Definitions

  • the invention relates to a sound-absorbing cover for a Internal combustion engine with a cooling air blower, from which is flowing Cooling air in an area having injectors between cover and cylinder head with cylinder head cover leads, according to the preamble of claim 1.
  • DE-AS 24 57 834 is a generic soundproofed Internal combustion engine with cooling air fan known, which is sucked Cooling air via an inlet opening against the ones to be cooled Places on the cylinder and cylinder head as well as fuel-carrying Promotes parts.
  • the one in the soundproofing formwork incoming cooling air flow is divided into partial flows, in separate cooling air ducts to outlet openings of the casing reach.
  • the cooling air ducts are through a side the intermediate wall or the cylinder head cover Bulkhead separated.
  • the invention has for its object on an internal combustion engine simple measures to be provided with a sound-absorbing cover, which a compact cooling air flow to the particularly effective Reduction of operating fluid and component temperatures enable. Furthermore, the cover is also intended for internal combustion engines suitable with such fuel injection systems be operated at very high pressures and thus exposed to very high temperatures.
  • the bulkhead which is also the boundary wall for the nozzle area represents, especially at high pressure levels working injection systems a not insignificant safety aspect, since there are no leaks on the injection side can reach the hot exhaust or exhaust side. Much more leakage can flow away safely on the cold inlet side.
  • the oil separator is thus from the cooling chamber through which the cooling air flows isolated.
  • a sound-absorbing cover 1 for a multi-cylinder internal combustion engine 2 is shown in Fig.1.
  • Cover 1 covers essential parts of the four-cylinder internal combustion engine 2, namely a cylinder head cover 3, an oil separator 4, all in the cylinder head 5 inserted injection nozzles 6 and associated High-pressure lines 7, the one as a high-pressure accumulator acting common rail 8 of a common rail injection system are connected.
  • the cylinder head cover 3 In the area of all injection nozzles 6 is the cylinder head cover 3 retracted and forms a central one and extending in the longitudinal direction of this cylinder head cover 3 deep hollow, with passages for the respective Injection nozzles 6 provided trough bottom 3b flat on the cylinder head 5 rests.
  • the retracted section of the cylinder head cover 3, an exhaust side Bulkhead 10, one opposite this bulkhead Boundary wall 15 and a flat cover part 1 a Cover 1 form the channel-shaped nozzle space 9 (Fig. 2,3).
  • the bulkhead 10 lies laterally on the side wall 3c of the trough while the boundary wall formed on the cover part 1a 15 formed on one on the cylinder head cover 3 towering longitudinal web 3d, which extends over the Length of the cylinder head cover 3 extends.
  • the oil separator 4 is on the cold inlet side opposite hot exhaust or exhaust side.
  • the cooling air flowing out into the nozzle chamber 9 is passed and brushed all the injection nozzles 6 and cools.
  • the cooling air flow is at one of the cooling air blowers 12 facing away from the end of the internal combustion engine 2 deflected an end wall 16 of the cover 1 and runs in an obliquely downward cooling air line 13 to one Side exit of the cooling air flow on the cold inlet side to reach.
  • the cooling air flow still detects one in the flow path lying pressure control valve 14, which at one end of the common distributor line provided for all injection nozzles 6 8 is arranged, which is just below the outlet the cooling air line 13 is located at the lower end of the cover 1.
  • FIG. 1 In the area of the cooling air line 13, the elevated one is shown in FIG Hood part of the cylinder head cover 3 with a cross to the cylinder head cover provided web-free indentation 17, the together with the pulled down boundary wall 15 one provides an adequate passage cross-section for the cooling air flow.
  • the cylinder head cover 3 is on its raised hood part ( Figure 3) equipped with further indentations 18 with a corresponding passage 19 in the boundary wall 15 a non-contact course of the respective injection line 7 of enable the distributor line 8 to the injector 6.
