Definitions

  • the disclosure relates to an internal combustion engine having exhaust gas cooling in the cooling jacket of a cylinder housing element.
  • Exhaust gas recirculation is a technique that is disclosed in, for example, EP-A-0 869 275 .
  • EGR may be used for controlling the generation of undesirable pollutant gases and particulate matter in the operation of internal combustion engines. This technique has proven particularly useful in internal combustion engines used in motor vehicles such as passenger cars, light duty trucks, and other on-road motor equipment.
  • the exhaust gas recirculation technique primarily involves the recirculation of exhaust gas into the intake air supply of the internal combustion engine. This exhaust gas thus reintroduced to the engine cylinder reduces the concentration of oxygen therein, which in turn lowers the maximum combustion temperature within the cylinder and slows the chemical reaction of the combustion process, decreasing the formation of nitrous oxide.
  • the exhaust gases typically contain a portion of unburned hydrocarbon which is burned on its reintroduction into the engine cylinder, which further reduces the emission of exhaust gas by-products which would be emitted as undesirable pollutants from the internal combustion engine.
  • pressure-charged intake air Another technique useful in the control and reduction of undesirable emissions from internal combustion engines is the use of pressure-charged intake air. This permits the use of relatively smaller cubic displacement and lighter weight internal combustion engines in a machine, for example, a mobile equipment, reducing in turn the specific fuel consumption of the machine and overall mass of the machine necessary to perform a given function.
  • the typical pressure-charging device may be controlled to provide improved emissions characteristics.
  • Pressure-charging machines suitable for such applications include the exhaust gas driven turbocharger which is comprised typically of an exhaust gas driven turbine linked to a turbine compressor disposed in the intake air stream to provide compression of the intake air.
  • the typical turbocharger is controlled by providing a gate which controls exhaust gas flow and gates exhaust gas to bypass the exhaust gas turbine and control the charging rate of the turbocharger so that the maximum pressure limits of the associated internal combustion engine are not exceeded.
  • Still another technique for controlling emissions used by many engine manufactures is the use of aftercooling the intake air thereby reducing the intake manifold temperature.
  • Some of the related art techniques have also considered intercooling the EGR gases by routing the recirculated exhaust gases through an aftercooler. It is known that lower intake manifold temperatures tend to reduce the formation of nitrous oxides found in the exhaust.
  • the exhaust gas to be recirculated may preferably be removed upstream of the exhaust gas driven turbine associated with the turbocharger.
  • the exhaust gas is diverted directly from the exhaust manifold.
  • the recirculated exhaust gas is preferably reintroduced to the intake air stream downstream of the compressor and air-to-air aftercooler.
  • the recirculated exhaust gas is reintroduced to the intake manifold. Reintroducing the exhaust gas downstream of the compressor and air-to-air aftercooler is preferred due to the reliability and maintainability concerns that arise should the exhaust gas be passed through the compressor and aftercooler.
  • a disadvantage of cooled EGR is that an aftercooler has to be added to the system. Such an aftercooler may be bulky and in most cases the space that is available for mounting the aftercooler is limited. The number of parts, the assembly costs as well as the maintenance costs may be increased. Further, an EGR system, especially a cooled EGR system, tends to significantly increase the volume of the engine.
  • the current disclosure aims to alleviate or overcome one or more disadvantages associated with the prior art.
  • an internal combustion engine may include a cylinder housing element having a wall structure defining at least one cylinder space and a cooling fluid jacket for cooling the cylinder housing element.
  • a gas channel may extend at least partly inside said cylinder housing element such that said cooling fluid jacket reduces the temperature of a gas in the gas channel.
  • Fig. 2 shows a cross section of a first embodiment of a cylinder housing element with a gas channel
  • Fig. 3 shows a cross section of a second embodiment of a cylinder housing element with a gas channel

  • a gas channel 58 may extend at least partly inside said cylinder housing element 50 such that said cooling fluid jacket 56 may reduce the temperature of a gas in the gas channel 58.
  • the EGR system 10 may include a gas conduit 34.

  • the diverted flow of cooled, compressed intake air within the bypass conduit 36 may likewise be controlled using a bleed air valve 44 operating under the control of the engine controller 42. It should be noted that the intake air bypass conduit 36 may also be omitted from the system.
  • Figs. 2 , 3 , 4 , 6 , 7 each show a schematical cross-section of an exemplary embodiment of a cylinder housing element 50.
  • the cylinder housing element may be a cylinder block 50 or a cylinder head of an internal combustion engine 12.

  • the wall structure 52 may also define a cooling jacket 56 around the cylinder spaces 54.
  • Fig. 2 depicts the cylinder spaces 54 as being arranged in a row, this is by no means necessary.

  • the bypass conduit 36 and the provision of a flow of bypassed intake air to the exhaust inlet 26 of the turbocharger 18 does not form an essential part of the present disclosure.
  • the diverted exhaust gas may be driven to the intake manifold 14 by the positive displacement pumping action of one or more designated cylinders.
  • the complete diversion of exhaust gas from one or more cylinders to the EGR conduit 34 may allow the EGR rate to be kept more or less constant without having to throttle the EGR valves 40.
  • the diverted exhaust gas since the exhaust gas may be diverted from the selected cylinders, the diverted exhaust gas may be typically pressurized above that of the exhaust manifold 16 and intake manifold 14.
  • the EGR system 10 may be adapted to operate within a broader range of engine operating conditions (i.e.
  • the depicted method may involve the steps of: (a) receiving fresh intake air 60 at the turbocharger 18; (b) compressing the fresh intake air 60 with turbocharger 18; (c) sending the compressed intake air 62 to the air-to-air aftercooler 20; (d) cooling the compressed intake air 62 using the air-to-air aftercooler 20 to yield cooled compressed intake air 64.
  • the method may also include the steps of (e) diverting a selected volume of hot exhaust gas 70 from the exhaust manifold 16 of the engine 12; (f) cleansing the diverted hot exhaust gas 70 using a particulate trap 38; (g) cooling the diverted hot exhaust gas 70 using the cooling capacity of cooling fluid inside the cooling jacket; and (h) forwarding the combined intake/EGR gas to the engine 12.
  • the method may also include: (i) replacing the hot exhaust gas 70 diverted from the exhaust manifold 16 with intake air 74 which may be heated and combining the intake air 74 with any remaining exhaust gas 76 to form a selected volume of discharge air 78; (j) driving an exhaust gas driven turbine 22 of the turbocharger 18 with the discharge air 78; and (k) forwarding the discharge air 78 to the exhaust system associated with the engine 12.
  • a gas channel 58 which may be in heat transferring contact with the cooling fluid in the cooling jacket 56 an improved component packaging compared to the conventional internal combustion engine with EGR-cooling may be obtained. Further, the number of parts necessary for providing EGR-cooling may be reduced and the amount of assembly operations may be reduced. In addition, the gas channel 58 may be less vulnerable to contamination with particles because the gas channel 58 can be comparatively large, relative to conventional gas/air heat exchangers. Especially, when the gas channel 58 is an integral part of the casting forming the cylinder housing element 50, the number of parts and the number of assembly operations may be reduced drastically relative to the prior art. Consequently, the proposed EGR-cooling is less expensive to manufacture and allows for improved component packaging relative to the prior art.
