. 5) is attached. Another one Opening in the reservoir 52 is the Coolant outlet 72 for heated coolant that the Cylinder head 10 leaves and is also by means of a Thermostat controlled.
  • the reservoir 52 also has one Plug 74 on.
  • Coolant flows into the cylinder head 10 via the inlets 24 in the four corner areas of the lower chamber 22.
  • the coolant flows radially inward around the inlet and outlet passages 26, 28 to the center of the lower chamber 22 and to the annular channel 40. There the coolant rises to the Transport level where the coolant through the Connection area 38 reaches the cross-flow channel 36. As soon as it is in the cross-flow channel 36, the coolant to the coolant outlet 72 at the end of the cylinder head 10 headed.
  • the lower, directed coolant level of the coolant jacket has a lower cooling chamber 22 for each cylinder of the Multi-cylinder drive, the lower cooling chambers 22nd are arranged separately from each other.
  • An area of a lower one Cooling chamber 22 of an adjacent cylinder is shown in FIG. 2 shown.
  • the adjacent lower cooling chambers 22 are through separated a wall in the cast block 12. Coolant must from the lower cooling chamber 22 through the annular channel 40 flow to the upper transport level where the coolant passes through the cross flow channel 36 to the opening 72 (FIG. 5) at one end of the cylinder head 10 is passed.
  • Coolant from the ignition surface in a lower cooling chamber 22 has been heated, does not flow into another lower cooling chamber 22.
  • the firing surface 18 of each cylinder experiences the same degree on cooling, giving better control of the middle one Temperature in the lower cooling chamber 22 and the ignition surface 18 will be produced. There are fewer variations of the Temperatures between the ignition surfaces 18 of the various Cylinder on.
  • the size of the annular channels 40 will be within Machining tolerances controlled instead of casting tolerances, causing variations in the size of channels 40 between the Cylinders can be controlled more precisely.
  • the precise control of the Size of the annular channel 40 is possible in that the Channels 40 are arranged in the inlet openings while a External access for machining the Bore surfaces is possible.
  • FIG. 4 An alternative embodiment is shown in FIG. 4.
  • the connecting passage 50 are the result of connecting areas of the sand core, the forms the lower cooling chambers 22 in the block 12.
  • a bigger one Stability of the core can be provided be that the lower cooling chambers 22 with a small Connection forming the connection passages 50 connected becomes.
