Definitions

  • the present invention relates to an EGR/cooling integrated module for an IC engine.
  • EGR exhaust gas recirculation
  • An EGR system includes a number of components: an EGR cooler, i.e. a heat exchanger adapted to cool the exhaust gases before re-introducing them into the engine intake, a bypass valve associated to the EGR cooler and adapted to selectively route the EGR gases through the EGR cooler or bypass the cooler depending on engine operating parameters, and an EGR valve which controls the EGR flow rate.
  • an EGR cooler i.e. a heat exchanger adapted to cool the exhaust gases before re-introducing them into the engine intake
  • a bypass valve associated to the EGR cooler and adapted to selectively route the EGR gases through the EGR cooler or bypass the cooler depending on engine operating parameters
  • an EGR valve which controls the EGR flow rate.
  • the EGR cooler uses the engine coolant as the cooling fluid, therefore the module must be connected to the engine cooling system; furthermore, the EGR and bypass valve also require proper cooling because of the extremely high temperature of the exhaust gases.
  • This prior art module includes an EGR/cooling integrated module for an IC engine including an interface member adapted to be mounted to the engine, and further including an EGR valve, an EGR cooler and a bypass valve carried and interconnected by the interface member, wherein
  • An object of the present invention is to provide an EGR/cooling module that is more efficient and still more compact and less expensive to manufacture.
  • module 1 designates as a whole an EGR/cooling integrated module in accordance with the present invention (hereinafter "module 1".
  • Module 1 includes an EGR valve 2, an EGR cooler 3 and a bypass valve 4 that are carried and interconnected by a an interface member 5 (hereinafter "member 5") which is adapted to be directly assembled onto a vehicle IC engine (not shown).
  • Module 1 also includes an electrically operated EGR valve actuator 6, a vacuum-operated bypass valve actuator 7, a vacuum tank 8 for actuator 7, and a coolant thermostat valve 9 ( Figures 8 , 9 ).
  • Member 5 ( Figure 3 ) is conveniently an aluminium alloy die-casting and includes a plurality of internal passages for EGR gases and coolant, as will be described below in a more detailed manner.
  • Member 5 includes has a substantially flat base flange 10 ( Figure 2 ) which is adapted to be fixed to the engine and has, to this end, a plurality of peripheral bores adapted to receive fixing bolts (not shown).
  • Flange 10 is delimited by a flat surface 11 that rests, in use, against a corresponding wall of the engine; a gasket (not shown) is conveniently provided between the engine and surface 11.
  • Member 5 is provided with a coolant inlet aperture 12 and an EGR gas inlet aperture 13, both opening onto surface 11, so that they communicate with corresponding ports of the engine coolant circuit and, respectively, EGR gas circuit upon assembly onto the engine, with no need for additional connection tubings.
  • member 5 has a first lateral flange 14 for connection with EGR cooler and a second lateral flange 15 for connection with a subassembly 16 including vacuum tank 8 and thermostat valve 9, as better described hereinafter.
  • EGR gas inlet aperture 13 communicates with a through cavity 17 ( Figure 4 ) extending across member 5 and a tubular housing 18 integrally protruding from member 5 on the side opposite to base flange 10 and enclosing a control assembly 19 of the EGR valve 2.
  • EGR valve 2 is not a conventional, drop-in valve provided with an housing of its own; rather, the housing of EGR valve 2 is constituted by member 5, which delimits a valve chamber 20 defined by a portion of cavity 17.
  • Valve chamber 20 communicates with an EGR valve outlet passage 21 internal to member 5 and leading to bypass valve 4.
  • Control assembly 19, which can be of any known type, according to the present embodiment includes a disk shutter 22 which is rigidly fixed to an end of an axially sliding stem 23.
  • a spring 24 is housed in a spring chamber 28 within tubular housing 18, and is axially compressed between a stop member 25 fixed to an opposite end of stem 23 and a fixed shoulder 26, defined by member 5 and located between valve chamber 20 and spring chamber 28, so as to bias disk shutter 22 against an annular valve seat 27 axially interposed between gas inlet aperture 13 and valve chamber 20.
  • EGR valve actuator 6 is assembled axially onto the tubular housing 18 and controls the axial position of stem 23 so as to vary the EGR gas flow through a port formed between valve seat 27 and disk shutter 22.
  • Bypass valve 4 ( Figure 5 , 6 ) includes a valve chamber 31 provided within member 5 and having an inlet port 32 communicating with EGR valve outlet passage 21, a first outlet port 33 communicating with a cooler gas admission duct 34 and a second outlet port 35 communicating with a gas exit duct 36, as well as with a cooler gas return duct 37.
  • Bypass valve 4 also includes a flap 38 that is pivotally mounted within valve chamber 31 about a pivot 39, and may rotate between a first position ( Figure 5 ), in which second outlet port 35 is closed and inlet port 32 communicates with first outlet port 33, and a second position ( Figure 6 ), in which first outlet port 33 is closed and inlet port 32 communicates with second outlet port 35.
  • Cooler gas admission duct 34 and cooler gas return duct 37 open onto a front surface of flange 14 to form a gas inlet chamber 40 and a gas outlet chamber 41 ( Figure 3 ).
  • flap 38 is controllable by means of vacuum-operated actuator 7 ( Figure 1 ), having an axially reciprocating actuating rod 42 that is coupled to pivot 39 of the valve flap 38 by means of a link 43 having one end rigidly connected to pivot 39 and one end articulated to rod 42.
  • member 5 internally defines a cooing circuit including a main cooling cavity 46 which communicates with coolant inlet aperture 12 and extends adjacent to base flange 10 beside the EGR valve chamber 20 and below bypass valve chamber 31 ( Figure 3 ), so as to provide optimized cooling to both chambers.
  • Cooling cavity 46 is a blind cavity whose inlet 47 is closed, in use, by a cover 48 (only partially shown in Figure 3 ). Inlet 47 has thus no function but to allow cavity 46 to be obtained by introducing a movable core during casting.
  • Cooling cavity 46 serves as a coolant distribution chamber and communicates with a plurality of ducts provided within member 5, namely a cooler admission duct 49 ending with an opening 50 on first lateral flange 14 and a thermostat inlet duct 51 ending into a thermostat chamber 52.
  • Thermostat chamber 52 opens onto lateral flange 15 to receive thermostat valve 9, as hereinafter explained. It is to be noted that ducts 49 and 51 significantly contribute to refrigerating member 5 and, therefore, EGR valve 2 and bypass valve 4.
  • EGR cooler ( Figures 5 to 7 ) includes a housing 53 laterally delimiting a cooling chamber 54 that is closed at both ends by a first and second head plates 55, 56 supporting internal tubes collectively referenced 57.
  • First head plate 55 also has a circular coolant inlet opening 58 communicating with cooling chamber 54.
  • Internal tubes 57 have their opposite ends engaging respective bores 59 in head plates 54, 55 and are sealingly brazed therein. Internal tubes 57 form two different sets 57a, 57b; tubes 57a face gas inlet chamber 40, tubes 57b face gas outlet chamber 41.
  • EGR cooler also includes an end cup member 60 which is peripherally brazed to head plate 55 so as to form a distribution chamber 61 connecting tubers 57a to tubes 57b.
  • EGR cooler 3 includes a mounting flange 62 which surrounds housing 53 at head plate 55, and is adapted to be mounted to first lateral flange 14, with an interposed gasket not shown, so that coolant inlet opening 58 is connected to cooler admission duct 49, tubes 57a are connected to gas inlet chamber 40, and tubes 57b are connected to gas outlet chamber 41.
  • EGR cooler 3 includes two coolant outlets 65, 66 provided on housing 53 and adapted to be connected to external devices using engine coolant, such as an oil cooler and a cabin heater (both not shown).
  • Coolant outlets 65, 66 conveniently include quick connectors, rather than conventional spigots, so as to provide the utmost packaging flexibility. The same module can thus be used in different applications, as layout differences are dealt with by connecting pipes.
  • FIG 8 shows subassembly 16 in greater detail.
  • Subassembly 16 includes a single-piece plastics body 67 forming vacuum tank 8 and a coolant outlet pipe 68 adapted to be connected to the vehicle radiator.
  • Subassembly 16 includes a mounting flange 69 surrounding an inlet 70 ( Figure 8 ) of the outlet pipe 68; thermostat valve 9, per se known and not described in detail, includes a control assembly 71 which is pre-assembled onto the mounting flange 69 in a cantilever fashion, so as to be housed into thermostat chamber 52 when the subassembly is mounted onto second lateral flange 15 of member 5.
  • Control assembly includes a shutter 72 cooperating with inlet 70 to define a variable port.
  • Shutter 72 is balanced between a closure force exerted by a biasing spring 73 and an opening force exerted by a heat-sensitive linear actuator 74, e.g. a wax actuator.
  • Coolant enters module 1 through inlet aperture 12 and reaches main cooling chamber 46. It is to be noted that chamber 46 receives the whole flow rate of coolant exiting from the engine. Therefore, member 25 is cooled efficiently.
  • Coolant is splitted into two flows: a first flow is routed via duct 49 to refrigerating chamber 54 of cooler 3, and hence to coolant outlets 65, 66.
  • thermostat valve 9 Flow rate to outlet pipe 68, and thus to the vehicle radiator, is controlled by thermostat valve 9.
  • Gas flow is controlled by EGR valve 2, that is located on the "hot side", i.e. upstream, of the EGR cooler 3.
  • Flow rate is controlled as a function of engine operating parameters.
  • EGR valve 3 gases flow along valve outlet passage 21 and arrive to bypass valve 4. Depending on the engine operative conditions, EGR gases are either routed to EGR cooler 3 or to gas exit duct 36 directly, thus bypassing EGR cooler 3.
  • gases flow through tubes 57a, distribution chamber 61, tubes 57b, gas cooler return 37 and gas exit duct 36, which in use is connected to engine air intake system (not shown).
  • module 1 An analysis of module 1 reveals the advantages brought by the present invention.
  • the module includes a stand-alone EGR valve 2 that is mounted directly within member 5, i.e. without a casing of its own. This allows valve 2 to be cooled very efficiently and thus to be located on the hot side of EGR cooler. Positioning EGR valve 2 on the hot side of the cooler, when the engine layout so permits, allows module 5 to be more compact with respect to the prior art, and thus cheaper. Also, since EGR valve is subjected to hotter gases, the risk of sticking due to fouling with residual combustion products is reduced.
  • Integrated subassembly 16 including vacuum tank 8, coolant outlet tube 68 and thermostat valve 9, contributes to reducing assembly costs and to making the module more compact and cheaper.
  • FIG. 10 discloses a different embodiment of EGR cooler 103, that is described hereinafter using the same numerals as for cooler 3 to reference like parts.
  • head plate 56 is obtained in a single piece together with lateral housing 53.
  • housing 53 integrally includes an outwardly bent planar flange 104, onto which head plate 55 is brazed.
  • Housing 53 also has a lateral bulge 105 adjacent to flange 104.
  • Head plate 55 is stamped so as to form a short inlet sleeve 106 that is axially aligned with bulge 105; in this manner, coolant inlet does not subtract any useful volume inside cooling chamber 54, that can therefore be totally occupied by internal tubes 57.
  • Sleeve 106 sealingly engages an OR sealing 107 provided within opening 50 of flange 14.
  • Flange 62 surrounds housing 53 and backs flange 104 on the side opposite to flange 104 to increase the mechanical strength of the coupling; in this manner, there is no contact between flange 62 and member 5 and flange 62 can be made of carbon steel or aluminium or sintered material, rather than stainless steel, and thus be cheaper.
  • flange 62 can be made in two parts connected to one another by means of dovetail joints 108.
  • Tubes 57a, 57b, end cup member 60 and coolant outlets 65, 66 are identical to corresponding parts described with reference to cooler 3.
  • Cooler 103 that is particularly compact and efficient, can obviously be used in any different applications requiring a double-pass cooler.
  • the EGR valve actuator can be of any type and can be assembled differently onto interface member 5.
  • the bypass valve actuator can be of any type other than a vacuum-operated actuator, e.g. an electrical actuator or a pressure-operated actuator.
