Definitions

  • the invention relates to a device for adjusting the compression ratio of an internal combustion engine.
  • This device comprises a connecting rod whose head receives the axis of the crankshaft and whose foot cooperates with a mechanism for adjusting the position of the piston.
  • This adjustment mechanism comprises an eccentric having a bore for receiving the piston shaft.
  • the eccentric turns on itself under the action of a lever whose center of tilting is also the center of rotation of the eccentric.
  • the lever extends on either side of the eccentric and comprises a first end and a second end. These ends are respectively connected to two rods, each of these rods slides in a corresponding compression chamber and made in the body of the rod. The pressure difference in these chambers causes the rods to move in opposite directions, allowing the lever to tilt to one side or to the other side. The tilting of the lever causes the rotation of the eccentric and thus the change of position of the piston head.
  • the compression chambers are supplied with oil.
  • a pilot valve for example type 3/2, communicates with these chambers and controls the supply or discharge of each of them.
  • the pilot valve is not part of the connecting rod.
  • the pilot valve is controlled at each motor revolution to rotate in a non-rotating guide.
  • This device is relatively complicated and involves a contact of the pilot valve whose movement is rotatable, with a non-rotating guide. This can result in audible slipping noise of the valve in the guide, or significant friction between these two elements. This increases the risk of pilot valve failure and guide wear. Therefore, this eccentric adjustment mechanism is unreliable and requires regular operation monitoring, which generally complicates the eccentric adjustment mechanism.
  • an object of the invention is to provide a compressor compression rate adjustment device reliable and easy to implement.
  • the connecting rod and the operating element are respectively made of materials having different coefficients of thermal expansion.
  • the respective dimensions of these elements will vary differently under the effect of variation of the engine temperature. Thanks to the differential expansion or retraction between the connecting rod and the operating element, the operating element can act on the lever and tilt to the desired side. Following the tilting of the lever, the eccentric turns on itself and changes the position of the piston, and therefore changes the compression ratio.
  • the adjustment of the compression ratio therefore depends on a characteristic inherent in the connecting rod and the operating element, here the coefficient of thermal expansion. In this way, there is little or no external element to the rod to control the action of the operating element on the lever, which makes the device according to the invention more reliable and less complex compared to a device of the state of the art using controlled actuators.
  • the device according to the invention is particularly suitable for a diesel engine.
  • the device according to the invention can be designed to put the piston in a position conferring a high compression rate to the diesel engine from its start.
  • this is not possible for state-of-the-art devices since the pressurized oil supply system of these devices is not operational at the time of starting the engine. Therefore, at this moment, the devices of the state of the art give a low compression rate to the engine, which will delay or even make it impossible to start it.
  • the invention also relates to an internal combustion engine equipped with at least one compression ratio adjusting device comprising at least one of the preceding characteristics.
  • the invention also relates to a vehicle equipped with such an engine.
  • a compression rate adjusting device 1 comprises a piston 2 mounted on a connecting rod 3, an eccentric 4 cooperating with the connecting rod 3.
  • the piston 2 comprises a piston head 21 connected to a piston shaft 22.
  • the eccentric 4 causes the piston head 21 to move from top to bottom, and vice versa, in the vertical direction F1 illustrated in FIG. figure 1 .
  • the rod 3 comprises three main parts: the foot 31, the body 33 and the head 34.
  • the small end 31 comprises a vertical slot and a first opening whose axis is horizontal and perpendicular to said slot.
  • the first opening receives a main shaft 41 of the eccentric 4. Since the illustrated views on the Figures 1 to 4 are cutting views of the adjusting device 1, the vertical slot and the first opening are not clearly visible.
  • the big end 34 comprises a second opening 35 which receives a crankshaft axis of the engine.
  • the connecting rod body 33 connects the foot 31 to the small end 34.
  • the eccentric 4 is installed at the small end of the connecting rod 32. Precisely, the eccentric 4 comprises a main shaft 41 fitted in the first opening so that once installed in said opening, the main shaft 41 can turn around. himself.
  • the main shaft 41 comprises an eccentric bore 42, i.e. it is offset from a center I of the main shaft 41.
  • the eccentric bore 42 is shifted to the left by relation to the center I of the tree 41.
  • the eccentric bore 42 is adapted to receive the piston shaft 22. This is held frictionally fixed once engaged in the eccentric bore 42.
  • the eccentric 4 further comprises a lever 43 secured to the main shaft 41.
  • the lever 43 comprises a toothed internal bore 430 having a shape complementary to a toothed portion 410 of the main shaft 41.
  • the lever 43 is housed in the vertical slot at the small end of the rod.
  • the lever 43 also comprises an arm 431 extending to the right from the toothed bore 430.
  • an operating element 44 is connected to the lever 43 at an attachment point 441 situated on the arm 431, or else called a top attachment point 441.
  • the operating element 44 is a rod 443 housed in a housing 330 formed in the rod body 33. Said housing 330 opens outwardly of the connecting rod body 33.
  • the rod 443 is connected to the rod body 33 at a hooking point 442 located at the bottom of the room, or also called low attachment point 442.
  • the adjustment device 1 makes it possible to adjust the compression ratio by changing the position of the piston head 21.
  • the distance between the upper end 210 of the piston head 21 and the center O of the second opening of the bottom is measured in the vertical direction F1 illustrated in FIG. figure 1 .
  • the operating principle of the adjusting device 1 is based on a differential expansion between two components of the device to act on the lever 43 and rotate the main shaft 41 of the eccentric 4. These two elements are the element of maneuver 44, here the rod 443, and the connecting rod 3.
  • the rod 443 is made of a material having a coefficient of positive thermal expansion while the connecting rod 3 is made of a material having a coefficient of thermal expansion substantially zero.
  • coefficient of thermal expansion substantially zero a value very close to zero value, for example less than or equal to 2 x 10 -6 K -1 .
  • the connecting rod 3 has a coefficient of thermal expansion of zero.
  • the position of the piston head 21 therefore affects the dead volume of the cylinder.
  • the piston head 21 is in the maximum high position in which the distance between the upper end 210 of the piston head 21 and the center O of the second opening 35 of the bottom has its maximum value d max .
  • the dead volume in this case, has a minimum volume, which corresponds to the highest compression ratio ⁇ max .
  • the state of the engine corresponding to the figure 1 is its state before starting, that is to say that the temperature in the engine is approximately identical to the ambient temperature T amb .
  • the rod 443 being made of a material having a positive coefficient of expansion, is in a retracted state at room temperature, as illustrated in FIG. figure 1 .
  • the rod 443 barely comes out of its housing 330 and directs the arm 431 of the lever 43 downwards.
  • the arm 431 in this low configuration positions the main shaft 41 so as to place the eccentric bore 42 at the upper left relative to the center I of the main shaft 41.
  • the piston shaft 22, or more exactly the piston head 21 is placed in the maximum high position as illustrated in FIG. figure 1 .
  • the piston head 21 is in the maximum down position in which the distance between the upper end 210 of the piston head 21 and the center O of the second opening 35 of the bottom has its minimum value d min .
  • the engine has reached a maximum temperature T max .
  • the maximum temperature may exceed the threshold temperature T threshold corresponding to an upper limit thermal capacity of the engine. This case is possible during the phases of the overboost during which the engine torque is temporarily higher than the permissible torque in continuous mode.
  • the overboost is achievable on an atmospheric diesel engine, that is to say a diesel engine without a forced supply system of the engine air, for example a compressor.
  • the rod 443 When the engine temperature reaches the maximum temperature T max , the rod 443 also reaches its maximum length by expanding, which is shown in FIG. figure 2 . Thus, by lengthening to its maximum length, the rod 443 pushes the arm 431 of the lever 43 upwards.
  • the main shaft 41 of the eccentric 4 rotates on itself in a direction F2 counterclockwise and places the eccentric bore 42 in the lower left relative to the center I of the eccentric.
  • the piston head 21 is therefore located in the maximum down position, which is to maximize the dead volume and thus to obtain the minimum compression ratio 15.
  • the rod 443 decreases the compression ratio thereof to a minimum value 15.
  • the connecting rod 3 has a coefficient of thermal expansion close to zero, or even zero, the dimensions of the connecting rod 3 do not vary much.
  • the compression ratio In a first time of use of the engine, that is to say just after starting it, the expansion of the rod 443 being low, the compression ratio remains relatively high. This is very beneficial for a diesel engine that needs a high compression ratio at startup.
  • the rod 443 In a second period of use of the engine, that is to say while the engine reaches a normal operating temperature, the rod 443 expands and acts on the lever 43 so that it lowers the piston head 21. The compression ratio is thus decreased. The compression ratio can be further reduced if necessary by triggering the overboost phase during which the engine reaches the maximum temperature T max .
  • this is a device for adjusting the compression ratio continuously, the characteristics of this device are advantageously used during long periods of high load: the high temperatures encountered under these conditions make it possible, by further reducing the compression ratio, to reduce the combustion temperature and therefore push the limits of reliability of the engine.
  • the location of the arm 531 and the operating element 54 is different from that of the first example, since the operating element 54 of the second example is made of a material having a coefficient of negative thermal expansion. In contrast, the rod 3 remains insensitive to changes in the engine temperature.
  • the operating element 54 according to the second example has an elongate stem shape 543 similar to that of the first example.
  • the piston head 21 is in the maximum high position.
  • the engine temperature is the ambient temperature.
  • the arm 531 of the lever 53 is held at the top and the main shaft 41 is in a position in which the eccentric bore 42 is located at the top left of the figure 3 .
  • the piston head 21 is in its maximum high position conferring a maximum compression ratio ⁇ max to the engine.
  • the distance between the upper end 210 of the piston head 21 and the center O of the second opening has a maximum value d max .
  • the motor temperature now reaches the maximum value T max .
  • the maximum temperature T max may exceed the engine threshold temperature representing the upper limit thermal capacity of the engine.
  • the engine can reach the maximum temperature T max during the overboost phases.
  • the rod 543 shown on the figure 4 , is in a maximum retracted state. Indeed, having a negative coefficient of expansion, the rod 543 retracts as the temperature of the engine increases. When the engine reaches the maximum temperature T max , the rod 543 is retracted to its maximum. In this configuration, the rod 543 holds the arm 531 of the lever in a low position in which the eccentric bore 42 is located at the bottom left of the figure 4 . Thus, the piston head 21 is in its maximum low position conferring a minimum compression ratio ⁇ min to the engine.
  • the rod 543 is weakly retracted, the compression ratio remains relatively high.
  • the rod 543 retracts little by little by directing the arm 531 downward.
  • the piston head 21 is thus lowered and reduces the compression ratio.
  • the compression ratio can be further reduced by triggering the overboost phase.
  • the distance of the lever arm di is changed between this high attachment point and the center I of the eccentric.
  • the greater this distance di is, the smaller the rotation angle of the eccentric.
  • the smaller the distance di the greater the angle of rotation of the eccentric.
  • the angle of rotation of the eccentric has a direct impact on the position of the piston head, thus on the compression ratio of the engine.
  • the lower attachment point of the operating element in the connecting rod body can be shifted to the right or to the left in order to adjust the rotation angle of the eccentric depending on the compression ratio wish.
  • the operating element is made of a material having a substantially zero or even zero thermal expansion coefficient
  • the connecting rod body is made of a material having a coefficient of positive thermal expansion.
  • the invar for the operating element and the steel for the connecting rod are made of a material having a coefficient of positive thermal expansion.
  • the operating element and the connecting rod may both have a coefficient of thermal expansion of the same sign, negative or positive, provided to respect a difference, in absolute value, predefined between the coefficients.
  • This difference can be of the order of 140 x 10 -6 K -1 .
  • the operating element is an elongated rod in the direction of movement of the piston.
  • the operating element may consist of an alternating succession of parts having the same coefficient of non-zero thermal expansion and of parts having the same coefficient of thermal expansion substantially zero, said parts being substantially parallel to the direction of movement of the piston head.
  • substantially parallel to the direction of movement of the foot of the piston is meant that the angle formed between the axis of the part concerned and the direction of movement of the piston is in the range of [0 °; 20 °].
  • a first part 65 having a non-zero thermal coefficient is arranged vertically.
  • the first piece 65 is connected at its lower end 651 to the body of the rod.
  • the first piece 65 is connected to an intermediate piece 66 at its upper end 652.
  • the intermediate piece 66 has a coefficient of zero thermal expansion.
  • the intermediate piece 66 from its link 661 with the first piece 65, joins a second piece 67, identical to the first piece 65, of the same length, of the same material in its lower part 671.
  • the lower part 671 of the second part 67 is located at the same level as that of the first part 65.
  • the second part 67 extends vertically upwards from the link 662 at the bottom with the intermediate piece 66.
  • the upper end 672 of the second piece 67 is connected to the lever.
  • the second piece 67 may be different from the first piece 65 depending on the need for expansion and the shape constraints imposed by the mechanical environment. For example, they may not have the same length or be made from different materials.
