Definitions

  • the invention relates to a cylinder housing for a Hubkolbenvorraum and a method for producing such a cylinder housing.
  • the invention also relates to a reciprocating device with such a cylinder housing and an internal combustion engine with such a reciprocating piston device.

  • Internal combustion engines are usually cooled by means of a cooling liquid which, conveyed by at least one coolant pump, circulates in a cooling system of the internal combustion engine which integrates the cooling jacket. Due to the circulating coolant heat energy can be dissipated by the internal combustion engine to at least one ambient heat exchanger, in which the heat energy is then released to, for example, the ambient air.
  • Most known internal combustion engines have cooling jackets, which surround the individual cylinders with respect to the circumference at least partially and with respect to the longitudinal extent substantially completely. Integration of a coolant inlet occurs in the region of top dead center in most known internal combustion engines in which the cyclical reciprocating movement of the piston guided in the corresponding cylinder is reversed and in the vicinity of which a combustion of a fuel-fresh gas mixture in the Cylinder is introduced while an integration of a coolant outlet is provided in the vicinity of the bottom dead center of the piston movement.
  • the local, along the longitudinal extent of the cylinder or the cooling cooling requirement can not be optimally fair, because it is sufficient dimensioning of the cooling system including the cooling jacket with respect to the cooling power requirement in the top dead center of the piston movement in this area is highest because of the there primarily occurring combustion processes, can lead to a "overcooling", ie to a strong cooling in the other areas.
  • too low a temperature of a cylinder wall often leads to a relatively high viscosity of the friction of the relative movement between the cylinder wall and the associated piston low-holding lubricant and thus to relatively high friction losses and a relatively high wear during operation of the internal combustion engine.
  • cylinders of an internal combustion engine can each be delimited by a so-called cylinder liner, which in turn are respectively received in an associated receiving opening of a cylinder housing.
  • cylinder liners can be designed as so-called "wet" cylinder liners whose outer walls bound each with the walls of the associated receiving openings an annular gap which serves as a cooling jacket. So far, such wet liners are mainly used in truck engines and large engines.

  • the (wall) surface which comes into contact with a coolant provided for flowing through the cooling jackets can be markedly increased in comparison to conventional cooling jackets, resulting in a correspondingly high heat transfer of the cylinder housing can be reached on the coolant.
  • a reduced volumetric flow of the coolant can thus lead to a reduced delivery rate for a working machine (pump with a preferred use of a cooling liquid or compressor with a likewise conceivable use of a cooling gas as coolant), which has a positive effect on both the costs and also can affect the weight of the machine and thus a comprehensive such a working machine Hubkolbenvorraum.
