However, this assembly does not show the expert Complete module with which there is also the possibility, especially in the lower one Speed range of the internal combustion engine optimal discharge of Achieve crankcase gases.
  • this object is achieved in that components form a module are summarized and that means are provided with which the module with the Internal combustion engine is connectable.
  • the advantage here is that both the manufacturing costs of the individual functional units as well as the costs of final assembly and the weight can be reduced. Due to the structural consistency, synergies are created achieved between the various functional units that lead to the above-mentioned cost savings contribute.
  • the provision of modules for final assembly also simplifies the Logistics.
  • the modular structure of the unit also has a positive effect on recycling of the assemblies.
  • the functional units can be combined into one module in addition, a quick reaction to changed marketing concepts.
  • the invention further provides that a carrier body is integrated in the module, which with the Internal combustion engine is connectable and to which the components of the module are attached.
  • This Carrier body gives the module a structure that connects the module with the one hand Internal combustion engine also defines the arrangement of the individual components of the module. A It would be possible, for example, to use the air filter box as a carrier body.
  • the module is essentially a component Includes crankcase pressure control valve and an idle vacuum valve, all in one Functional unit are summarized, leading to both weight and Cost savings leads.
  • the device communicates with the crankcase and / or the filter space, in particular with its clean air side. This guarantees that those responsible for emissions Crankcase gases remain in the overall system of the internal combustion engine and that Combustion process are fed.

  • the advantage lies in the combination of functional groups, that are in an effective context, because in this way both communication channels, Take off the housing dimensions and the total weight of the assembly to be considered.
  • crankcase pressure control valve acts as the carrier body of the module, by means of which the module with the Internal combustion engine is connectable.
  • the advantage as a structural body of the module lies in its spatial extension as well as in its functionality, which is a direct contact anyway to the housing of the internal combustion engine may appear advantageous, justified and in the The fact that it has a certain basic strength of the housing.
  • At least one component of the Module consists of plastic. Even the complete version of the module and its Plastic components are conceivable. The execution of the module in plastic leads inevitably to cost savings and weight reductions, and subsequently to one low fuel consumption of the internal combustion engine in operation.
  • An advantageous development of the invention provides that the module in, on or on Cylinder head or its cover is integrated, resulting in short communication paths and small housing dimensions leads, as part of the cylinder head or its cover as Module housing can also be used. It would also be conceivable to have the module in or on Attach air filter box, since functional relationships exist here too.
