Definitions

  • the invention relates to an oil exhaust cooling module for an internal combustion engine with a housing, an exhaust gas heat exchanger, which is arranged in the housing, an oil heat exchanger, which is arranged in the housing, coolant channels, which are fluidly connected to coolant chambers of the oil heat exchanger and the exhaust gas heat exchanger, exhaust gas ducts, which are formed in the exhaust gas heat exchanger and oil guide channels, which are fluidly connected to the oil heat exchanger.
  • Such oil-exhaust cooling modules are used to reduce the number of components and in particular the length of necessary lines.
  • the growing complexity of their design makes it necessary to arrange components as optimally as possible in relation to one another, thereby making optimal use of the small space available in the engine compartment of a vehicle.
  • such optimization is essential. This optimized use significantly limits the accessibility of the individual components, for example for inspections.
  • the oil filter extends through the exhaust gas heat exchanger to a side of the exhaust gas heat exchanger opposite the oil heat exchanger and is fluidically connected to the oil heat exchanger via the oil guide channels, which are arranged in the housing.
  • a housing part of the oil filter is formed integrally with an outer housing of the exhaust gas heat exchanger, whereby assembly costs are reduced and material stresses due to different expansions of two interconnected housing parts are avoided in the module.
  • an oil guide housing is attached to the crankcase of the internal combustion engine, on the opposite side of the oil cooler is fixed and in which an oil inlet is formed, which is connected to an oil outlet of the oil filter.
  • the exhaust gas recirculation valve is designed as a plug-in valve with a housing forming an exhaust gas passage.
  • the exhaust gas flow control is located in close proximity to the exhaust gas cooler, and here no additional lines are required.
  • a bypass channel is formed, via which an exhaust gas duct, which serves as a cooling area, can be bypassed, wherein the exhaust gas flow can be guided depending on the position of a bypass flap arranged in the housing either via the exhaust gas duct or via the bypass channel.
  • the exhaust gas heat exchanger can be bypassed with appropriate position of the bypass valve, whereby the warm-up phase shortened and thus pollutants can be reduced. Also by this integration, the number of otherwise required lines can be reduced.
  • a coolant inlet pipe and adeffenauslassstutzen are arranged on the outer housing of the exhaust gas heat exchanger, which establish a fluidic connection to a coolant chamber of the exhaust gas heat exchanger and in the oil guide housing coolant channels are formed, which establish a fluidic connection from the crankcase to the oil heat exchanger.
  • an oil-exhaust cooling module which is designed to save space and the functions of the exhaust gas quantities and temperature control and the oil cooling and oil and coolant guide integrated as a preassembled unit in the internal combustion engine module.
  • the position of the individual functional units to each other is chosen so that a very good accessibility for replacement parts, in particular the oil filter is given.
  • inventive oil-exhaust cooling module consists of a four-part housing 2, in which an oil filter 4, an exhaust gas heat exchanger 6 and an oil heat exchanger 8 are arranged.
  • a first housing part of the housing 2 is designed as an oil guide housing 10 and has three flange surfaces 12, 14, 16.
  • the first flange surface 12 serves to secure the module to a crankcase of an internal combustion engine and has an oil inlet 18, an oil outlet 20 and a coolant inlet 22 and a coolant outlet 24, as in FIG FIG. 2 can be seen.
  • connection housing 30 of the oil filter 4 is inserted such that two fluidic connections between the oil guide housing 10 and the terminal housing 30 in the region of the flange 16 with the interposition of a seal 31 arise.
  • the connection housing 30 of the oil filter 4 is formed integrally with an upper housing part 32 of the exhaust gas heat exchanger 6, which in turn is attached to the lower housing part 26.
  • the terminal housing 30 has, as in FIG. 3 can be seen, a thread into which a hollow screw 34 is rotated, by means of which an outer housing 36 of the oil filter 4 is fixed to the connection housing 30.
  • an outer housing 36 of the oil filter 4 is fixed to the connection housing 30.
  • Through the connection housing 30 extend two oil guide channels 38, 40, wherein over the oil guide channel 38 oil from the oil guide housing 10 flows to the oil filter 8 and via the hollow screw 34 and the oil guide channel 40 oil through the filter 42 flows back to the oil guide housing 10.
  • the oil filter 4 is fluidly connected via its connection housing 30 and the oil guide housing 10 to the oil heat exchanger 8, which is also supplied via formed in the oil guide housing 10 oil guide channels 44 with oil.
  • the connection housing 30 and thus the oil filter 4 thus extend from a side of the cooling module located below the exhaust heat exchanger 6 from the oil guide housing 10 through the exhaust gas heat exchanger 6 to the opposite side of the exhaust gas heat exchanger 6, so that the hollow screw 34 for opening the oil filter 4 after Installation of the cooling module is easily accessible from the top of the engine compartment, although the oil guide housing 10 is connected in the lower region of the engine to the crankcase.
  • the oil thus flows via the oil inlet 18 and an oil guide channel, not shown, formed in the oil guide housing 10 to an oil outlet, not shown, on the flange surface 16, which is connected to an oil inlet 48 of the connection housing 30 of the oil filter 4, so that the oil through the oil outlet and the oil inlet 48 in the oil guide channel 38 and filter 42 flows.
  • the filtered oil passes from here into the oil guide channel 40 and formed on a connection housing oil outlet 50, which in turn is fluidically connected to the flange 16 with an oil inlet 52 of the oil guide housing 10.
  • the oil flows to the oil heat exchanger 8, where it is cooled by the coolant.
  • the now filtered and cooled oil flows through a further oil guide channel 56 in the oil guide housing 10 to the oil outlet 20 and back to the motor housing.
