Definitions

  • a cooling system for a supercharged internal combustion engine having a liquid cooled jacket and supercharger air inlet means.
  • the supercharger air inlet means is provided with a pair of serially arranged heat-exchanger means to lower the temperature of the supercharger air.
  • the first of these heat-exchanger means receives cooling liquid from a liquid cooling circuit including the jacket of the internal combustion engine.
  • the other of these heatexchangers is located in the air inlet means between the engine and the first heat-exchanger and forms the part of a separate liquid cooling circuit provided with a circulation pump and air-cooled radiator.
  • the present invention is concerned with improvements relating to cooling devices for supercharged internal combustion engines, the special object of these improvements being the better utilisation of radiators, and, in consequence, a reduction in the number of dimensions of these radiators and/or improved cooling.
  • the invention applies to Diesel motors which are supercharged and have only one cooling-circuit, and likewise to motors having several separate cooling-circuits.
  • An auxiliary, or low-temperature circuit which cools the supercharging air for the engine, the lubricating oil, and if necessary the oil of a hydraulic transmission, etc.
  • Such an auxiliary circuit comprises at least one water/air supercharging heat-exchanger, a circulation pump, and in general, a water/oil heat-exchanger, except when the oil is cooled by a special auxiliary circuit.
  • the former In order to show the diiference between the high and low-temperature circuits, it can be indicated that the former must keep the engine water at temperatures of the order of 85 to 100 degrees C. (depending on whether the cooling system functions at atmospheric pressure or else is provided with pressurising means such as those described in French Pat. No. 1,252,170 and its additions Nos. 77,300, 78,838, 83,678, and in the French Pats. Nos. 1,338,447 and 1,339,626), while the latter circuit must keep the cooling-water of the supercharging air and/ or/ of the oil at temperatures in the region of 50 degrees C.
  • the efficiency of the low-temperature radiators which must function with a temperature-difference of about 20 degrees C. between the entry and the exit of the air, is much less than that of the high-temperature radiators, which, as is usual to save space, even if they receive at the entry the air issuing from the lowtemperature radiators, have a temperature difference of from 35 to 60 degrees C. If it is noted that the low-tem- 3,439,657 Patented Apr.
  • radiators as H.T. the more so because, as a result of the necessity of saving space, the radiators must be arranged in curtain formation, ie in pairs of radiators placed one behind the other, resulting in the fact that a large proportion of these pairs is made up of two B.T. radiators, and that the efficiency of these pairs is poor.
  • the invention aims to provide a cooling process, and cooling means which will remedy the difficulties arising in the B.T. circuit.
  • the supercharging air is cooled in two stages, respectively by means of the B.T. and H.T. circuits, as described in French Pat. No. 1,363,148, in the name of the same inventor, but a new arrangement of the H.T. circuit is used, which, going beyond the previous results, achieves advantageous results from the point of view of economy of construction and functioning behaviour of the cooling system.
  • the process according to the invention in order to cool a supercharged engine comprising one H.T. and one -B.T. cooling circuit, consists in the diversion, in parallel on H.T. radiators, of part of the water issuing from the H.T. circuit, and in the evacuation by means of this water of part of the calories contained in the supercharging air which is to be cooled, thanks to which the quantity of calories to be evacuated by the B.T. circuit can be reduced to a determined extend, and the number or the surface of the B.T. radiators can be reduced.
  • a cooling arrangement for a supercharged internal combustion engine, comprises; one main cooling circuit or H.T. circuit for the cooling of the engine proper; at least one auxiliary cooling circuit or B.T. circuit for partially cooling the supercharging air; as well as an additional circuit, which is diverted from the main circuit, in order partially to cool the supercharging air.
  • the H.T. circuit comprises at least the engines waterjacket, a pump and so-called H.T. radiators;
  • the B.T. circuit comprises at least one primary water/ air supercharging heat-exchanger, one pump and so-called B.T. radiators;
  • the diverted additional circuit is connected to the M.T. circuit in parallel on the H.T. radiators and comprises at least one secondary supercharging water/air heat-exchanger inserted into the said diverted circuit, the said secondary exchanger making up a first stage of supercharging air cooling, whose second stage is constituted by the primary exchanger.
  • a circulation pump which has an output which is more than is necessary for efficient functioning of the radiators, the abundant output of this pump being intended to cause very rapid water-circulation in the jackets and cylinder-heads of the engine so as to avoid hot points.
  • the abovementioned diverted circuit being connected in parallel to the H.T. radiators, the total output D of the circulation pump passes into the engine, as is desirable in accordance with the preceding. However, only a part d of this output passes into the H.T. radiators, which reduces the stresses to which these radiators are exposed as a result of the circulation, and allows a reduction in the cross-section of the channels, while the rest of the output D-d passes into the secondary supercharging water/air heat-exchanger.
  • a second independent auxiliary circuit comprising at least one pump, one water/air heat-exchanger and B.T. radiators, this-second auxiliary circuit cooling only the lubricating oil, while the first auxiliary circuit effects only the second stage of cooling of the supercharging air whose first cooling stage is effected by the diverted circuit abovementioned.
  • the invention is used to particular advantage in Diesel locomotive engines; this application will be mentioned in more detail in the following whether these engines be of classic type or of the type which is greatly supercharged, with a low compression ratio, e.g. of the type described in the patent application in France No. 48,222 filed Feb. 3, 1966 for Improvements in Supercharged Diesel Engines in the name of the same inventor.
  • Engines of this type can with advantage comprise only a single cooling-circuit (the H.T. circuit equipped according to the invention, with a diverted circuit connected in parallel to the radiators).
  • the cooling-water circuit comprises: a main branch comprising at least one pump and the engines water-jackets, arranged in series; a primary diverted branch from the said main branch, comprising at least one water/surrounding air raidiator; and a secondary diverted branch from the said main branch comprising at least one water/super charging air heat-exchanger.
  • the present invention is a cooling process for internal combustion engines consisting in passing the entire output of the engines cooling-circuit water through the engines water-jackets, then in dividing this entire output into a primary part which, cooling, passes through the radiators and then returns to the engine, and into a secondary part which passes in exchange of heat with the supercharging air for the engine, then returning to the engine.
  • the present invention is also a cooling device for a supercharged internal combustion engine in which the water-cooling circuit comprises: a main branch comprising at least one pump and the engines water-jackets, arranged in series; a primary branch diverted from the said main branch, and comprising at least on water/surrounding air radiator; and a secondary branch diverted from the said main branch comprising at least one water/air heat-exchanger, the air being the engines supercharging arr.
  • FIG. 1 diagrammatically illustrates an embodiment of a cooling system according to the invention
  • FIGS. 2 and 3 are respectively vertical and horizontal sections showing an arrangement of the radiators of this cooling system on board a locomotive;
  • FIG. 4 is a diagram of another embodiment of the coling system, with independent cooling circuit for the engines lubricating oil.
  • FIG. 5 is a horizontal section of the arrangement of the radiators as in FIG. 4.
  • the cooling system of the supercharged Diesel engine 2 shown in FIG. 1 comprises an H.T. circuit 4, a B.T. circuit 6, and a circuit 8, diverted from the H.T. circuit.
  • the H.T. circuit 4 comprises at least one radiator (or a group of radiators) 10, a pump 12, the engines waterjackets and the connecting pipes 14-16-18.
  • the B.T. circuit comprises at least one radiator (or group of radiators) 20, a pump 22, a water/oil heat-exchanger 24 cooling the engines lubricating oil (the pipes leading the oil to the exchanger are not shown) and a water/supercharging air heat-exchanger 26 which constitutes the B.T. stage of an exchanger 28 cooling the air blown by the supercharging turbo-compressor (not shown) of the engine.
  • the circuit is completed by connecting pipes 30-32-34-36.
  • the H.T. diverted circuit 8 comprises simply a water/ supercharging air heat-exchanger 38 which constitutes the H.T. stage of the exchanger 28, the said exchanger being connected as a diversion from the main circuit, in parallel on the radiator 10, by means of two pipes 40-42.
  • the two radiators or groups of radiators 20-10 are arranged in pairs i.e. one behind the other, and are successively exposed to the flow of air caused by one or more ventilators 44.
  • FIGS. 2 and 3 Shown on FIGS. 2 and 3 is the curtain formation of the radiators aboard a locomotive with diesel engine 46, the radiators being grouped in pairs in two curtains on each side of the locomotive.
  • each pair of radiators 20-10 In order that each pair of radiators 20-10 be put to the best possible use, each pair must be made up of one B.T. radiator and one H.T. radiator.
  • the invention allows this to be achieved, whereas in conventional cooling systems, the importance of the B.T. circuit led to its having many more B.T. radiators, especially since at full power this B.T. circuit had on its own to cool all the supercharging air, the temperature of this air being of the order of 200 degrees C. on leaving the compressor for a compression ratio of about 3. There therefore resulted the fact that certain pairs were made up of two B.T. radiators, of which the second one worked badly.
  • connection of the new circuit 8, diverted from the radiators 10, has numerous advantages; in fact all the output of the pump 12 goes through the engines waterjackets, which helps to avoid hot points, whereas the part 14-10-16 is only passed through by a fraction of this output, e.g. about half.
  • the result is that the cross-section of the pipes :14 and 16 (which are long) can be reduced, which is more economical and makes assembly easier, while at the same time the H.T. radiators 10 are no longer exposed to a violent and abundant output.
  • the other fraction of the output of the pump 12 passes through the supplementary pipes 40- 42 of the diverted circuit, but these pipes are extremely short (between the engine and the supercharging air inlet) and are therefore inexpensive.
  • the two-stage exchanger 28 is not much more important than the single exchanger which exists in conventional cooling systems.
  • the distribution of the output of the pump 12 between the two circuits 14-10-16 and 42-38-40 is so chosen as to obtain a calorific balance between the B.T. and H.T. circuits, this distribution being made according to the load losses in the two branches of the circuit, and being capable of adjustment, for example by means of one or two covers 50-50 of a chosen cross-section.
  • FIG. 4 Such an arrangement is shown in FIG. 4 where the water/oil exchanger24 is withdrawn from the B.T. circuit 6 which, otherwise, is identical to that in :FIG. 1.
  • the independent circuit 52 comprises the exchanger 24, a pump 54, and a B.T. radiator 56 (or a group of radiators), as well as the connecting pipes 58-6062.
  • the H.T. circuit 4 and the diverted circuit 8 are identical to what was described in relation to FIG. 1, except that two H.T. radiators 10 have been shown (which can be assembled in series or in parallel in the water) so as to constitute two pairs of B.T.-H.T. radiators; one pair 20410 and one pair 56-10.
  • Such an independent circuit 52 can improve the efiiciency of the radiators and in consequence lower the temperature of the air admitted to the motor, as a result of their better utilisation, without increasing appreciably the construction costs, for it is possible to reduce the output of the pump 22 and the cross-sections of the pipes of circuit 6, as this circuit no longer has to effect the cooling of the lubricating oil.
  • each H.T. radiator 10 is in series on the air, with a B.T. radiator (20 or 56), so that all the radiators are put to the best use.
  • B.T. radiator entry 30 deg. C., exit 50 deg. C. (At 20 deg.).
  • H.T. radiator entry 50 deg. 0., exit 95 deg. C. (At 45 deg).
  • each B.T. radiator can work paired with an H.T. radiator, so that: the B.T. radiators can evacuate:
  • the H.T. radiators can evacuate:
  • N H.T. radiators can evacuate 0.43Q, it will be necessary, in order to evacuate 0.69Q, a number N" of radiators (H.T.) such as 0.69 II N -N -1.6N
  • the B.T. circuit added 52 whose function is to maintain the lubricating oil at a temperature suitable (e.g. 70 deg. C.) for the water of this circuit, a temperature higher than that of the water of circuit 6, gives a better efliciency to the radiators 20 which can keep the supercharging air at a temperature lower than the 50 deg. C. aforementioned, whence an improvement in the engines functioning is achieved.
  • a temperature suitable e.g. 70 deg. C.
  • the total water output of the B.T. circuits i.e. the output circulating in the circuits 6 and 52 will be about half of the output which circulated in the circuit 6 of FIG. 1, which makes assembly easier.
  • the cooling circuit is limited to the following elements indicated in FIG. 2 or 4; a main branch which comprises the pump 12, the pipeline 18 and the engines waterjackets, into which therefore the whole output of the pump passes; a primary diverted branch comprising the pipes 14-16 and the radiators 10 into which there therefore passes only a fraction of the pumps output; a secondary diverted branch, in parallel on the primary diverted branch, comprising the pipes 40-42 as well as the heatexchanger 38 through which passes the supercharging air.
  • a cooling system for a supercharged internal combustion engine having a liquid cooling jacket and a supercharger inlet means; a first heat-exchanger means disposed in said supercharger inlet means arranged to absorb heat from the air passing therethrough; a second heat-exchanger means disposed in said inlet means between said first heat-exchanger means and said engine arranged to absorb heat from the air passing therethrough; a first high-temperature cooling liquid circuit including a first air-cooled radiator means, a first circulation pump means and said cooling jacket of said engine; a low-temperature cooling liquid circuit including a second aircooled radiator means, a second circulation pump means and said second heat-exchanger means for cooling supercharger air passing through said second heat-exchanger means down to a relatively low-temperature; and a second high-temperature cooling liquid circuit, including said first heat-exchanger means; said second high-temperature cooling liquid circuit being interconnected to said first high-temperature cooling liquid circuit at a point located near the liquid outlet of the engine and at a point located
